When is seal replacement necessary?

A few years after installing new plastic windows, you can notice how they begin to let in small drafts, noise and dust. This is the first sign that the seal in plastic windows needs to be replaced, the price of which is low.

Over time, the material begins to shrink and crack. Such seals do not perform their function well because they become harder and lose their plasticity.

The windows do not close tightly, and there are constant drafts throughout the apartment or house. Manufacturers claim that the service life is 5-10 years, but depending on the conditions and environment of use, it may be reduced.

If the sealing gasket wears out 5-7 years after installing the windows, there is nothing to worry about, since it has really outlived its useful life. It’s another matter when the seal has to be changed after a year of operation. In this case, this only means that the windows are made of cheap and low-quality materials and this is only the beginning of problems and breakdowns.

Every year, manufacturers delight us with innovations in their products. Just a couple of years ago it was difficult to keep the room warm, since the window frames were wooden with cracks that had to be sealed with tape or insulated with cotton wool for the winter. I remember all this very well because children even did it at school. But it’s good that progress does not stand still and makes our lives easier. Nowadays, almost every homeowner installs plastic profiles that do not let heat out and cold and dust in. Old windows required painting every year, but plastic windows cannot do without proper care.

What is a new generation window and how to care for it

There are many constituent elements of a window design: slopes, drainage, window sill, fittings, glazing beads, sealing contours, double-glazed windows and PVC profiles. The principle of window assembly developed by engineers makes it possible to produce packages of any configuration.

Advantages of PVC systems:

• Strength and durability.
• Relatively light weight.
• Variable opening.
• Easy care.
• What does the profile consist of?
• The frame is a box fixed in the opening.
• The doors are designed for partial opening.
• Impost - thanks to it, the box is divided into parts vertically or horizontally.
• Sealed glass unit.

Today, manufacturers use noise-insulating, energy-saving glass with protection from sunlight. The quality of a window depends on the fittings. If hinges and other mechanisms do not work well, they will create inconvenience for the user.

Sealing element in plastic profiles

If the sealing element has become unusable due to poor-quality material from which it was made or uneven installation of the glass unit, do not worry too much - it can be replaced.

Where is he located? The sealing tape is a rubber product that is fixed in small tracks of the window frame and located along the entire length of the structure. The main task is to ensure a tight fit of the glass unit to the frame in order to prevent the penetration of cold air from the street and warm air from outside.

Types of seals

Plastic profiles use different types of sealing element. The choice depends on the desires and capabilities of the customer. But the most used products are rubber and caoutchouc. Both have powerful resistance to low temperatures and the strength of the material is not so prone to damage.

Polyethylene is filled with foam rubber and does not return well to its previous shape after compression, while polymer is characterized by the characteristics of the profile itself. This provides good tightness, but the properties that rubber and rubber have are not available to them. They are affected by temperature and sun.

In what cases is it necessary to replace the seal in plastic windows?

From everything written above, it is already clear what the role of sealing rubber is. Damage to this component leads to depressurization and the penetration of odors from the street, sounds, and heat loss into the room.

Determining unsuitability is not difficult:

• Condensation appears in the corners of the glass.
• A crust of ice forms on the windowsill during the cold season.
• Traces of fungus or mold are visible.
• Cracks.
• Increased noise from the street.

Checking the window closure tightness

A thermal imager can identify places where cold penetrates, but there are simpler ways:

• A leak will be determined by a lit match or candle. The penetration of air from outside leads to vibrations of the fire.
• You can feel the draft with your hand.
• A piece of paper placed in a locked sash determines how tightly the window is closed. If the density is secure, it will be difficult to pull the sheet back out.

Which element to choose for profile sealing?

If you purchased a ready-made profile from a little-known manufacturer, rest assured that it uses the poorest quality elastic thermoplastic seal. It is convenient for automatic profile assembly, quite cheap and safe (low burn). Therefore, to avoid such a nuisance, try to control its use in your window or, after purchasing, immediately replace it yourself. A cut sample will help determine the type of sealing element used in the finished product. You can compare it in the store.

Not only the color that matches the window frame should influence the choice, but first of all the quality of the material of the element itself.

The choice will not be difficult if the double-glazed window is from a well-known manufacturer that has already proven itself well in the market. But when choosing a profile from a lesser-known company, you need to focus on the specifics of some window elements.

