Product description

Full fire safety range
The Janisol 1 system for windows and fixed glazing as well as the systems for doors and fixed glazing round off the fire safety product range. The system meets fire resistance class E/EW45 for window applications as well as E/EW30 for fixed glazing. The window has an installation depth or 60 mm (window frame) or 64 mm (window casement) and has the same face as the Janisol window. It also impresses thanks to its simple and efficient processing.

The thermally insulated door and window systems of the Janisol series in steel or stainless steel impress with excellent U values (thermal transmittance) and feature narrow face widths. The Janisol series is suitable for dry and wet glazing, while the door systems are also available with easy-access thresholds. Whether in public buildings, residential construction or renovation projects, the wide Janisol range with its differentiated, combinable profile series will meet the most demanding of requirements for thermal insulation. The Janisol systems are also at the forefront in terms of security, mechanical strength and durability.
