The front door in an apartment is a boundary, upon crossing which we find ourselves at home or return to the outside world. This border protects our property from thieves, prying eyes and uninvited guests, but not every door can protect your home from noise. Soundproofing front door will correct this annoying misunderstanding with his own hands.

Soundproofing of a metal entrance door - features

The most expensive and quick way to get a soundproof apartment - buy a ready-made multi-layer door structure. High-quality entrance doors are somewhat similar to sandwich panels - inside they have several layers of soundproofing materials that both absorb sound and dissipate it.

A first class soundproof door can cope with the sounds of the city at night - it is enough to prevent sound waves of up to 30 dB, characteristic of nightlife, remained outside the threshold. True, daytime noise will still reach the apartment residents. Doors with increased sound insulation can also cope with the sounds of daytime bustle, which exceed 40 dB.

The disadvantage of such products is their high price, which is often completely unjustified. And ordinary metal doors not only do not stop the sound, but also amplify it. Nice doors for old women to eavesdrop on the details of their neighbors’ lives, but not for young families with children who will easily wake up to the sounds of a noisy front door.

In addition, an empty metal structure serves as an excellent heat conductor, so don’t be surprised if it also becomes cold in the hallway after installing it. Therefore, soundproofing a metal entrance door in an apartment is a doubly beneficial event, because you will also insulate it with your own hands.

Materials for door sound insulation - a wide choice

Various options will help you leave all the sounds of a noisy city outside the hallway; fortunately, today’s choice allows you to organize a real war against extraneous sounds. In general, everyone construction material It has, albeit a small, coefficient of absorption or dispersion of sound. The basic principle of sound insulation states that the passage of a multilayer structure is like death for sound waves, therefore, the more you manage to apply different materials, all the better.

To begin with, ensure sound insulation of the cracks around the perimeter of the door - for this there are such rubber seals, and special drop-down thresholds that change their position when closing/opening. Mineral wool has the highest sound absorption coefficient; moreover, it is an excellent insulation material and is completely non-flammable. Its only drawback, especially relevant in conditions of constant movement, is its tendency to shrink..

However, preventing subsidence is not so difficult by installing additional stiffeners inside door design. It is better not to use glass wool for insulating an apartment, since microscopic fibers can become airborne and settle in the lungs, causing irritation and coughing. Ordinary polystyrene foam is a cheap and accessible layer, moreover, it is easy to work with, but it absorbs sound much less effectively.

And the fire safety of the material leaves much to be desired. It should not be used as a sound absorber - it is an excellent sealant and insulation, but the sound-absorbing qualities are not up to par. In this case, you will need various self-adhesive vibration and noise insulators, such as bimast, splen, vibroplast. On standard sizes For a door, four sheets of these materials will be enough.

Soundproofing process - stuffing the doors!

You don’t need any special tools to soundproof your entrance doors yourself. An ordinary screwdriver, scissors and a knife will suffice. And you can find the necessary soundproofing materials in any decent building materials store. Of course, you can get by by gluing self-adhesive sound insulation directly to the surface of the door on both sides, but if you still care about the appearance of the product, then you will have to place all the layers of materials inside. By the way, it is also more effective.

If you are determined to disassemble the structure, you can at the same time stuff it with all sorts of electronic devices: peephole, lock.

So, you have disassembled the door frame. To begin, cover the inside of the doors with self-adhesive vibration and sound insulators. By the way, for good quality When gluing, the temperature of the door surface must be at least 20 °C. Then fill the remaining space with mineral wool or foam rubber. To prevent materials from settling, create additional stiffeners from scraps of tin or wood. Calculate the amount of materials so that they rest against the surface - this will prevent them from becoming loose. Having assembled the door frame, you will feel a huge difference, both in the level of thermal insulation and in the silence in the room.

Personal life in silence - soundproofing interior doors

We usually start thinking about the need to soundproof doors when the need arises. For example, adults want to watch TV, but children in another room need to learn homework. Metal structures are practically not used as interior doors - they are expensive and not practical. Most often, solid wood, fiberboard or plastic with glass inserts are used for this. By the way, glass significantly increases the penetration of sounds into the room, so this decorative element better to get rid of it.