Many companies copy window manufacturing technology from top-rated manufacturers, so most profile components are interchangeable. Nowadays, with the advent of online stores, searching for goods has become much easier. A selection of components is also presented on Internet sites; the main thing is to know the dimensions of the structure and add 15 - 20% to them for reserve. Do not forget about the thickness of the layer, which should be identical to the previous one. Try to purchase a high-quality seal, the money savings will be reflected in the functions of the double-glazed window. It wouldn’t hurt to study the requirements of GOST 30778-2001 before purchasing. This will help you make the right choice.

In order for the seal to last longer, preventive maintenance is required from time to time:

• Wipe down and clean your windows and seals at least twice a year.
• Apply softening agents - glycerin or silicone solution - to the rubber product to prevent cracks from appearing.
• Detergents containing fat are contraindicated. It penetrates the structure of the seal.
• If the room is undergoing renovations and there is a lot of dust, close the window to prevent it from settling on the sealing elements.

Replacing rubber seals in plastic windows is needed when methods to correct problems do not produce results.

First you need to try to adjust the tightness of the window closure. To do this, insert a key into a special hole and turn it until the desired result appears. If adjustment does not return the seal to normal, it is time to change the seal. When it is not yet very worn out, it can be renewed with aerosol lubricants.

Do-it-yourself replacement of plastic window seals

Tools and materials you will need:

• Glue gun.
• Silicone glue.
• Scissors.
• New seal.

How to prepare for replacement:

To make the procedure more convenient, remove the sash. When the window is locked, the protective covers are removed from the hinges. The pins are knocked out from the top canopy. Holding the sash when the window is open, it is disconnected from the frame. It is very important and necessary to know that replacement must be carried out along the entire length only with a solid sealing tape. You can't do this from pieces. It is also forbidden to stretch it. Loose laying without tension is recommended.

So, the following rules for carrying out this procedure will help you do everything efficiently:

1. The old seal must be removed from the channels using scissors. To do this you need to pry it and pull it.

2. Be sure to wipe the vacated channels. Make sure that lint does not get into the openings, it will interfere with the fixation of the new seal.

3. Adhesive should only be applied to the corners of the channels. Use “Cyanoplast” or “88” superglue.

4. After this, lay the new tape carefully and around the entire perimeter. Make sure it fits well.

5. Remove excess parts with scissors.

6. Glue the joints to the corner of the frame.

7. Wait for the glue to dry and insert the window frame into place.

The types of self-adhesive seals are changed as follows:

1. Place the window sash on a flat surface.

2. Remove the protective tape from the seal.

3. Install with a protrusion for fastening the groove, which runs along the perimeter.

4. Press the tape, but not too much.

5. Return the sash to its place.

As you can see, replacing the seal of plastic windows does not require the help of any specialists and almost anyone can handle it.

Does the seal need to be lubricated?

If you want the sealing tape to last longer, you need to lubricate it. Because rubber becomes dry over time and cracks appear. Special lubricants moisturize the material of the element and protect it from the effects of wind in the same way that cream protects the skin of the face. You should choose the product carefully so that it does not contain solvent acids. Such chemicals have a destructive effect on the structure of the material and reduce its service life.

Among lubricants, regular Vaseline and glycerin are popular. Sometimes WD-40 is recommended for lubrication. Yes, it is needed, but to get rid of rust, not for lubrication.

Previously, the properties of seals and their types were superficially described. Let's take a closer look at which type is the highest quality and most effective to use.

For modern window structures, three types of manufacturing materials are mainly used: silicone, rubber and polymer. Which of them has properties that allow it to be replaced less frequently.

High quality PVC is used for polymer, but still this criterion does not provide it with the required degree of protection from high and low temperatures. It can soften in hot weather and harden in cold weather. Ultraviolet rays also have a negative effect on it. You shouldn’t even think about using polyethylene. It has the lowest quality of all. The most expensive is silicone, it has the same disadvantages as polymer and is inferior to rubber.

The universal and most common seal is rubber or rubber. It is more resistant to wear and has all the properties to protect against wind, temperature changes, and sunlight.

Don't think that color has nothing to do with quality. This is not at all true, since to acquire a particular color, elements are added to the raw material that affect the characteristics of the product. For example, soot is added for black color. It gives the material elasticity. Gray or white color requires the addition of polymers whose properties are listed above. Consequently, colored sealing tapes are inferior in quality to black ones, and they also darken over time.

