Windows and doors made of PVC.

Everything from a single source for 50 years now.

Do you want windows made of PVC? Good choice. PVC makes a perfect insulator and is easy to maintain, durable and ideal for recycling. Finstral has been making windows and doors of PVC for nearly 50 years now. In contrast to others, we do everything ourselves: developing frame profiles, producing insulation glass, setting installation standards. That is why our PVC windows offer advantages that can only be found at Finstral.
High-quality colours and surfaces.
High-quality colours and surfaces.
Our windows and doors are not only available in numerous high-quality colours and surfaces, the material used for our frame profiles is also always through-dyed, rather than simply using film. Textures are embossed directly onto the surface, thus making them significantly more scratch- and dirt-resistant. And our colour-resistant wood decor films are welded directly onto the frame, permanently affixing them to the profile.
As narrow as it gets.
As narrow as it gets.
Finstral window frames are always among the narrowest in their category – no matter whether you are looking for a classic or a modern frame form, whether for a new build, an old building or a renovation project. Finstral windows offer excellent views outside while letting plenty of light inside. With no compromise on thermal insulation values.
Perfect insulation.
Perfect insulation.
What does perfect insulation involve? The best insulation values for the frame profile and insulation glass, absolute air- and water-tightness and expert connection of all joints with the masonry. We can do everything; we can offer everything. What Finstral also offers: instead of buying in parts to combine, we consistently produce everything ourselves. Profiles, high-quality insulation glass, ift-tested structural joints – everything fits together perfectly with us.
Very straightforward: installation.
Very straightforward: installation.
Replacing windows? No need for major construction works. Slide-on installation requires only about two hours per window. In this case, the old window frames are cut back and faced – all without the need for masonry works. In 1978 Finstral was one of the first to use slide-on frames on old buildings: today we are the most experienced.
