French windows

French windows in HS and HKS systems as well as According Doors, thanks to their construction, give us many glazing surfaces that can be 3m high and even a few meters wide.

With possibility to use many different glazing packages with various thermal transmittance values, these places do NOT cause any loses in thermal energy. What we gain instead is wide and comfortable exit for a terrace with a low door threshold. According Doors allow us to develop width of over 10 meters, which is more important is the fact that after opening them there are no vertical or horizontal bars. A wide variety of French doors in our offer gives you many possibilities to arrange your interior and fit it to your needs.
