FORIS 501

It is a real five-chamber system. In spite of the location where horizontal cross-section of the profile is made, five chambers are always visible. Installation depth or the FORIS 501 system is 72 mm, which makes it possible to achieve perfect insulation parameters owing to perfectly designed layout of internal chambers and optimal adjustment of wall thickness. Results of tests that were carried out by well-renowned laboratories confirmed that the U-factor for window profiles is only Uf= 1,3 W/(m2xK).

Not only does the FORIS 501 system boast with technical parameters but also unsurpassed aesthetic features of windows that are made from profiles being up to the most demanding requirements of contemporary designers. Characteristic shape of window profiles perfectly proves itself for all the building types.