Hollow doors made of chipboard or plastic also do not reduce the volume of sounds - they can act as resonators. The highest soundproofing properties wooden doors, but they are far from perfect. In a word, you can’t do without high-quality sound insulation.

In the case of hollow doors, the problem is solved in the same way as with entrance doors - we disassemble the frame, fill it with several types of materials, and assemble it again. But doors made of solid wood will have to be sheathed to improve sound insulation, preferably on both sides, or at least on the side where sounds penetrate. Faux leather or thick fabric, and to fill the space between the casing and the door, foam rubber, padding polyester or mineral wool residues from the soundproofing of the entrance doors. If the doors have glass inserts, it is better to get rid of them by covering the voids with sheets of plywood.

It is best to remove the doors from their hinges for cladding, otherwise every blow with a hammer on a furniture nail will sound like thunder. After laying them on the floor, nail the top edge of the trim first so that the fabric or leather can be stretched around the perimeter. It is advisable that you have an assistant in this matter.

When placing soundproofing materials under the sheathing, gradually move from top to bottom. This way you will be able to evenly distribute the sound insulation around the perimeter of the doors and stretch the upholstery well. Along the perimeter door frame it is also necessary to glue a seal, for example a hollow rubber profile cord, and install a threshold under the door.

There are not many differences between soundproof doors and their conventional counterparts, and in most cases they are expressed in some design features. In general, any, even the most shabby interior door is soundproofing - depending on the material from which it is made and some structural elements, the door can cope with noise of one level or another. This noise power, scientifically called the level, is measured in Decibels - it is about them, or rather how to reduce their number, that will be discussed in this article. Together with the site, we will look at the question of how to do the soundproofing of doors with your own hands?

Soundproofing the entrance door

Soundproofing doors: why does the door block let sound through?

Soundproofing of an entrance or interior door is fully ensured by three factors.

In principle, a reliable solution to the question of how to soundproof a door requires the presence of all three of the above factors - the absence of one of them reduces the ability of the doors to prevent noise penetrating from outside. It is these points that you need to pay attention to when approaching the issue of soundproofing a door with your own hands.

How to soundproof a metal entrance door

There is no point in reinventing the wheel - all the materials and technologies that allow high-quality soundproofing of the front door have long been known to people, and only the laziest do not use them. Among these widespread ways to make entrance doors quieter, there are several main ones.

• Upholstery or soundproofing material is a fairly old method and has been used, probably, since the invention of doors by man. It consists of installing a porous material on the door leaf that dampens sound waves, which can be padding polyester, foam rubber, cotton wool and similar porous structures. Such materials are simply glued on one side and the other. door leaf, after which, for decoration purposes, they are covered with leatherette, genuine leather and other similar materials. Other materials are also used for these purposes - for example, they dampen sound waves quite well wood paneling doors. MDF can serve as an analogue of this material.

  

• Seal the fit of the door leaf to the frame. This is the most important point in the process of soundproofing entrance doors - not only the ability to door block do not allow sound into the room, but also retain heat in the house. A loose fit of the doors is a guarantee of drafts, through which a lot of heat will evaporate from the apartment. To ensure a tight fit, rubber or foam rubber with a self-adhesive base are usually used - they are installed around the perimeter of the door leaf, in the places where it contacts the door frame. Best protection is ensured by installing two contours of such a seal - one tape is glued to the canvas, and the other to the box.
• Installation of a second door block. This decision can be called the most correct for one simple reason - air gap, formed between two door leaves, is at the same time a sound and heat insulator. In most cases the thickness outer wall in the area of ​​the doorway allows this to be done without any problems. Two technologies can be used here - in one case, the second door is simply added to the first, and in the other case, a double door block is installed, in which two door leaves have a common frame. The second option has more advantages - reliability, aesthetic appearance, and higher rates of heat and sound insulation.

  

In general, as in all other cases related to insulation and sound insulation of something, the greatest efficiency is achieved only when using integrated approach to solving these problems. Do you want almost complete silence? So, work with all three factors that ensure this characteristic of the door block.

