Replacing the seal in plastic PVC windows necessary if you begin to feel a draft in the room.

Window gum – special material, which ensures the tightness of the connection of the sashes to the frames. With active use, the seal is subject to mechanical damage and rapid wear.

Also, the window seal, regardless of whether it is rubber, silicone or rubber, loses over time

elasticity, as a rule, needs to be replaced after 7 - 10 years of use of windows.

Replacing the seal in plastic windows- the only way to eliminate heat leaks at the junction of the sash and the frame.

Our company’s employees first carry out an external inspection and select the required brand of rubber seal.

When performing an operation on PVC profiles Only original components from the respective manufacturer are used. During installation, no devices are used to speed up the work, the use of which can damage the rubber. The process is carried out for both external and internal contour at the same time, this is the only way to guarantee quality.

From the outside, this operation does not look too complicated; some people try to do it themselves. However, there are a lot of subtleties here and therefore such attempts often lead to even greater drafts through unprofessional installed elements. Replacement is usually done on their own in order to save money; consumers buy cheap components, which only aggravates the problem.

Materials are sold wholesale in large quantities up to 500 m. They are intended for enterprises that produce windows and doors, or companies involved in their installation, maintenance, and repair. In retail, their price is quite high and there are no benefits from self-replacement the client cannot receive it.

All PVC double glazed windows: Veka, KBE, Rehau, as well as other manufacturers, have their own systems with their own tolerances. The use of non-original seals only leads to deterioration general characteristics designs. This is easy to understand from the following example:
It would seem that if you install a thicker rubber band, this will eliminate the flow of cold air from outside.
But this greatly increases the load on locking elements, which often leads to adjustment violations and even system breakdowns.

Our craftsmen work in Moscow , Moscow Region, Kotelniki, Zhulebino, Novokosino, Reutov, Dolgoprudny, Korolev, Krasnogorsk, Odintsovo, Mytishchi, Lyubertsy, Pavshino, Aprelevka, Moskovsky City, Balashikha, Zelenograd, Khimki, Vidnoye, Vnukovo, Kommunarka, Shcherbinka, Butovo, at prices below market prices.

A window seal is a product made of silicone, rubber or rubber, which is used to ensure that the window sashes fit tightly to the frame and the tightness of the structure as a whole. During active use of windows, the seals wear out, so replacing the seals on plastic windows is a popular service in Moscow.

The MasterMax company offers its seal replacement services to its customers. The company's masters are used in their work professional equipment and premium materials, which allows you to perform work quickly and efficiently.

Replacing window seals

Replacing the seal on windows is carried out in cases where:

• the old seal is cracked, swelling has appeared at its corners, the seal looks dried out and compressed;
• when the doors are closed you feel a draft;
• V winter time Frost or condensation appears on the windows.

A high-quality seal is protection from cold, noise, and moisture. That is why its condition must be monitored and, if its structure is damaged, measures must be taken to replace it.

Replacing rubber window seals

Replacing the rubber seal in windows is carried out in the following sequence:

• window inspection;
• selection of a new seal that matches the parameters;
• removing the old seal;
• fixing the new seal;
• checking the tightness and quality of closing the window.

Sealing rubber for PVC windows is one of essential elements design, responsible for the tightness of pressing the sash to the frame. You can buy the most expensive window and install it using the most modern mounting tapes, but if the rubber contour is not in order, then drafts and heat loss will become constant companions of your home.

Many years of experience with metal-plastic windows allowed me to understand the characteristics of the materials most often used for the manufacture of sealing contours. In addition, in one of the sections of this article I will tell you how to properly care for the elastic bands, and how to replace them with your own hands if the contour loses its tightness.

Why is it needed?

Sealing elements made of elastic materials are necessarily included in the package of PVC structures. As a rule, they are installed where the protrusion of a profile adjoins a flat surface - either another profile or glass (or a material that fills, for example, a sandwich panel).

The main functions of the sealing circuit are:

1. Elastic material located around the perimeter of the window opening ensures maximum tightness of pressing the sash or glass unit to the frame.
2. Due to the tight clamping, we receive protection from precipitation and street noise entering the room.
3. The absence of gaps, ensured by the presence of a sealing gum, contributes to more efficient heat conservation: heated air does not leave the room, so heat loss occurs only due to convection or radiation.
4. Finally, the presence of a sealed circuit protects the fittings from external influences: the mechanisms that move the sash and ensure the locking of the structure are isolated from moisture and dust, and therefore last much longer.

As you can see, the list of functions is quite extensive. At the same time, sufficient responsibility for their implementation simple detail, which is installed in a special groove on the profile directly during its production.

However, despite all their simplicity, seals can also be different.