So, as a result of comparing the properties of each type of material for the manufacture of a seal product, the choice becomes clear. This is a rubber or rubber seal.

Adjusting the window according to seasonal indicators is important for extending operation. In warm weather, the eccentrics at the end of the window are turned inward with a marker; in cold weather, in the opposite direction. In this way you can regulate the degree of pressing of the valves.

Before you carry out any manipulations to care for any equipment and structures, you should find information on how this is done. Moreover, there is plenty of it on the Internet. You can even get advice online, because almost every manufacturer has its own website, which describes the product and its care in detail. Not every consultant in the store will tell you in detail how to replace the seal, but on the Internet you will find what interests you. To compare information, visit several sites and choose the best option for you for selecting a window profile and replacing components.

By listening to all the recommendations for caring for window structures and their components, you can ensure energy conservation in your apartment and relax comfortably after a hard day.

The service life of window seals made using modern technologies is estimated differently: from 3 to 10 years, depending on care, temperature changes and many other factors.

The materials from which window seals are made are quite durable, usually made of foam rubber, but it is still rubber, which means it is exposed to temperatures, especially significant and sudden temperature fluctuations, which is not uncommon with the changing climate in Moscow.

But it must be said that there are seals that are resistant to aggressive external environments and large temperature changes; these are German seals based on polyurethane foam. Therefore, to keep your apartment warm, sometimes you just need to replace the window seal.

Old rubber can no longer provide reliable protection against air and noise, so the only right solution is to replace it.

What sealant is used on PVC windows?

Seals are elastic gaskets of a tubular or more complex cross-section that run along the entire perimeter of the window, between the frame and the sashes, and protect against cold air, noise and moisture. Manufacturers make modern window seals from silicone, rubber and caoutchouc. But the most durable seal is considered to be EPDM - a synthetic rubber that can withstand large temperature changes. It is not subject to deformation and has high elasticity, which has a beneficial effect on its operation.

Moscow's harsh winters require warm windows. Compared to a large amount of foam, profile and double-glazed glass, the seal takes up a small area on the windows. If it is of poor quality, then it will leak through the window. Condensation or ice will appear. This is why it is so important that PVC windows have a high-quality seal.

Types of plastic window seals

Seals are a very important component of a PVC window, which periodically needs to be replaced. There are several materials from which such products are made, so when it is necessary to replace rubber seals on plastic windows, buyers can choose from options such as:

• EPDM (ethylene propylene diene rubber) seals have high elasticity and hold their shape well. They have a wide range of operating temperatures (-50°C to +55) and are resistant to UV radiation. Service life – 10-15 years. Black color.
• TPE (thermoplastic elastomer) - the most affordable products, provide a tight fit in the corners of the window. Operation is possible at temperatures from -65°C to +150°C. The ultimate tensile strength can reach 100 kN/m. Service life is from 5-10 years. Any colour.
• Silicone seal
  is the most reliable and durable product. The service life with proper care is at least 20 years. Operation is possible at temperatures from -60°C to +120°C. Silicone is resistant to aggressive environments, but has a tendency to deform. Any colour.

There are also other materials, but they are not very common now. Nevertheless, replacement of rubber bands in Moscow is carried out on different windows, and technology is moving forward and new materials with higher properties are constantly appearing than classic rubber based on artificial rubber.

What problems will replacing the seal save you from?

• Condensation and mold. If your windows often “cry,” you risk developing mold and mildew in the window opening. By replacing the sealing rubber, you will adjust the thermal balance of the glass in the double-glazed window and eliminate the root cause of the problem.
• Freezing. The formation of a crust of ice on a double-glazed window will also not lead to anything good. By ignoring this circumstance, you only provoke rapid damage to the window frame and fittings.
• Draft and noise. The window should protect from cold, wind and street sounds. If you don’t want to endure these unpleasant circumstances, take care of the quality of the sealing rubber.

How to care for a window to extend its service life?

To do this, just follow a few simple rules:

• Periodically wash the window and seal with detergent.
• Do not allow alcohol or other aggressive acids to come into contact with the window.
• Do not allow the window system to freeze.
• Treat the seal with special protective agents (the manager will select the appropriate one for you).

Regular window maintenance is also important. This is especially true when the season changes: every autumn and spring it is necessary to adjust the fittings.
