Windows
Plastic windows are distinguished by excellent technical parameters. They are resistant to weather conditions and chemicals. Thanks to their extraordinary durability, they will serve you for up to 40 years. Properly installed PVC windows are characterized by exceptional tightness, therefore in unventilated rooms it may be necessary to install diffusers that ensure adequate air circulation. By choosing plastic windows you will not have to worry about their maintenance. It will be enough to carry out simple care treatments.
In addition to technical parameters, PVC windows have an interesting appearance. Although we still associate plastic windows with the white color of frames, the manufacturers’ offer includes a wide range of colors, which we can adapt to our own needs.

When the house is new, it is worth reaching for a project in which the sizes of each window will be determined. It is also necessary to measure the openings, because sometimes their dimensions differ from those determined in the house design. Before buying windows, you should consider whether the included dimensions and shapes of windows meet your expectations. People who plan to replace the window joinery will not have problems with determining the dimensions of a plastic window. Then it is enough to choose a product with dimensions corresponding to the PVC windows in a given room.
An important factor to keep in mind is the number of chambers of the window profiles. The more chambers, the better the window insulation parameters. Three-chamber window profiles have become a rarity. Profiles with five or eight chambers are becoming an increasingly common solution. The profile class is equally important. The highest class marked with the symbol A has the greatest thickness of the outer walls and the width of the inner chambers. Choosing plastic windows with A-class profiles, you can be sure of their high durability, stability and protection against weather conditions.
When choosing window joinery, it is worth paying special attention to seals that are used to ensure water tightness, heat loss and noise protection. In plastic windows, gaskets made of rubber (EPDM) or a mixture of EPDM and PVC (TPE) are most often used. The greater the thickness of the seal, the better the performance of the PVC window. In plastic windows, we can find support and glazing gaskets. They can be supplemented with an additional gasket, which will contribute to increasing the thermal insulation of the window and better noise suppression. People who live on a busy street should consider choosing a plastic window with soundproof glass. They are characterized by increased acoustic insulation, so you can be sure that it will effectively suppress sounds coming from outside.
