Not everyone can afford expensive metal doors, and there is absolutely no need for them in a country house, so country residents install wooden doors with good heat transfer properties. The door, whether it is made of birch or pine, must first of all withstand cold air currents, street noise, and protect residents from extraneous unpleasant odors or debris.

Of course, it is impossible to imagine a door without a base - a box where it is ultimately installed, but it is very, very difficult to accurately bend all the dimensions of both parts, so gaps and cracks arise through which the cold will enter.

Seals for wooden doors, and our review will help you choose a decent option

What are there

Wood itself is a very malleable material; it can both absorb moisture and dry out from sunlight or heat from a stove, so its dimensions can change in one direction or another. But doors can be both entrance and interior, so each of them needs its own seal, because what will be especially good at protecting from street noise and bad weather. It may be completely unsuitable for a door located between rooms.

• Foam options. These are relatively cheap seals that look like tape. But they cope poorly with their direct task, resisting the cold, and in just half a season they can completely fail. But these materials are suitable for arranging the interior door leaf; they will stop slamming and creaking when opening and closing. But if there are no other options, then choose wide foam products and install them with glue or small nails.

• PVC products with rubber gasket. This is already a worthy option, polyvinyl chloride itself is resistant and durable, and the thin rubber gasket ideally flows around the contour of the door and does not let anything unnecessary into the house.

• Rubber products for seals entrance doors . In fact, this is a universal option; they will fit almost any door leaf – whether made of wood, plastic or metal. There are self-adhesive and simple rubber seals. Installation of the self-adhesive product is very simple - just remove the protective film, distribute it along the contour of the door, and press a little, and it will sit in place. They produce similar products in a variety of sizes, and there is always wide choose the desired option. The cost will be low, and the service life will be very long. When purchasing, carefully study the label, the material can last either 3 or 9 years, it all depends on the composition, the label will definitely tell you how long this seal is designed for.

• Silicone products. Its main characteristics are very similar to the rubber options, and the installation is absolutely the same. But over time, the structure of silicone changes, it will somewhat resemble office glue, so it ceases to perform its main functions, and in some places even falls out of its place.

• Thermoplastic elastomer seals. These are very durable and at the same time elastic products, meet all accepted environmental requirements, and are not afraid of sudden changes. temperature regime, and remains with the same characteristics even with strong negative temperatures. Aesthetically pleasing and durable, it can protect the front door from the cold for up to 30 years without noticeable changes. But, as they say, you have to pay for pleasure, and this is probably the most expensive material. For installation, you need to make special slots in the door, that is, mortise seal, which may cause some inconvenience, the groove must be at least 5 mm. When installing, pay attention - one side has notches in the form of a herringbone, it is this that should be inserted into the groove, and when hit, it will immediately open, that is, it will be securely fixed and will no longer change its position.

• Self-adhesive mainly used for compaction interior paintings doors, these are lightweight and at the same time practical seals that seal individual living spaces well - sound practically does not penetrate, the doors do not slam against the jamb, which is undoubtedly convenient. And they are quite cheap. Modern technological processes have made these materials resistant to sunlight; they can withstand any temperature changes well.

• Special threshold seals. They will not only reliably protect the door from the penetration of cold, but at the same time they will be able to clean dirty shoes from large fractions of dirt - brushes will cope with this task; they are inserted into special profiles and laid along the contour of the lower base.

A little more about mortise products

A distinctive feature of such seals at the installation site is that they are installed around the perimeter of the door frame, instead of the door itself. This is much more convenient than making cuts in the door itself.

But on sale you can find ready-made options - already attached to the door quality material, which will help the door to come into closer contact with the frame.

Installation

Let's look in detail at how to seal a door using a mortise rubber product:

• Calculate the perimeter of the doorway; the material should be purchased with a small margin;
• You will need a special milling tool to cut the size of the slot you need;
• Carefully make the grooves according to the markings to the required size;
• Take the seal, and slowly around the perimeter, sequentially tuck it into the groove in the desired direction (installation instructions are usually included);
• Check your work, put the door on the frame.

If a simple sealing material is chosen, then it should be glued both along the door leaf itself and along the contour of the frame to achieve the best result.

Manufacturers and prices

• Silicone guide seals, made in China, size 9x6 mm, cost per linear meter - 192 rubles, color scheme imitates door veneer;
• Self-adhesive tapes, a linear meter costs 665 rubles, made in China, various color shades;
• Delivery in whips, type - combined, magnetic self-adhesive, manufacturer Russia, price of 1 piece of product - 100 rubles, various colors.

The sealing tape has not only the function of protecting the home from drafts. In the fight against extraneous sounds coming from the street, the seal can also play an important role. When choosing, you should pay attention to several aspects: types of seals, the materials from which they are made, and also use tricks that will help you choose the right door insulation.

Functions

The most important function of the seal is protection from drafts. If a device cannot cope with this task, it is a priori of insufficient quality. This is especially true for entrance doors: thermal insulation in this case is extremely important, and only a sufficient level of insulation can ensure it. An important thermal insulation function “works” in both directions, simultaneously protecting the apartment from cold wind from the street or from the entrance and preventing heat from escaping from the home. It is estimated that unsealed doors release up to 40% of all heat generated heating devices. Heating prices are currently quite high, so no one wants to waste precious heat.

Speaking about thermal insulation, one cannot fail to mention that a number of products can withstand significant temperature fluctuations. The amplitude can vary from -65 to +95 degrees Celsius. Thus, by installing high-quality insulation on the front door, you don’t have to worry about it cracking in summer or winter.

Another advantage of the seal is its noise-insulating properties. They are inherent in both metal water doors and interior doors. It happens that the front door is right next to a road or a playground, and the insufficient level of sound insulation does not allow residents to feel comfortable enough, because annoying sounds from the street are very disturbing. If the rooms are not well isolated from each other, then another problem arises: the impossibility of everyone doing their own thing without the risk of disturbing the other. Good sound insulation makes situations comfortable when, for example, they play the piano in one room and read in another.

Shock absorption properties are another important factor. Everyone has encountered a situation where in the summer, due to open windows, drafts flow through the house, and the doors close with a strong bang, disturbing not only the residents of the house, but also their neighbors. Sealing tape conceals unpleasant sound, preventing the creation of annoying slams, as well as extending the service life of the door and door frame (due to sudden slamming, they wear out faster).

