Before the arrival of frosts, it is worth finding out how to seal the windows to be sure that the uncomfortable temperature prevailing outside does not be able to know the household members.

● Both plastic and wooden windows can be sealed with seals , sponges, foams and sealing tapes. ● Sealing windows with sealing tapes is better to commission to professionals, because this operation requires dismantling of the window. ● Before you decide to replace the seals, check the source of leaks and adjust the windows in accordance with the user manual.

Sealing of plastic windows with gaskets

It is estimated that as much as 30 percent can escape through leaky windows. warm, so before the arrival of winter, it is worth finding out how to seal windows, not only to keep the desired temperature in the rooms, but also save on heating the house or apartment.

plastic windows are made in PVC or PVC technology, thanks why they provide excellent thermal comfort. Unfortunately, these types of windows are also exposed to leaks. Used seals are the most common cause of plastic windows leaks. The replacement of this window element is not particularly complicated and even hardly experienced DIYs can cope with it. The best materials available on the market for window sealing are EPDM gaskets, which are distinguished by durability providing protection for windows for several years. You can also opt for a polyurethane foam gasket, which only slightly gives way to the quality of the EPDM seal.

both types of seals are self -adhesive and are not very expensive, they are easy to assemble and perfectly fulfill their own functions. However, you must remember to choose the right size (thickness) of seals, because the poorly selected seal will not fulfill its task. Information about the dedicated size of the gasket to a given window is found in the warranty card or contract transferred by the company that installed the window.

To seal the plastic window, remove the old gasket, thoroughly clean the entire surface from the remains of glue and degreased it alcohol -based agents. The next step is to wait a few minutes to completely evaporate the degreasing preparation, at this time you can measure and cut a new gasket to the required length. The seal is mounted by removing the paper protecting the adhesive part and sticking to the frame.

How to seal plastic windows with sealing tape? People who do not have experience in this topic. This type of sealing requires a window disassembly, so it's best to employ professionals for this purpose. On the outside of the window, vapor permeable or polyurethane tapes are used, whose task is to provide the wall of adequate air circulation. From the inside, vapor -tight tapes are put on, which form a barrier for moisture and prevent it from penetrating the wall. Possible defects and gaps between the tapes are filled with polyurethane foam.

How to seal plastic windows with sealing foam?

sealing foam is usually used to seal windows at the contact of the frame with a wall. Its application is not particularly complicated, but you should pay attention to the manufacturer's recommendations regarding the temperature or humidity in which the foam can be used. Another issue to keep in mind is that polyurethane foam after applying two or three times increases its volume, so you can't overdo it with its quantity. People who do not have experience in using such foams can decide to buy this type of product with a reduced volume, i.e. low -pressure foam. Thanks to its flexibility and increasing volume, the sealing foam perfectly fills all defects between the wall and the window, and it is resistant to mold and mechanical damage.

After applying polyurethane foam in all defects, wait a while for it, wait for it to dry, and then remove excess product by cutting it with a knife. The resulting seal should be protected against the lowering of the insulation foam with UV radiation - this can be done with the help of plaster, paint or tapes.

how to seal plastic windows - a sponge

The sealing sponge has a similar specificity of assembly as Self -adhesive seals, which is why people who have no practice in the replacement of window seals will be able to handle it. In the case of sealing sponges, it is very important to choose the right thickness of the product. Here, as in the assembly of gaskets, data with the recommended thickness of the sealing material can be found in the warranty card or contract with the assembly company. Another similarity to other methods of sealing windows is to properly prepare the place where a self -adhesive sponge is to be found, i.e. removing used sealing and washing and degreasing the surface. Installation of this sealing material is carried out by cutting the length fitted to the size of the window, peeling the protective tape and sticking the sponge to the frame. The technique of gluing the sponge gaskets is very important - do not immediately peel off the entire safety tape, but only about a five -centimeter piece that can be glued to the frame, and then successively peel off after another fragment of the tape by gluing and thoroughly pressing the sponge.

Important information for those who decide on this method of sealing the window is that it is recommended to install a sponge at a temperature higher than 5 degrees Celsius. It is also worth knowing that currently produced windows sealing sponges significantly outweigh their quality those that are known from the 80s or 90s. Modern sponges do not turn yellow, do not crumble and if they are properly glued, they should not get off.

How to seal wooden windows?

Wooden windows can be sealed in exactly the same ways as PVC or PVC windows. The matter of sealing balcony doors and roof windows is similar - in these cases all the above -mentioned methods will also be great. And although each of these methods is effective, it is worth starting by checking whether sealing the windows of any of them is necessary. To do this, the leak should be locked and assess whether the gasket is actually replaced. If it turns out that cold air gets inside through the gap between the glass and the window frame, just use silicone to seal only this part of the window. The colorless silicone will work best, which will not be visible after hardening. Neutral and acrylic silicones are available on the market, of which the latter are characterized by increased resistance to temperature changes and UV radiation.

Before starting work related to windows sealing, it is worth finding out how to adjust the windows for the winter . Each type of window can be regulated differently, but in most cases it is not necessary to call professionals, as these activities can be carried out yourself. Information on window tightness regulation should be included in the user manual attached to the warranty card.