Main varieties

Type 1. Rubber

The most common are rubber elements. They began to be used in the very first plastic windows, but even now many manufacturers prefer them:

1. The material is based on rubber, which is vulcanized using sulfur under the influence of harsh ultraviolet radiation.
2. Also, carbon black is added to the material, which ensures that the product retains its elasticity.

Black rubber inserts are stronger and more durable than painted ones. Primarily due to the high content of gas soot.

1. The advantages of rubber products include maintaining elasticity under temperature changes (even in very coldy), mechanical strength and low tendency to deformation.
2. Rubber has essentially one drawback - not everyone likes the black contours, especially around the glass unit.

Type 2. Silicone

Silicone is another material that is used to seal PVC windows. Its advantages are obvious:

1. Maintains flexibility in the temperature range from -40 to +1500C.
2. Complete absence of volatile toxic substances.
3. Minimal deformation even under prolonged load conditions.

At the same time, circuits made from silicone cord also have disadvantages:

1. The price of the material is quite high (higher than rubber).
2. Silicone breaks relatively easily, so the reason for replacing the circuit is usually not wear and tear over time, but mechanical damage.

Type 3. Plastic polymers

The largest group of materials used for the purposes described in this article are synthetic polymers. I will characterize the three most commonly used compounds in the table below:

Material	Peculiarities
PVC	Polyvinyl chloride is the cheapest composition, and is widely used in the production of windows that are installed in heated residential premises. It differs from PVC used in the manufacture of profiles in greater elasticity (less hardener, more additional components). An unpleasant feature of PVC contours is their tendency to harden in the cold: when overcooled, the elasticity of the material decreases, due to which the pressing density of the sash to the frame decreases. The service life does not exceed 5 years, but I would recommend changing the seals at least once every three years.
TPE	Thermoplastic elastomer is a synthetic polymer with good performance properties. In the cold it does not “stubble”, but behaves like high-quality rubber, and in the heat it adheres tightly to the surface. It is used relatively infrequently, due to the complexity of production of the material. But at the same time, the share of TPE products on the market is gradually growing.
EPDM	Ethylene-propylene diene monomers are also produced synthetically. As a result of processing organic raw materials (usually waste from polymer production), the material acquires good elasticity and high mechanical strength. Due to high level vulcanization, the contour does not crack even after prolonged exposure to load. Service life – 15-20 years.

Type 4. Polyethylene with filler

Polyethylene (or rather, polyethylene foam) seals are also sometimes used for plastic windows. The filler for such products is foam rubber and other porous materials.

However, the performance indicators of such products are relatively low:

1. The elasticity of the material does not last long, and after a long stay in a compressed state (with the sash closed), the contour rather slowly restores its shape.
2. With prolonged hypothermia, the material becomes rigid and can crack, either spontaneously or under load.
3. Finally, the strength of polyethylene foam products is also low: they tear easily, and are almost beyond repair - they have to be completely replaced.

Taking these features into account, polyethylene with various fillers is used only as an additional seal.

Installation and maintenance

How to care for the seal?

In order for the window to maintain its tightness, and we do not encounter problems such as missing pressure or the appearance of drafts, both rubber and polymer inserts need to be looked after. Maintenance consists of periodically cleaning the product and applying various lubricants to their surface to help maintain performance characteristics.

Let's try to figure out what you can use to lubricate the rubber bands on plastic windows, and what you shouldn't?

1. Best to buy special remedy for rubber, PVC or EPDM. Most often it is included in a window care kit, but can be purchased separately.

1. Any neutral silicone-based lubricant will also work. Moreover, the quality will not be inferior to the special equipment, and the price will be cheaper.
2. WD-40 is also suitable, but is expensive. It makes no sense to buy it specifically for windows, but if the spray can is in the workshop, then why not use it?
3. Glycerin/Vaseline is a budget solution. The main disadvantage is that they dry out quickly and are not very well tolerated. low temperatures. To maintain the effect, it is worth repeating the treatment more often.

The list of what to lubricate the sealing circuit will be more extensive. I would say that you should not use automotive, weapons or vegetable oils, products with abrasives, as well as compositions containing alcohols and acids.

Care instructions are quite simple:

1. Open the door, then wipe all the rubber bands with a cloth or sponge soaked in soapy water.
2. After removing all dirt and old grease residue, wipe the seal dry.

1. Apply the lubricant first between the petals of the circuit (if it has complex design), and then spray it over the entire surface.
2. Using a brush or swab, distribute the lubricant along the contour.
3. We wipe away any remaining oil that has got on the front part of the profile or the glass unit.

Treatment should be carried out at least twice a year: in March-April before summer season, and in October-November before the start of winter.

Replacing the sealing circuit

Sometimes care and prevention do not help, and we have to figure out how to change the seal by installing a new elastic element.