The seal protects the house well from unnecessary odors or smoke. For example, something may burn in the kitchen. No one wants the “aroma” of burning to instantly spread throughout all the rooms, so insulation will help keep the smell out only in the kitchen. The same can be said about the door to the bathroom: it is better to leave wet steam directly within the bathroom and not let it out into the hallway or corridor.

Thus, the main property that a door seal has is sealing the door leaf. In the Russian climate, this property of the door is extremely important due to strong temperature changes on the streets. Moreover, you should carefully consider the choice of product if you live in a large, noisy city, because many cities are very busy both during the day and at night. It is for such “sleepless” cities that doors with seals for enhanced sound insulation are well suited. When choosing a door to the kitchen, you also need to make it as airtight as possible, because it is not always appropriate and pleasant when food smells are heard, for example, in the bedroom.

Kinds

Seals are classified according to several criteria. The first of these is the type of door:

• For entrance doors. The door seal for entrance doors is usually made tubular. The profile with a cavity inside completely ensures a sufficient fit of the door, contributing to complete isolation from external influences.
• For interior doors. Here completely different requirements are presented: there is no need to protect the room so strongly from the environment; the aesthetic component comes first. In some cases, isolation is important (for example, in the bedroom), but not required.
• For plastic doors. Seals for plastic doors are placed in a separate category, since they differ significantly from seals for ordinary doors. It is necessary that the groove element reacts well with environment. As a rule, such seals are installed on balcony doors. Please note that generally for plastic the door will fit only a part that is produced by the same manufacturer as the door itself.
• For glass doors. The profile, which is attached directly to the glass, can be aluminum or silicone. Silicone elements must have a special cross-section; they also serve as insulation, while on aluminum profile have to do special seal made of rubber. Silicone glass seal is suitable for rooms with high humidity, since there is no risk that he will “move away”.

Based on materials, the following types are distinguished:

• Rubber.
• Silicone.
• Foam rubber.
• Magnet.
• Thermoplastic.
• Felt.

According to the configuration, the following types are distinguished:

• Tape. It is a soft cord with rectangular cross-section, the width of which is approximately 9 mm.
• Tubular. Despite the fact that a tube seal is most often used for entrance doors, it boasts less sealing properties than tape models. It is a hollow tube inside, which is pressed when closing the doors, due to which there are no gaps between the door leaf and the frame.
• Groove. Made specifically for plastic doors, it is a hollow profile made of soft rubber, on one side of which there is a special brush installed in the grooves. This reduces the impact external environment on the seal and is almost completely transferred to the door leaf itself.

• Spring-loaded. Attaches to the door frame, not the door. When closing, its parts slide along the spring and close the cracks. Suitable only for fastening on perfectly flat surfaces.
• Mortise. Made for wooden doors. It is specially cut for such a seal. small niche in the door frame, allowing you to fit the door leaf tightly in the future. A rubber profile is attached to the niche.
• Folding. Suitable for sealing folding doors, folding doors and similar structures.

Tape seals are rarely made wider than 10 mm. This is due to the fact that this width is optimal both for attaching around the perimeter of the door leaf and for the door frame. Tubular options generally have the same characteristics, regardless of what material they were made from. The size of the seal for a plastic door depends entirely on the manufacturer. It often happens that for each specific door model only one single model of seals is suitable, and there is no way to replace it with an analogue. It is recommended to pay special attention to this issue when choosing a door, whether it is possible to replace parts with those purchased from another manufacturer, otherwise during repairs you may need to replace the entire door.

A complex rubber profile remains a universal choice, suitable for both interior and entrance doors. It is released in various options, can be made of soft rubber or more dense, the width of the profiles is traditionally 8-10 mm.

• Foam rubber It is better not to use the element for entrance doors and save it for interior structures. The fact is that foam rubber is not the most durable material and will simply not withstand the kind of use that the front door is subjected to. Foam rubber is quite cheap, but it copes well with the basic functions of the seal. It is best to use foam inserts for doors that are subject to little use, for example, to a living room.
• Unlike foam rubber, magnetic constructs are used only for entrance doors. Magnetic inserts on soft rubber profiles guarantee the best sealing fit, so protection against drafts or heat leakage from the house is guaranteed. Problems can only arise with the installation of the elements; they must be selected exactly to the size of the door, otherwise the magnetic protrusion simply will not allow the door to close.

Another current option is colorless insulation. Many believe that they are good decision only for glass doors, however, this is far from the case. The transparent seal looks great on wooden, plastic, and metal doors, since it is practically invisible. Thus, it can be used in cases where the owner is afraid of spoiling the aesthetic appearance of the door or if, from a stylistic point of view, the use of a seal is inappropriate.

According to texture, the following types are distinguished:

• Flexible. Smooth or flexible profiles can be made from a variety of various materials, including rubber, silicone, magnet.
• Liquid. Usually used when insulating entrance doors. It is some semblance of liquid foam rubber, which is applied to the desired areas under pressure.
• Pile. The fleecy option is very familiar to many, since felt was originally the only alternative for making door insulation. At this stage of development of the repair business, they produce a harness and tape not only from pure felt, but also from synthetic fleecy fabric.

The following options are available by location:

• Threshold. They are a good solution in cases where the door design does not provide for a threshold. Mainly done on automatic control, which allows the profile to “adjust” to the width of the gap between the door and the floor in the open or closed position.
• Contour. Outline options are the easiest to understand. They are attached along the entire perimeter of the door leaf or frame, simultaneously eliminating cracks everywhere. Most often used for entrance doors, a triple profile is used.
• Firefighter. This thermally expanding option is a substance that turns into foam when heated strongly. The foam completely seals the door, preventing the passage of smoke and preventing oxygen from reaching the source of fire.

Dimensions

Depending on the type of seal, its dimensions also vary. Also the optimal size depends on the gap and how thick it is. The total footage also plays a significant role. door design, as well as features of the purpose of the door. For example, entrance doors require denser and wider insulation. Flexible rectangular profiles are sold in large rolls, the length of which depends only on the manufacturer. They are perfect for eliminating narrow gaps that do not cause much discomfort to the door owners.