How to carry out work on soundproofing the front door, see the video.

Soundproofing interior doors: how not to miss the main thing

The whole problem of complete soundproofing of interior doors lies in their decorative appearance - in fact, measures to insulate the door leaf are almost impossible. The only thing that can be done here is to replace the glass inserts (if, of course, they are available) with more deaf ones, and also to tighten the fit of the canvas to the box. In general, it is better to take care of the soundproofing of interior doors at the stage of their purchase and installation - it has already been said above that the presence or absence of a threshold plays an important role in this process. If it was not installed from the very beginning, then there is no possibility of adding it later - unless you decide to resort to complete dismantling of the interior door unit, remodeling it and installing it again.

What else can be added about the soundproofing of an interior wooden door is that this process will not make any sense if the walls of the room do not have proper sound insulation. This happens quite often when installing plasterboards. interior partitions– their thickness is incorrectly calculated, an insufficient amount of mineral wool is placed inside the partition and a vapor barrier is not installed. You understand that if the walls allow sound vibrations to pass through, then soundproofing the door will be of no use. There is even a joke about this. The commission at the construction site is checking the sound insulation of the walls - they approached the wall with different sides and one shouts with all his might: “Vasya, can you hear me?” Vasya responded: “Why are you yelling, I see you.”

This is how things stand with solving the issue of soundproofing doors - as you can see, everything is not so complicated, and most importantly, it is quite accessible for independent implementation. The only thing you need to remember is that everything needs to be done correctly, without violations or deviations from technology - otherwise it may turn out like in a joke. Do you want a quiet and peaceful apartment? Then take care of its complete soundproofing!

Making your home a place of peace and relaxation, a reliable refuge from the noise of the big city and the bustle of neighbors is not only possible, but also necessary. While there are many different articles about soundproofing walls and ceilings, there is less information about how to make doors soundproof.

Regardless of whether the doors are old or new, entrance or interior, you can always make them more noise-protective than they already are. Sound always travels through air, so the fewer acoustic bridges in the form of cracks and holes, the quieter the room will be.

Ideally, it is best to soundproof the door at the stage of its installation. But, if the doors are already installed, but the sound insulation is insufficient, then you can strengthen it.

A few points to consider:

• doorway trim;
• insulation of cracks around the perimeter of the door;
• glass installation density;
• Correct installation of handles and locks.

One of the sources of noise penetration is a poorly sealed door frame. If the installation is poor, not the entire perimeter is sealed, but only some of its sections. To make a soundproof opening, you need to more carefully insulate all openings. It is better to carry out alteration work during the next cosmetic renovation.

To soundproof the opening, you will need polyurethane foam or acoustic sealant, putty, and appropriate tools.

Sequence of actions if the door has been installed:

• take off decorative trims(If there are any);
• remove wallpaper, paint, plaster around the perimeter of the opening - everything that interferes with the work;
• remove dust from the surface;
• fill the gap between the walls and the door frame with insulating material;
• cut after drying soundproofing material according to the wall level;
• putty;
• install the trims in place.

It is better to soundproof the gaps between the door frame and the wall with sealant, as it will not displace the frame and better seals all the holes. But it happens that the gaps are too wide, then you have to use polyurethane foam. Then you need to carry out the work carefully: after applying the foam, close the door until completely dry, otherwise the box may “lead” and the door will not close.

Soundproofing cracks around the door perimeter

The most affordable door soundproofing is a sticker around the perimeter of the seal. Now in construction stores you can find self-adhesive seals different color and profile. It is better to glue them onto the door frame where the door leaf adheres. It is important to choose the correct thickness of the seal so that there are no problems with closing the door.

In interior doors, the weak point along the perimeter of the door leaf is the lower part. A sealant won't help there. This gap can be sealed, for example, using a foam roller attached to the door itself, but this solution does not look very good. It is better to initially install doors with minimum clearance below.

If soundproofing in a room is not needed all the time, but only, for example, while sleeping in the nursery, then you can get a special pillow that protects the baby from noise inside the apartment. It will also protect from drafts. Although this decision is rather forced.