To carry out the replacement ourselves, we will need:

• new material (the length of the segment must be appropriate);
• scissors;
• glue for polymers;
• roller for rolling.

We carry out the work according to the following algorithm:

1. First, remove the worn rubber band by carefully prying it up and removing it from the groove.
2. We clean the grooves from dust and dirt. To do this, you can use a special brush, which is included in the window care kit, but I limit myself to an old toothbrush. After cleaning, wipe the groove with a rag.

1. Apply a little glue to the corners of the frame.
2. We take a piece of sealing cord, place one edge in a corner and press it with glue for initial fixation.
3. Then we insert the cord into the groove and press it until the part intended for fastening is completely recessed into the recess.
4. We insert the cord along the entire length of the groove, rolling it with a special roller if necessary. The material should lie flat, without gaps.

You should try to make the contour closed, without cutting the cord. To do this, before replacing, I carefully examine the groove at the corners - usually the plastic deposits formed during welding are removed during the manufacture of the window, but a couple of times I had to trim the PVC myself.

1. We cut off the excess and glue the second end of the cord end-to-end with the first.

The task may seem difficult at first, but in practice, even beginners understand how to install a new rubber band correctly in just a few minutes.

Conclusion

Figuring out how to lubricate rubber bands on plastic windows and how to replace them is not difficult at all. At the same time, it is necessary to know this, because modern window requires maintenance, and the microclimate in the room largely depends on the condition of the sealing circuit.

The service life of some refrigerator parts does not always correspond to the declared one. Elements such as the seal often wear out. Replacing it will not require much time and money if you carry out the repairs yourself. We will tell you how to change the rubber seal on a refrigerator in this article.

Why do you need sealing rubber for refrigerators? The seal is a rubber band that holds the refrigerator door tightly against the refrigeration chamber so that air does not penetrate inside. If air gets inside, the refrigerator begins to wear out. Damage to the seal can be determined by the fact that ice begins to freeze inside the refrigerator, which usually accumulates on back wall, and also, if . The gap may be visible even to the naked eye.

Wearing out the old seal: what to do?

The gap in the refrigerator is determined using a regular sheet of paper. To do this, you need to insert it into the slot and move it. If the sheet moves freely, then the rubber band needs to be replaced, otherwise everything works correctly.

In some cases, you can quickly restore the refrigerator seal with your own hands. Of course, if the seal is torn or rotten, you will have to replace it. If the sealing rubber is slightly deformed, in order to restore it with your own hands, you can use this method: heat the deformed area with a hairdryer, change the shape with your fingers and firmly press the door, holding it there for a while. Minor damage can be corrected during such manipulations. If there is significant deformation, the rubber band must be lowered into hot water, and then insert it into place.

But sometimes it’s enough to simply adjust the refrigerator door if it doesn’t fit tightly. In this form, you don’t need to change anything, just adjust it. When there are cracks in the structure, it is worth checking how they were formed.

How to choose a replacement rubber seal

The rubber seal for the refrigerator can be various types and can be fixed different ways. Products come in one- and two-cylinder versions. They can simply be installed in a recess, or attached with glue to the surface, or installed using self-tapping screws.

You also need to pay attention to the part that will be glued; it must fit tightly. Some refrigerator models have special recesses for inserting an elastic band into the groove. This greatly simplifies the whole process, then there will be no need to glue it, you just need to insert it into the groove, and the removable structure is easier to wash.

If you screw the structure onto self-tapping screws, this method can damage the door or the seal itself. You can glue it, but it will be difficult to tear it off later. Therefore, it is better to choose a suitable rubber band for the refrigerator model.

Replacing the seal for the refrigerator

If the repair does not bring the desired result, then you will need to buy a new rubber seal for the refrigerator. The replacement process occurs in several ways. This mainly depends on how the seal was originally installed. Let's consider several ways to replace sealing rubber:

1. First you need to remove the refrigerator door and place it on a surface. Cut the old seal where it joins the door and tear it off. We cut the new sealing rubber so that its edges do not extend beyond the door. The new seal can be placed on double-sided tape.
2. To remove the old seal, you need to take a spatula and, lifting the seal, carefully remove it from the groove. Thus remove all old material. The new sealing rubber is installed in the grooves; you can use a screwdriver for this. Also, in order for the seal to hold more reliably, it can be glued with superglue.
3. If the sealing rubber was placed on the mounting foam, then to dismantle it, you can use a chisel or knife. First, remove the refrigerator door and adjust it to flat surface. Cut the seal and tear it off. Thoroughly clean from polyurethane foam door. In order to secure the new sealing rubber, holes for self-tapping screws are drilled around the perimeter of the door. Cut off the rubber required size and place it on the screws. We fasten the seal loosely, without tension. We install the door in place and use the awnings to adjust it so that it fits tightly and evenly to the refrigerator.