In some cases, rubber profiles of complex configurations are used. They are suitable for ordinary doors, and even for super-heavy armored doors. Each of the profiles has its own special shape: C, P, O and so on. Each of the shapes is designed for gaps of a certain size, however, remember that these profiles are used to insulate gaps 1-4 mm wide, but some shapes are good for insulating larger gaps.

• Profiles of shapes C, K, E are suitable for masking small gaps, the size of which does not exceed 3 mm.
• Forms P and V will do an excellent job of masking cracks up to 5 mm.
• Less commonly used are profiles O and D, which allow working with gaps up to 7 mm.

When calculating required quantity flexible profile for door insulation, keep in mind that you will definitely need at least 5-6 m of material. It is always better to take a soft seal with a small reserve, since if suddenly part of the installed profile deteriorates, it can always be quickly changed. Rigid seals are made directly to the size of the door. As a rule, independent measurement and purchase causes certain difficulties, so it is better to turn to professionals with this issue. There is only one seal on the market that requires such delicate selection - this is the magnetic version.

Seals also vary in thickness. Soft thin profiles are selected for interior doors, while entrance doors require more impressive insulation. Thick rubber profiles, often multi-layered, have impressive dimensions compared to miniature interior samples. Thus, when selecting a seal of the required size, it is imperative to focus not only on the type of seal, but also on functional purpose insulated door, to the size of the existing gaps. Pay attention to where the element will be attached: along the perimeter of the door frame or directly on the door leaf. Traditionally, thicker options are mounted on the door frame than on the door itself, since when installed on the door frame there is little risk that the door simply will not close.

Which seal material is better?

On this moment There is a huge range of materials from which door seals are made. After reviewing the characteristics of each of them, you will be able to determine exactly which option is right for your case.

• Rubber The seal is perhaps the most popular today. This is due to the versatility of the material, since it tolerates temperature changes, high humidity and other negative influences well. To prevent bacteria from multiplying at the joints or fungus from appearing, the rubber is pre-treated with a special compound that prevents the activity of bacteria and disinfects the surface.
• Silicone option - good alternative rubber seal. Silicone is mainly used for insulating glass doors, since it sticks tightly to the glass, you just need to moisten it with water and let it dry. Silicone does not crack under the influence of strong temperature changes and does not come off the glass. Silicone elements are much better than rubber ones; they are suitable for rooms with high humidity, such as baths, saunas, and bathrooms.

• A special place is occupied by modern TEP seals. They are distinguished by their ability to adapt to extremely high or extremely low temperatures. Sometimes the spread can be more than 100 degrees – from -70 to +95 degrees Celsius. The European formulation of thermoplastic elastomer guarantees high reliability, long service life, good resistance to impact loads, and low profile deformation during operation.
• Felt is the most traditional and familiar material from childhood. Due to the fact that felt is still made from natural wool, it protects the room well from the cold and is on the list of leaders largely because of this. During its entire service life, felt insulation does not lose its original properties, withstands harsh Russian weather conditions well, and conserves heat. Contrary to popular belief, felt is completely fireproof because it has a very dense structure, which makes it difficult to burn.

What colors are there?

Today, seals are produced in bulk color solutions, which include not only the classic black or white colors. It is possible to choose the necessary model for a door of any shade, be it a balcony plastic sample white or a bright door to the nursery. However, it is the white and black options that enjoy the greatest success among consumers. White models are mainly matched to plastic doors when owners need to decorate some cosmetic flaws. Also, white seals look good on interior designs, while on the front door a white element is unlikely to look appropriate.

For the front door, on the contrary, black insulation is the best solution. Black models go well with almost all types metal doors, and this fact should be taken into account. In addition, painted rubber insulation for entrance doors performs its functions worse, since paint significantly changes the chemical composition of the material. The same can be said about plastic balcony doors. It is best to choose a black seal, it will protect as much as possible. living rooms from the draft outside.

There are a great variety of color models. There are no texture swatches or patterned options, but the color choices are virtually unlimited. The entire range of brown shades is the most popular, since seals are often selected for wooden doors, and people try to choose them so that they are as invisible as possible. door leaf, did not spoil the overall impression. Please note that they often offer to immediately equip the door with a suitable seal for a relatively small fee. desired color. As a rule, this option is more preferable, especially if you know in advance that you need to install such a kind of plug for the cracks. The decision to buy a door with a ready-made sealing element will greatly save you the effort and time that you would spend on searching, and will not hit your budget too much.

Whatever color seal you choose, remember that general form rooms and doors individually should remain harmonious, however, it is much more important that the selected sample copes well with its main functions.

What are they fastening with?

There are several options for attaching seals. Each of them is determined by the type of fastening with which a specific option is equipped.

• Installation in groove. The profiles for fastening into the groove are equipped with a special fastening brush. You won't need any for installation. Additional materials However, this does not make the installation of such elements the easiest. The main difficulty that most people have when working with groove seals is fitting them to required size. It should be understood that rubber is a material that stretches easily and just as easily takes on its original shape, so when cutting or pressing directly into a groove, you cannot pull the product out; on the contrary, you should “gather” it a little. Trimming groove seals should be carried out after they have been installed in place, otherwise there is a high risk of cutting off the excess, and this will inevitably negate the entire effect that was planned to be achieved through the installation of the elements.

• Self-adhesive option. Installation using self-adhesive tape is usually the least difficult. As in the previous case, the only equipment you will need is a paint knife, which, after gluing, you need to cut the insulation to the desired length. The most important place in the preparatory process is occupied by surface preparation: it must not only be well cleaned of dirt and dust, but also thoroughly degreased. Traditionally, the tape is glued from left to right and from top to bottom, that is, on the sides, pasting must be started from the top corner. Gradually, little by little, the sticky side of the seal is removed protective layer, the tape, without stretching, is fixed on the surface and only after it has been completely secured can you again release a little of the adhesive tape and fix it further. The step is approximately 10 cm.