Improving the insulation of the door leaf in places where glass and locks are installed

The sound insulation of interior doors will improve even if minor holes and cracks are removed. In interior doors with glass inserts, you need to pay attention to the tightness of the glass installation. It also happens that after changing locks or handles, small cracks remain, which also allow sound to pass through. For getting better sound insulation all these shortcomings need to be eliminated.

Do-it-yourself soundproofing of the front door

Soundproofing the doors leading to the entrance is the most common need, since while you can still somehow influence the noise level inside your apartment, you can’t change the sounds of footsteps from the stairs.

When solving the problem of soundproofing the front door, there are several options, which depend on what kind of door is installed. If it is wooden, then sound insulation of the door trim is required. And this can be done quite easily with your own hands.

The most simple solution To soundproof a wooden entrance door, it will be upholstered with a sheet of foam rubber and artificial leather. This method was relevant back in Soviet times and was used for soundproofing and thermal insulation of doors. Instead of foam rubber, batting or old blankets were more often used.

Now the meaning of such cladding remains the same, but, firstly, thanks to the color and texture variety of upholstery materials, the door will look much more aesthetically pleasing, and, secondly, real high-quality sound insulation will be used inside.

The best solution for soundproofing a wooden door is self-adhesive sheet materials. Materials designed for car sound insulation are well suited. For example, a vibration filter based on bitumen or splen is a self-adhesive foam material. You can also combine them.

Work option:

• remove the lock, handle, peephole - all protruding parts that interfere with the installation of sound insulation and upholstery;
• a vibration filter sheet is glued onto the grease-free and dust-free surface of the door (the dimensions of the sheet are 1 - 2 cm smaller than the door on each side - this distance is necessary for nailing the finishing);
• gets nailed furniture staples or small nails a sheet of foam rubber required thickness(usually no more than 1 cm);
• decorative faux leather trim is nailed down with decorative furniture nails, forming a roller around the perimeter of the door;
• the lock, peephole, door handle are installed in place;
• if necessary, and depending on how the door opens, you can nail sealing beads made of leatherette with foam rubber onto the door frame around the perimeter.

If the door is metal, then everything will depend on its design. As a rule, metal doors already require a sound-proofing filler (it also performs the function of thermal insulation). But some inexpensive metal doors are hollow, so they not only do not block sound, but even enhance it, thanks to the drum principle. Fortunately, such doors can often be disassembled into two halves and filled with inner space sound insulation.

For sound insulation, materials that are lightweight and well fill the distance between the stiffeners are used. Best to use mineral wool and materials based on it. It fits easily and tightly, has excellent sound-proofing and heat-insulating properties, and, very importantly, does not burn.

It is not recommended to use foam plastic and polystyrene foam boards as a material for soundproofing doors from the inside - they will only provide insulation for the door, but will not improve sound absorption. Moreover, if installed incorrectly, these slabs will enhance the drum effect.

Do-it-yourself soundproofing of an interior door

Soundproofing of interior doors can be done according to the same principle as soundproofing of a wooden entrance door - using a thin sheet of self-adhesive soundproofing material and decorative finishing with foam rubber (which also reduces audibility).

If it is important to prevent sounds from leaving the room, for example, for home music studio, then in addition to soundproofing the perimeter, you can stick acoustic foam rubber on the entire surface of the door. You need to stick it on the side of the sound source. The height of the foam relief should not interfere with opening and closing the door.

Soundproofing materials based on bitumen are quite heavy, like leatherette, so before performing soundproofing work on interior doors it is better to strengthen the hinges.

However, the most beautiful solution, harmoniously fitting into the interior and not requiring additional measures, will be a factory soundproof interior door.

Soundproof doors

During a major or first renovation, it is better not to skimp on doors (both entrance and interior) and choose them not only for appearance, but also in terms of soundproofing and thermal insulation indicators. This will help you save on further strength, money and nerves.

Entrance doors with sound insulation must be made of metal with a sheet thickness of at least 2 mm. The sheets must be tightly fastened and not vibrate.

