Janisol Primo windows

High insulation with slim profiles

With an installation depth of only 60 mm, the thermally broken steel profiles achieve excellent heat insulation values and thus make an active contribution to environmentally compatible, sustainable building. The assembly and manufacture of Janisol Primo and combination with Janisol systems are simplified by the use of identical profile cross sections.