• On nails or screws. This option has not been particularly popular lately, since it is a good alternative to nails. adhesive tape or glue. In some cases, it turns out to be impossible to install a self-adhesive sample (for example, if the surface is uneven or the seal is too heavy), and then traditional nails are remembered again. The distance between the nails is 5-7 cm; installing fasteners less frequently is not recommended, as sagging may occur, through which water will enter the room. cold air. When installing insulation on screws or nails, you need to act very carefully, since if the caps are not deepened enough, the door will close with difficulty or not at all. This option is mainly suitable for entrance doors, but in the case of interior doors, it is better to do without a seal at all than to choose fastening with nails.

How to choose the right door insulation?

• For a wooden door in a log house, a good solution would be to use silicone insulation. Pay attention to how easy it is to replace one model with another. Wooden houses Over time, they “settle”, and after a few years, the door will be difficult to close, and then it will be necessary to replace the existing sample.
• For wooden doors in ordinary houses, the installation of mortise seals, which are almost invisible against the background of the door, is very popular. If possible, it is recommended to choose this contour option, as it will provide you good sound insulation, and if the door dries out, the seal can be simply removed without harm to aesthetics.
• You definitely need to select a seal that matches the tone of the door structure so that it looks as organic as possible against the general background and does not spoil the whole look.

How to attach the door seal, see the video below.

To provide additional sound insulation, any metal doors require the installation of a seal. This article will tell you how to choose and correctly install a high-quality seal for metal doors.

General concept and functions of a seal for a metal door

The seal is a hardware element of a metal door. The main function of the seal is to protect the room from extraneous sounds. Additional functions seal:

• protecting the premises from foreign odors;
• thermal protection - preventing the formation of drafts;

• sealing - ensuring a tight fit of the door leaf to the door frame.

Let's consider the basic requirements for a high-quality seal for a metal door:

• the seal must ensure complete tightness, the door protects the room from the entry of extraneous noise, moisture, cold air, small dust particles or strong odors;
• the seal ensures reliable and smooth closing of the door;
• the seal must meet high standards that ensure water and air tightness and excellent shock-absorbing properties of the metal door;
• the seal eliminates the sharp unpleasant sounds that a metal door makes when closing; after installing the seal, the door closes softly and silently;
• the seal for a metal door must be resistant to sudden temperature changes to avoid hardening or peeling off;
• the seal should interact well with the door, there should be no gaps when closing;
• ensuring fire safety: using a rubber contour to trap cold smoke, using a thermally expanding layer to fill cracks and prevent the spread of fire.

Types of seals for metal doors

Depending on the type of material, sealants are divided into:

• rubber,
• silicone,
• polyurethane,
• plastic,
• foam rubber.

The rubber seal for a metal door is characterized by durability and endurance.

Advantages of installing a rubber seal on a metal door:

• high level of air and moisture resistance;
• resistance to prolonged exposure to precipitation, temperature changes, and ultraviolet radiation;
• long service life;
• low cost;
• no cracking.

Rubber seals are made from oil-resistant, acid-resistant rubber, which is food grade or high-tech grade.

Silicone seals, which are excellent for metal doors, are not inferior to rubber ones. The advantage of a silicone seal is that silicone does not emit harmful substances and ensures the environmental safety of the home. Silicone does not provoke allergies, which is why such seals are installed on metal doors in children's or medical institutions.

The polyurethane seal is easily attached to the door, as it has a self-adhesive film on one side. Plastic seals Rarely installed on metal doors, just like foam rubber ones. Although the cost of these seals is quite low, the quality characteristics do not allow them to be used on a metal door for a long time.

In relation to the design and type of fastening, seals are divided into:

• magnetic seal for metal doors;
• seal with an additional clamping mechanism;
• The seal for metal doors is self-adhesive.

The magnetic seal appeared not so long ago, but is increasingly used in the manufacture of metal doors from the manufacturer. Magnetic seals are installed on refrigerator or freezer doors. The operating principle of the seal is based on the attraction of permanent magnets using attraction poles. A triple circuit magnetic seal is installed on metal doors. The first two circuits are located directly on the door, and the third - on the door frame. Magnetic seals have a drawback: if there is a strong attraction of magnets, such a door will be difficult to open for a child or an elderly person, and if there are weak magnets, the door will not meet all the requirements for sealing and sound insulation.

It is better to install a magnetic seal on metal doors that do not have decorative elements, but consist of ordinary sheets of metal. The magnetic seal has two components: a soft part and a magnetic insert. The soft part is made of thermoplastic elastomer. Advantages of using thermoplastic elastomer:

• aging resistance;
• operating temperature from -65 to +90 °C;
• After use, this material is recycled.

1. When choosing a self-adhesive seal, be sure to check the expiration date of the adhesive that is applied to one side of the tape.

2. Do not use foam seals on a metal door. After all, as a rule, a metal door is used at the entrance to a room and has the greatest load in terms of the number of openings; in this case, foam rubber will deteriorate very quickly.

3. Before giving preference to a particular seal, carefully study the information about materials, shelf life and technical features seal.

4. To check the sealing properties of the seal, you should press the seal slightly; if the material quickly regains its shape, the seal will provide a good seal.

5. When choosing a seal that requires additional gluing, buy good quality silicone glue.

6. Pay attention to the color of the seal, in most cases it is black, brown or white, but there are exceptions and some companies allow you to choose the color individually to match the color of the door.

7. When choosing a seal for a metal entrance door, you should not focus on the color variety, since paint significantly affects the quality characteristics of the seal; it is better to choose a standard black seal.

8. The rubber seal should be of medium hardness, too soft material It will quickly become unusable, and a seal that is too hard will prevent the door from closing.

9. When choosing a self-adhesive sealant, the sticky side should be covered with small particles of fiberglass.

Rules for selecting a seal for a metal door

Before you buy a seal for metal doors, you should decide on the shape and type of seal. Seals are sold in in roll form with medium length tape 600 cm, for a standard door this seal will be enough.

To choose the right seal, you need to measure the gaps of the metal door. For this procedure, take plasticine, which needs to be wrapped in polyethylene and insert it into the slot, when closed door. Use a tape measure or ruler to measure the length of the gap.

For a gap that ranges from 1 to 3 mm, use a rectangular foam rubber, polyethylene foam or polyvinyl chloride sealant.