It is important that both the door itself and installation box were filled with soundproofing material (mineral wool, isolon, etc.). It is ideal if the manufacturer uses several sound insulators. One of them is glued to steel sheets for vibration protection, the other is used as a filler.

At least two sealing contours should be created around the perimeter of a good soundproofing entrance door.

Interior doors with sound insulation must also be equipped with a seal. If the door consists of two layers of veneer and filler between them, then the filler must be soundproofing.

Solid wood doors are good at blocking sound, especially if hardwood is used. The thicker such a door, the better performance soundproofing.

If good sound insulation is important, then it is better not to opt for doors with glass inserts. Glass doesn't block sound well enough.

Materials used for sound insulation can cause additional benefits: There are fireproof, soundproofing doors and doors with enhanced thermal insulation.

Of course, take everything into account possible requirements to the doors, it is better at the stage of choosing them in the store. But, if you made a mistake with your choice, then proper soundproofing of doors can easily be done with your own hands. you just need to carefully study the installation technology, find a suitable soundproofing material and get to work!

Reduce the level of noise entering the room from the street and from next room, you can use sound insulation. Increasingly, in apartments and private houses, not only entrance but also interior doors with sound insulation. Sound insulation will help get rid of extraneous noise, which will have a positive effect on the level of comfort of the residents of the house. It is not necessary to replace every door in the apartment with a soundproof one; existing structures can simply be modernized.

A sound-absorbing interior door can have different designs, such designs may differ from each other in the opening method and material of manufacture, the same applies to dimensions. Features - the presence of seals both inside and around the perimeter of the entire product, which ensures a good fit to the box.

Despite the external similarity with conventional designs, internal filling sound-absorbing structures have their own characteristics. Soundproofing doors can be done using:

1. corrugated cardboard is the most budget material, losing its properties in the first years of use;
2. mineral wool - creates a non-flammable plane, but during operation due to the resulting voids it cannot fully retain noise;
3. foam board - along with high sound insulation properties, it also has its disadvantages, for example, it is a highly flammable material that is dangerous due to the release of toxic gases;
4. foamed polyurethane - retains noise and extraneous sounds, while meeting all requirements fire safety.

The sound absorption level of soundproofing doors is 27-40 dB, which is determined by the quality and quantity of the filler. Yes, thin and lightweight design is not able to get rid of external noise, so it is worth installing a door with more reliable protection.

Additional soundproofing methods

As effective ways Soundproofing improvements can be applied:

• glass insert;
• sticking to door frame sealing tape;
• installation of two-layer glass doors With air gap;
• the use of special brushes that retain noise.

Interior door designs with a high degree of sound insulation are presented in a large assortment and can perform a number of additional functions. For example, thresholds in doorways will help not only reduce the level of external noise, but also maintain heat inside the room. But they can interfere with smooth movement around the apartment. In this case alternative option will be " hidden systems" You can reduce the noise level by using:

1. Rubber sill, which will allow you to close the gap under the canvas, while the opening and closing process will become much easier.
2. The “smart threshold” system completely isolates the gap under quality doors when they are closed, but if opened, a mechanism is activated, causing the seal layer to rise by the desired height. Thanks to this design, drafts will be eliminated in the room.

If desired, you can do good sound insulation and on old doors, following the diagram below:

• The door frame must be in tight contact with the wall; sealant will be needed to seal the holes.
• We treat the soundproofing sheet on both sides with a special mixture.
• As a decorative finish for a soundproof door, leatherette is used, nailed onto small nails.
• To close the gap between the canvas and the box, a seal is glued.
• Installation of a flexible or “smart” threshold.

Design features for interior doors

Soundproofing door structures are based on plastic, metal, glass and fiberboard. Wood and similar materials suitable for swing doors, and plastic and metal - for sliding products. With the latest models it is impossible to fully protect the room from penetrating sounds.

Apartment doors of similar quality are offered with a frame covered in MDF and chipboard. This technology manufacturing is more typical for old-style designs, but now models are equipped with a cardboard insert filled in the form of honeycombs, which, due to their elasticity, retain extraneous noise.

Doors made from natural wood.