So, repairing or replacing some elements of the unit can save it. There is no need to immediately throw away the refrigerator; you can repair only one part in it, and it will work as before.

They have firmly entered our lives, because thanks to them, much more heat is retained in houses than when installing wooden analogues. But what to do if, for some reason, you begin to feel that they are not doing their job very well: there is a draft or the room is noticeably colder. In this case, it is not necessary to think about buying a new opening. Indeed, in most cases, simply replacing the seals on plastic windows will help solve the problem. You will learn from this material how this is done and what materials are required for such work.

When is it necessary to replace seals on plastic windows?

The quality of sealing the opening depends on the condition rubber gaskets ensuring a tight fit between the valves and each other. And there are several signs that it's time to carry out minor repairs plastic windows. Replacing the seal is necessary in the following cases:

• In winter time inside frost appears on the window block and on the windowsill.
• A draft began to flow through the apartment.
• The quality of sound insulation has decreased.
• Condensation occurs on the glass.
• Fungus or mold has appeared on the window sashes.

Any of these signs indicates that it is necessary urgent replacement seals on plastic windows.

Choosing material

There are many types of gaskets for plastic windows. And each type has its own characteristics and cost. To ensure that replacing seals on plastic windows brings as much benefit as possible without putting a dent in your wallet, you need to learn about all types of such material:

• Rubber compressor. This material is made from rubber with the addition of sulfur. This gasket is quite cheap, but can last up to 30 years.
• Silicone seal. Most environmentally friendly pure material, which can last about 40 years. Such a seal can be used both in residential and industrial premises. At the same time, it does not deteriorate from sudden changes in temperature, as well as from the action of UV rays, oxygen or ozone.
• Polymer seal (EPDM). The most expensive, but at the same time reliable option. It can withstand extremely low temperatures without cracking and retaining its shape. Service life - 20 years.
• Thermoplastic elastomer (TPE). An improved silicone seal with increased resistance to temperatures and mechanical stress. Today this is the most popular material, despite its fairly decent cost.
• PVC. Most cheap material with modest technical characteristics. Guarantee period service - 3 years. It is recommended to install PVC gasket only in warm rooms.

Replacing the seal in plastic windows with your own hands. Preparing for work

After you stock up necessary materials, you will need to prepare your windows for replacement insulation. First of all, you need to remove the old gaskets. This will not be difficult to do, because the insulation can be easily removed from the grooves. Next, you need to get rid of dirt and dust on the surface of the doors using a soft rag or sponge soaked in soapy water. The next step is to degrease the window. For these purposes, you can use alcohol, solvent or white spirit.

Main stage

Replacing rubber seals in plastic windows is a rather labor-intensive process that requires a little skill. So if you have never done anything like this, then practice on small area frames After you have thoroughly cleaned and degreased the windows, the grooves in which you will lay the insulation must be well lubricated with glue. After this, you need to insert the entire gasket, making sure that the material is not stretched or compressed. This is where the previous training comes in handy. After you have laid all the insulation, all that remains is to trim off the excess material and additionally apply glue to the joints of the gaskets.

Call a specialist

Adjusting plastic windows, replacing the seal - all these actions will require great care and skill from you. So if you are not confident in your abilities, then it is better to invite a specialist who will carry out such work in the shortest possible time and for a small fee.

How to increase the service life of seals

Despite the fact that gaskets for plastic windows are made of durable materials, they still wear out over time. In order for this to happen as late as possible, it is necessary to periodically lubricate the seals. This can be done several times a year, and this approach will help extend the life of the gaskets. What can be used as a lubricant:

• Glycerol. Cheapest and practical material, which can be purchased at any pharmacy. The only drawback is that glycerin quickly dissolves in water, so it cannot provide special waterproofing.
• Petrolatum. This lubricant can only be used on rubber seals. The advantages of this lubricant include price and water resistance; the disadvantages are the small temperature range that it can withstand (from - 25 to + 28 °C).
• WD-40. The most popular mineral oil, which will perfectly protect the seal surface from moisture and mechanical damage. In addition, this product is sold in cans, so it is very convenient to use. The only drawback is the price of the product.
• Silicone Grease. Range operating temperature from - 50 to 230 °C. In addition, this lubricant perfectly protects the seal from wear. The only disadvantages include the high price.
• Professional set. Most the best option to protect window seals. This complex is specially designed to protect insulation materials and keep them in their original form for a long time. But such a set is also quite expensive.

Replacing seals on plastic windows, as well as caring for them, will allow you to maintain the microclimate in your apartment. The main thing is to do everything correctly and according to the instructions. And then warmth and comfort will reign in the house for a long time.