For gaps that exceed 3 mm, rubber seals are used, which are divided into:

• seals with a C-shaped, K-shaped or E-shaped profile - used in three-millimeter gaps;
• A P-shaped or V-shaped seal is used to close a gap with a thickness of 3 to 5 mm;
• in gaps that exceed 5 mm, install an O-shaped or D-shaped seal.

When replacing a seal, you should tear off a piece of the old seal and select a new seal that is as similar in size as possible in the store.

To determine the size of the required seal, decide on the number of layers, and then measure the dimensions of the metal door and determine the perimeter of the door frame, multiply the resulting number by the number of layers. It is better to purchase a seal with a reserve.

Installing a seal on a metal door

1. When replacing the seal, you should thoroughly clean the surface of the doors from the old seal with fine sandpaper and wash the doors well with an acetone or alcohol solution.

2. Metal doors are used at the entrance to a room, so it is advisable to install two or three layers of sealing to ensure a more reliable seal.

3. When installing a seal on the front door of an apartment that does not face the street, install two layers of seal. Place the first layer on the outer door leaf, and install the second layer on the door frame.

4. If the seal is installed on a metal door that opens directly onto the street, it is better to lay three layers of seal. The first and second circuits are installed on the door frame and the inside of the door, and the third - on the outer surface of the door. Requirements for an external seal for a metal door: resistance to temperature changes, ultraviolet radiation, moisture, precipitation, good dimensional stability and tightness.

5. When purchasing branded doors from the manufacturer, a seal is present on such doors. If there is a double door sash, the seal is located on each sash.

6. The rubber seal is installed using silicone glue. To do this, the seal is gradually coated with glue and applied to the surface of the door.

7. When installing a seal on a painted metal door, at least twenty days must pass from the moment of painting.

Installation of self-adhesive seal

Before replacing the seal, you should clean the surface from any remnants of the old seal and wipe the doors with an acetone-containing solution.

A self-adhesive seal is even easier to install than a rubber seal. To install, you need to gradually, removing the tape, glue the seal around the perimeter of the door leaf. If the seal begins to hold poorly over time, use glue or sealant for gluing. When replacing the seal, do not use separate pieces, as there is a risk that the seal will not perform its sealing function properly. Pay attention to the sealing of the corners, as in these places the seal may wrinkle or adhere poorly. After the seal is completely glued, trim off the remaining parts with scissors.

The level of protection of the house from street noise and cold is affected not only by the quality of the entrance doors, but also by the material that helps them fit tightly to the frame. The absence of cracks creates a good seal, preventing drafts from spreading: in this case, sounds and smells from the outside will not be able to penetrate inside the house.

The classification of materials for door seals is carried out according to some basic characteristics. It's about first of all, about the dimensions, material of manufacture and types of doors for which this seal was developed.

For example, wooden and iron doors are decorated with different types of ribbons, although they are very similar in appearance. To choose the right equipment for your door, it is important to navigate this classification.

Sealing strips by door type

For each individual variety, its own seal was developed.

Input

Most often, entrance doors are finished with a dense material in the shape of a tube, inside of which there is a void. The significant thickness and bubble nature of the material create a reliable fit of the door to the frame. How to choose reliable and warm doors to your home.

Of particular interest is the internal structure of these rubber bands for insulating doors. Thanks to the presence of internal pores, a multiple increase in the insulating effect is achieved. Most often, the entrance door seal has a self-adhesive base, which makes its installation very quick.

On the other hand, over time, the glue loses its characteristics, and the strips begin to lag around the perimeter. You can.

Interior

The seal for interior doors is not assigned the function of protecting the room from outside cold, as in the previous case.

This allows you to make it more aesthetically pleasing by using more elastic and soft silicone instead of dense rubber. The installation method for these products may differ, which will be discussed below.

If you decide to change the doors during the renovation process, be sure to read.

Plastic

This group of materials is characterized by high speed of installation and dismantling. Grooves are usually applied to plastic doors along the line of contact with the frame, so the seals are given a special shape that follows the configuration of these grooves. Due to the presence of walls on the sides of the fixation point, the sealing strip receives additional protection from external aggressive influences. The seal for plastic doors is not afraid of moisture and temperature changes, so it can be used both outdoors and on interior doors without much difference. It is important to keep in mind that this rubber seal was designed specifically for plastic doors with grooves, so it is not recommended to seal other types of doors with it. In addition, different manufacturers complete their plastic doors with an individual seal: this should also be clarified when selecting a suitable material.

Glass

In the manufacture of seals for glass doors, silicone is used, equipped with a special profiled notch. When installing the strip, you must first wet the area where it will be placed: this will make the connection as strong as possible. Since the design of glass doors can be very different, therefore, a different seal is developed for each of them.

What is door insulation made of?

In order to choose the most suitable door seals for your home, you should also be aware of the materials used to make them.

Rubber

Most often, entrance doors are equipped with a rubber seal. Moreover, the manufacturing material is not simple rubber, but its modified varieties that can withstand the most extreme conditions operation, including severe frost and the heat. In addition to the draft.

Silicone

The performance characteristics of silicone products are slightly lower than those of rubber products. This is explained by the fact that it is not possible to provide silicone with additional resistance to aggressive external influences even by introducing appropriate additives into its composition. For this reason, silicone liners are mainly produced for wooden interior doors that are used in comfortable conditions.

Foam rubber

It is the material used to manufacture the cheapest door insulation, which fails within one year. The reason for this may be temperature fluctuations, dirt and moisture, which provoke crumbling and disintegration of the foam rubber. The material gradually loses its original volume, which affects the functionality of products made from it.

Magnet

An innovative development, which is mainly used to complete expensive metal doors. The average person is familiar with the magnetic seal from household refrigerators and freezers, in which permanent magnets around the perimeter of the doors are attracted by attractive poles. Most often, metal doors are equipped with three-circuit magnetic seals. The location of the two circuits is the door leaf itself, while the third is mounted on the door frame. The main disadvantage of such products is the rather high pressing density, which a child or child will not always be able to cope with. old man. If the action of the magnets is weakened, then proper tightness and sound insulation will not be ensured.

Advantages of a magnetic door seal

The soft filler is made of thermoplastic elastomer, which has the following advantages:

• Significant service life.
• Stable tolerance of sudden temperature fluctuations (from -65 to +95 degrees).
• Possibility of recycling after loss of performance.