Decorative glass and mirror inserts reduce the level of sound insulation, so optimal glazing is considered to be up to 20% of the total area of ​​the canvas. To improve protection performance, it is better to install a double or triple design. Hardwoods can reduce noise penetration by about 20 dB. Even if the design does not contain sound-absorbing materials, wooden doors will be considered soundproof.

Achieving complete sound insulation is possible in the case of a minimum gap from the box to the canvas. An example would be structures that have a double ledge with a protruding groove and layer polymer seal.

Advantages and disadvantages

Sound retention is not the only purpose of soundproofing products; they are endowed with a number of related functions:

1. Prevents corrosion of structures. Thanks to the insulating filling, interior doors are protected from the growth of mold and other pathogens.
2. Strengthening the structure.
3. Thermal insulation of the room. Almost all soundproofing fillers retain heat, closing cold bridges and preventing the formation of drafts.

Installing such a door will allow you to solve several problems at the same time.

How to choose

When selecting doors, it is important to pay attention to the following characteristics:

• material;
• door leaf structure;
• facing elements;
• thickness of the structure.

The most the best material wood is used to make silent interior doors. So, solid wood interior door leaf is capable of muffling external sounds by 10-15 dB. When using shields with an internal cavity, the opposite effect is possible - sound resonance will begin, which will lead to an increase in noise penetration into the room.

To solve this problem, it is advisable to use special filler materials. In a similar way, the sound insulation of plastic or metal structures, the purpose of which does not involve ensuring silence.

As an additional protective agent You can apply metal foil with a soft lining. This sandwich reflects sound waves well and prevents them from penetrating inside.

If installation metal doors is prerequisite, then sound insulation is carried out not only by the internal filler, but also by the external cladding for aesthetically pleasing products. Wood trim of any type looks attractive - solid wood, MDF, lining. Often craftsmen make upholstery made of artificial leather, which will look good against the background of the interior and will reduce the noise level.

Features of selection by opening method

The level of noise protection depends on the type of door structure. Plastic door considered the worst soundproofing structure. Roller shutter doors with aluminum (wooden, plastic) slats do not cope with this task. Also, you should not rely on sliding ones; the accordion is not able to absorb sound.

How to make it yourself

Do high-quality sound insulation you can install an interior door yourself; to do this, it is sheathed with acoustic materials filled with filler so that there are no cracks or gaps. All the work is done simply, you just need to follow the suggested instructions:

1. Upholstery material. You can use genuine leather, leatherette, vinyl and other similar products. Special boards with an adhesive layer are well suited, which makes them easy to stick to the canvas.
2. Filling: batting, padding polyester, foam rubber. For fire safety purposes, experts recommend using mineral wool, which absorbs extraneous noise and does not support combustion.
3. All cracks in the frame and walls are filled with sealant.
4. Upholstery with a soft noise-absorbing pad is nailed to one or both parts of the canvas.
5. Gluing the seal. The material should not get into the gap; it serves to close it. From the canvas to the sealing tape should be maintained minimum distance- no more than 10 mm.
6. Installation of a threshold or seal to the bottom of the doors.

Thus, soundproofing interior doors with your own hands will help get rid of extraneous sounds in the room. However, the doors will not be able to provide complete silence; for this it will be necessary to additionally work with the walls, ceiling, floor and windows.

For good productivity and good health, a person must get enough sleep and at least sometimes rest in silence. And if a large noisy family lives in the house, there are small children, or a novice musician is honing his skills, then sometimes it becomes simply impossible to concentrate and collect his thoughts.

Places where without increased sound insulation You just can't get by with this:

• Bedroom and children's room;
• Study;
• Recording studio;
• Creative workshop;
• Hotel or hotel number.

To solve the problem of excess noise, you need to take care of soundproofing the rooms, and first, choose the right interior doors. If they have a sufficient degree of sound insulation, this will help get closer to the desired level of silence.

One of the options for solving the issue could be soundproofing interior doors with your own hands, but it is much easier to initially buy quality product, which does not require any modifications.