Felt

Usually they are formed with a felt seal. Such tapes cannot provide special protection from noise and cold. They are used exclusively to prevent dust from entering the cabinet or room.

Basic methods for installing door seals

When starting to install a door seal, the first step is to find out what type of product you are dealing with. This will allow you to choose the most optimal way to glue the seal. The most common types of rubber seals are grooved and self-adhesive.

Groove seals

The installation of this material is very simple, which is why it is most often used for self-repair doors. The most difficult part of installing the door seal into the groove is finishing the corner areas. Beginners are advised to use careful trimming of the material. More experienced users achieve continuous laying, without joining areas. The latter option is more advantageous, since the level of door sealing in this case is much higher. However, to implement it you will need to show some skill. Door seals at the bottom are equipped with a special edge on which there is a brush: this structure of the material facilitates fairly quick installation into the groove cavity.

While laying both rubber and silicone seals, it is important to avoid even minimal tension on the tape. Otherwise, unacceptable stress will form inside the sealing layer, which will affect its performance. No matter how high-quality the silicone or rubber is, they will gradually stretch, losing their original volume and elasticity. Experienced craftsmen When laying the seal in the groove, try to slightly compress it, which significantly extends the service life of the door insulation. Trimming of excess parts is carried out upon completion of installation. It is more convenient if only one edge of the rubber or silicone tape is left for trimming: in this case, the remaining segment is longer and can be used to insulate another door.

Self-adhesive seal

Laying such material is also not particularly difficult, although there are some useful tips should be taken into account. In order for the self-adhesive rubber seal to stick to the seat efficiently and for a long time, it should be pre-prepared. This procedure includes several steps. Firstly, all dirt must be removed from the surface of the door: this is done not only along a narrow installation area, but by some expansion to the sides. For these purposes, soapy water or detergent is usually used.

Preparation will require special care wooden surface. You should not moisten it too much - just wipe thoroughly with a damp cloth. If seat has roughness, protrusions and irregularities, they need to be eliminated. In this case, the operating technology also depends on the surface material. For example, wood can be lightly sanded and puttied; For metal or plastic surfaces, gentle sanding will be sufficient. Individual protrusions can be carefully removed with a chisel or sandpaper. After the sealing area has been cleaned and washed, it should be completely dry. Sometimes, if the work is carried out in a confined space, or when it is necessary to speed up the process, a regular hairdryer is used for drying.

Before gluing the seal to the door, it must be degreased. When choosing a degreasing agent, it is important to consider the surface material. Most often, this procedure is carried out with white spirit, acetone or regular alcohol. However, it should be understood that all of these products are toxic and explosive, and you should work with them very carefully. It is better if it is possible to ventilate the premises well after application.

Helpful advice: in cases where the seal is installed where people are present at the time, it is better to use a special low-toxic emulsion or an aqueous alkaline solution for degreasing.

As for the actual installation of the self-adhesive seal, this procedure is not particularly difficult. All you need to do is remove the bottom part of the material from the protective film and carefully lay it along the edge of the door. It is more convenient to remove the entire film not at once, but in 10-15 cm segments, immediately installing the freed area on the seat. At the same time, it must be pressed tightly against the surface of the door, achieving high-quality adhesion. A similar algorithm of actions is maintained throughout the entire procedure. It is more convenient to start work from the top, and when you reach the bottom edge of the door leaf, cut the rubber tape using a sharp knife or scissors.

The sealing tape has not only the function of protecting the home from drafts. In the fight against extraneous sounds coming from the street, the seal can also play an important role. When choosing, you should pay attention to several aspects: types of seals, the materials from which they are made, and also use tricks that will help you choose the right door insulation.

Functions

The most important function of the seal is protection from drafts. If a device cannot cope with this task, it is a priori of insufficient quality. This is especially true for entrance doors: thermal insulation in this case is extremely important, and only a sufficient level of insulation can ensure it. An important thermal insulation function “works” in both directions, simultaneously protecting the apartment from cold wind from the street or from the entrance and preventing heat from escaping from the home. It is estimated that doors that are not equipped with a seal release up to 40% of all the heat generated by heating appliances. Heating prices are currently quite high, so no one wants to waste precious heat.

Speaking about thermal insulation, one cannot fail to mention that a number of products can withstand significant temperature fluctuations. The amplitude can vary from -65 to +95 degrees Celsius. Thus, by installing high-quality insulation on the front door, you don’t have to worry about it cracking in summer or winter.

Another advantage of the seal is its noise-insulating properties. They are inherent in both metal water doors and interior doors. It happens that the front door is right next to a road or a playground, and the insufficient level of sound insulation does not allow residents to feel comfortable enough, because annoying sounds from the street are very disturbing. If the rooms are not well isolated from each other, then another problem arises: the impossibility of everyone doing their own thing without the risk of disturbing the other. Good sound insulation makes situations comfortable when, for example, they play the piano in one room and read in another.

Shock absorption properties are another important factor. Everyone has encountered a situation where in the summer, due to open windows, drafts flow through the house, and the doors close with a strong bang, disturbing not only the residents of the house, but also their neighbors. The sealing tape conceals unpleasant sound, preventing the creation of annoying slams, and also extending the life of the door and door frame (due to sharp slamming, they wear out faster).

The seal protects the house well from unnecessary odors or smoke. For example, something may burn in the kitchen. No one wants the “aroma” of burning to instantly spread throughout all the rooms, so insulation will help keep the smell out only in the kitchen. The same can be said about the door to the bathroom: it is better to leave wet steam directly within the bathroom and not let it out into the hallway or corridor.

Thus, the main property that a door seal has is sealing the door leaf. In the Russian climate, this property of the door is extremely important due to strong temperature changes on the streets. Moreover, you should carefully consider the choice of product if you live in a large, noisy city, because many cities are very busy both during the day and at night. It is for such “sleepless” cities that doors with seals for enhanced sound insulation are well suited. When choosing a door to the kitchen, you also need to make it as airtight as possible, because it is not always appropriate and pleasant when food smells are heard, for example, in the bedroom.

Kinds

Seals are classified according to several criteria. The first of these is the type of door:

• For entrance doors. The door seal for entrance doors is usually made tubular. The profile with a cavity inside completely ensures a sufficient fit of the door, contributing to complete isolation from external influences.
• For interior doors. Here completely different requirements are presented: there is no need to protect the room so strongly from the environment; the aesthetic component comes first. In some cases, isolation is important (for example, in the bedroom), but not required.
• For plastic doors. Seals for plastic doors are placed in a separate category, since they differ significantly from seals for ordinary doors. It is necessary that the groove element reacts well with the environment. As a rule, such seals are installed on balcony doors. Please note that, as a rule, only a part that is produced by the same manufacturer as the door itself is suitable for a plastic door.
• For glass doors. The profile, which is attached directly to the glass, can be aluminum or silicone. Silicone elements must have a special cross-section; they also serve as insulation, while an aluminum profile must have a special rubber seal. A silicone glass seal is suitable for rooms with high humidity, since there is no risk that it will “come off”.

Based on materials, the following types are distinguished:

• Rubber.
• Silicone.
• Foam rubber.
• Magnet.
• Thermoplastic.
• Felt.

According to the configuration, the following types are distinguished:

• Tape. It is a soft cord with a rectangular cross-section, the width of which is approximately 9 mm.
• Tubular. Despite the fact that a tube seal is most often used for entrance doors, it boasts less sealing properties than tape models. It is a hollow tube inside, which is pressed when closing the doors, due to which there are no gaps between the door leaf and the frame.
• Groove. Made specifically for plastic doors, it is a hollow profile made of soft rubber, on one side of which there is a special brush installed in the grooves. Thus, the impact of the external environment on the seal is reduced and is almost completely transferred to the door leaf itself.

• Spring-loaded. Attaches to the door frame, not the door. When closing, its parts slide along the spring and close the cracks. Suitable only for fastening on perfectly flat surfaces.
• Mortise. Made for wooden doors. A small niche is specially cut out in the door frame for such a seal, which allows the door leaf to be tightly fitted in the future. A rubber profile is attached to the niche.
• Folding. Suitable for sealing folding doors, folding doors and similar structures.

Tape seals are rarely made wider than 10 mm. This is due to the fact that this width is optimal both for attaching around the perimeter of the door leaf and for the door frame. Tubular options generally have the same characteristics, regardless of what material they were made from. The size of the seal for a plastic door depends entirely on the manufacturer. It often happens that for each specific door model only one single model of seals is suitable, and there is no way to replace it with an analogue. It is recommended to pay special attention to this issue when choosing a door, whether it is possible to replace parts with those purchased from another manufacturer, otherwise during repairs you may need to replace the entire door.

A complex rubber profile remains a universal choice, suitable for both interior and entrance doors. It is available in various versions, can be made of soft rubber or more dense, the width of the profiles is traditionally 8-10 mm.

• Foam rubber It is better not to use the element for entrance doors and save it for interior structures. The fact is that foam rubber is not the most durable material and will simply not withstand the kind of use that the front door is subjected to. Foam rubber is quite cheap, but it copes well with the basic functions of the seal. It is best to use foam inserts for doors that are subject to little use, for example, to a living room.
• Unlike foam rubber, magnetic constructs are used only for entrance doors. Magnetic inserts on soft rubber profiles guarantee the best sealing fit, so protection against drafts or heat leakage from the house is guaranteed. Problems can only arise with the installation of the elements; they must be selected exactly to the size of the door, otherwise the magnetic protrusion simply will not allow the door to close.

Another current option is colorless insulation. Many people believe that they are a good solution only for glass doors, however, this is far from the case. The transparent seal looks great on wooden, plastic, and metal doors, since it is practically invisible. Thus, it can be used in cases where the owner is afraid of spoiling the aesthetic appearance of the door or if, from a stylistic point of view, the use of a seal is inappropriate.

According to texture, the following types are distinguished:

• Flexible. Smooth or flexible profiles can be made of many different materials, including rubber, silicone, magnet.
• Liquid. Usually used when insulating entrance doors. It is some semblance of liquid foam rubber, which is applied to the desired areas under pressure.
• Pile. The fleecy option is very familiar to many, since felt was originally the only alternative for making door insulation. At this stage of development of the repair business, they produce a harness and tape not only from pure felt, but also from synthetic fleecy fabric.

The following options are available by location:

• Threshold. They are a good solution in cases where the door design does not provide for a threshold. It is mainly done using automatic control, which allows the profile to “adjust” to the width of the gap between the door and the floor in the open or closed position.
• Contour. Outline options are the easiest to understand. They are attached along the entire perimeter of the door leaf or frame, simultaneously eliminating cracks everywhere. Most often used for entrance doors, a triple profile is used.
• Firefighter. This thermally expanding option is a substance that turns into foam when heated strongly. The foam completely seals the door, preventing the passage of smoke and preventing oxygen from reaching the source of fire.

Dimensions

Depending on the type of seal, its dimensions also vary. Also the optimal size depends on the gap and how thick it is. The overall size of the door structure, as well as the specific purpose of the door, also plays a significant role. For example, entrance doors require denser and wider insulation. Flexible rectangular profiles are sold in large rolls, the length of which depends only on the manufacturer. They are perfect for eliminating narrow gaps that do not cause much discomfort to the door owners.

In some cases, rubber profiles of complex configurations are used. They are suitable for ordinary doors, and even for super-heavy armored doors. Each of the profiles has its own special shape: C, P, O and so on. Each of the shapes is designed for gaps of a certain size, however, remember that these profiles are used to insulate gaps 1-4 mm wide, but some shapes are good for insulating larger gaps.

• Profiles of shapes C, K, E are suitable for masking small gaps, the size of which does not exceed 3 mm.
• Forms P and V will do an excellent job of masking cracks up to 5 mm.
• Less commonly used are profiles O and D, which allow working with gaps up to 7 mm.

When calculating the required amount of flexible profile for door insulation, keep in mind that you will definitely need at least 5-6 m of material. It is always better to take a soft seal with a small reserve, since if suddenly part of the installed profile deteriorates, it can always be quickly changed. Rigid seals are made directly to the size of the door. As a rule, independent measurement and purchase causes certain difficulties, so it is better to turn to professionals with this issue. There is only one seal on the market that requires such delicate selection - this is the magnetic version.