It is quite logical that the sound insulation of interior doors depends on the quality and thickness of the door leaf. Therefore, a product made from solid or laminated solid wood, ideally from hardwood, will best cope with the task of sound insulation. Since the material itself is expensive and not available to everyone, widespread received other types of interior doors made of fiberboard, glass, metal or plastic.

Types of doors and their characteristics

Knowing what kind of sound insulation each material has, choosing interior doors becomes much easier.

Regardless of the material from which the door is made, it is important to consider sealing the door frame around the entire perimeter. Any gaps will facilitate the penetration of sounds into the room, and vice versa.

Sliding structures

Considered very comfortable in terms of ergonomics sliding doors. They are made from metal or plastic. However, the sound insulation of sliding structures is a priori considered minimal, since a small gap remains between the doors even in the closed position, and metal, moreover, is itself a good conductor for any sounds.

Picking up sliding structure for the home, you need to pay attention to the type of opening. There are 2 options: in the first, the doors slide along the wall when opened, and in the second, they hide in a niche inside it. In the latter case, sound insulation is better, since there are no unnecessary gaps between the wall and the doors.

To reduce the level of sound penetration when installing sliding interior doors, it is necessary to fill all possible gaps in the opening. First of all, there is a gap between the sash and the wall; a plinth is used for this. To close the gap between the ceiling and the door leaf, a carriage is used.

You can also install a sliding structure, for the manufacture of which sandwich panels were used. She has high level sound insulation, and can hold up to 50 dB. However, such structures are very heavy and cost a considerable amount of money, so they are more suitable for installation in offices rather than in homes.

Additional measures for sound insulation

To achieve maximum effect, you can specially purchase ready-made interior doors with sound insulation, manufactured using the sandwich principle. However, such a product may not always fit into the interior of the house. Therefore, it is worth taking care of strengthening the existing structure. It is known that thanks to only one correct installation You can achieve a noise level reduction of 12 dB.

Let's consider effective means for increased sound insulation of doors:

1. First of all, it is necessary to use a sealant to seal the cracks, and sheathe the canvas itself with a special coating on the noise penetration side. To insulate the door with your own hands, you can use sound-absorbing boards by gluing them to the surface using mastic.
2. Installation of double hinged doors. In this design, the folds fit tightly to the box, and a rubberized seal is laid along the entire perimeter of the rebate.
3. Installation of additional door leaf. In this case, an air space is formed that can eliminate excess noise. Such soundproof doors are rather rare for residential buildings, because in terms of convenience and aesthetics they are not entirely attractive. But this is a completely reasonable solution if one room is intended for work that requires silence and concentration, or, conversely, the noise produced in the process will disturb the household.
4. To achieve maximum sound insulation effect, in addition to strengthening the door and opening, you should take care of additional cladding of walls and ceilings.

Knowing how to soundproof a door with your own hands, you can solve several problems at once: save cash without paying for labor employees, and also achieve the desired peace and quiet.

Any decorative inserts made of glass, plastic or mirrors reduce the soundproofing properties of interior doors. When choosing a product with a glass insert, you must give preference to double or triple glazing. A blank canvas has the greatest sound resistance.

Threshold sealing as another way to achieve silence

The issue of soundproofing an interior door should be approached comprehensively. After all, even the best-quality canvas cannot protect against excess noise if there is a large gap under it.

It is for this reason that previously all houses had high thresholds - they are able to absorb unnecessary sounds. However, this is inconvenient when there are small children or elderly people in the house. Therefore, some manufacturers offer a “smart threshold” system. It is mounted in the lower part of the door leaf, and when the doors are closed, the threshold falls out of the groove, tightly closing the gap. Such a system is able to absorb most of the noise coming from other rooms. When opened, a mechanism is activated, thanks to which the threshold is hidden again in the canvas.

Interior doors with good sound insulation are The best way without extra costs provide the desired silence in the house after a difficult working day. Moreover, there are many ways to enhance soundproofing properties, starting with the purchase of a special door and ending with the installation of appropriate fittings. The main thing to remember when trying to achieve complete sound insulation is that you need to approach the issue comprehensively, and, if possible, make additional cladding for the ceiling and walls.