Seals also vary in thickness. Soft thin profiles are selected for interior doors, while entrance doors require more impressive insulation. Thick rubber profiles, often multi-layered, have impressive dimensions compared to miniature interior samples. Thus, when selecting a seal of the required size, it is imperative to focus not only on the type of seal, but also on the functional purpose of the insulated door, on the size of the existing gaps. Pay attention to where the element will be attached: along the perimeter of the door frame or directly on the door leaf. Traditionally, thicker options are mounted on the door frame than on the door itself, since when installed on the door frame there is little risk that the door simply will not close.

Which seal material is better?

At the moment, there is a huge range of materials from which door seals are made. After reviewing the characteristics of each of them, you will be able to determine exactly which option is right for your case.

• Rubber The seal is perhaps the most popular today. This is due to the versatility of the material, since it tolerates temperature changes, high humidity and other negative influences well. To prevent bacteria from multiplying at the joints or fungus from appearing, the rubber is pre-treated with a special compound that prevents the activity of bacteria and disinfects the surface.
• Silicone option is a good alternative to a rubber seal. Silicone is mainly used for insulating glass doors, since it sticks tightly to the glass, you just need to moisten it with water and let it dry. Silicone does not crack under the influence of strong temperature changes and does not come off the glass. Silicone elements are much better than rubber ones; they are suitable for rooms with high humidity, such as baths, saunas, and bathrooms.

• A special place is occupied by modern TEP seals. They are distinguished by their ability to adapt to extremely high or extremely low temperatures. Sometimes the spread can be more than 100 degrees – from -70 to +95 degrees Celsius. The European formulation of thermoplastic elastomer guarantees high reliability, long service life, good resistance to impact loads, and low profile deformation during operation.
• Felt is the most traditional and familiar material from childhood. Due to the fact that felt is still made from natural wool, it protects the room well from the cold and is on the list of leaders largely because of this. During its entire service life, felt insulation does not lose its original properties, withstands harsh Russian weather conditions well, and conserves heat. Contrary to popular belief, felt is completely fireproof because it has a very dense structure, which makes it difficult to burn.

What colors are there?

Today, seals are produced in a variety of colors, which include not only the classic black or white. It is possible to choose the necessary model for a door of any shade, be it a white balcony plastic sample or a bright nursery door. However, it is the white and black options that enjoy the greatest success among consumers. White models are mainly matched to plastic doors when owners need to decorate some cosmetic flaws. Also, white seals look good on interior designs, while on the front door a white element is unlikely to look appropriate.

For the front door, on the contrary, black insulation is the best solution. Black models go well with almost all types of metal doors, and this fact should be taken into account. In addition, painted rubber insulation for entrance doors performs its functions worse, since paint significantly changes the chemical composition of the material. The same can be said about plastic balcony doors. It is best to choose a black seal; it will maximally protect living rooms from drafts from the outside.

There are a great variety of color models. There are no texture swatches or patterned options, but the color choices are virtually unlimited. The entire range of brown shades is the most popular, since seals are often selected for wooden doors, and people try to choose them so that they are as invisible as possible on the door leaf and do not spoil the overall impression. Please note that they often offer to immediately equip the door with a suitable seal in the desired color for a relatively small fee. As a rule, this option is more preferable, especially if you know in advance that you need to install such a kind of plug for the cracks. The decision to buy a door with a ready-made sealing element will greatly save you the effort and time that you would spend on searching, and will not hit your budget too much.

Whatever color of seal you choose, remember that the overall appearance of the room and the door separately should remain harmonious, however, it is much more important that the selected sample copes well with its main functions.

What are they fastening with?

There are several options for attaching seals. Each of them is determined by the type of fastening with which a specific option is equipped.

• Installation in groove. The profiles for fastening into the groove are equipped with a special fastening brush. For installation you will not need additional materials, however, this does not make the installation of such elements the easiest. The main difficulty that most people have when working with groove seals is adjusting them to the required size. It should be understood that rubber is a material that stretches easily and just as easily takes on its original shape, so when cutting or pressing directly into a groove, you cannot pull the product out; on the contrary, you should “gather” it a little. Trimming the groove seals should be done after they have been installed in place, otherwise there is a high risk of cutting off the excess, and this will inevitably negate the entire effect that was planned to be achieved through the installation of the elements.

• Self-adhesive option. Installation using self-adhesive tape is usually the least difficult. As in the previous case, the only equipment you will need is a paint knife, which, after gluing, you need to cut the insulation to the desired length. The most important place in the preparatory process is occupied by surface preparation: it must not only be well cleaned of dirt and dust, but also thoroughly degreased. Traditionally, the tape is glued from left to right and from top to bottom, that is, on the sides, pasting must be started from the top corner. Gradually, little by little, the protective layer is removed from the sticky side of the seal, the tape, without stretching, is fixed on the surface, and only after it has been completely secured can a little of the adhesive tape be released again and fixed further. The step is approximately 10 cm.

• On nails or screws. This option has not been particularly popular lately, since adhesive tape or glue is a good alternative to nails. In some cases, it turns out to be impossible to install a self-adhesive sample (for example, if the surface is uneven or the seal is too heavy), and then traditional nails are remembered again. The distance between the nails is 5-7 cm; installing fasteners less frequently is not recommended, as sagging may occur, through which cold air will enter the room. When installing insulation on screws or nails, you need to act very carefully, since if the caps are not deepened enough, the door will close with difficulty or not at all. This option is mainly suitable for entrance doors, but in the case of interior doors, it is better to do without a seal at all than to choose fastening with nails.

How to choose the right door insulation?

• For a wooden door in a log house, a good solution would be to use silicone insulation. Pay attention to how easy it is to replace one model with another. Wooden houses “shrink” over time, and after a few years, the door will be difficult to close, and then it will be necessary to replace the existing sample.
• For wooden doors in ordinary houses, the installation of mortise seals, which are almost invisible against the background of the door, is very popular. If possible, it is recommended to choose this contour option, as it will provide you with good sound insulation, and if the door dries out, the seal can be simply removed without harm to aesthetics.
• You definitely need to select a seal that matches the tone of the door structure so that it looks as organic as possible against the general background and does not spoil the whole look.
