Janisol HI

Tilt-and-turn windows and external displays are crafted from extra-slim, thermally insulated steel profiles, combining sleek design with energy efficiency.

DESCRIPTION

The Janisol HI window system is a benchmark for exceptional aesthetics and durability, meeting the highest standards in thermal and acoustic insulation, with an Rw rating of up to 46 dB. Accommodating windows up to 2.8 meters in height, Janisol HI windows are tested for burglary resistance, achieving the RC3 class according to EN 1627.

Designed for both safety and longevity, these windows excel under extreme conditions.

With triple-insulation glazing, Janisol HI windows achieve excellent heat transfer values – up to Uw 0.69 W/m²K for fixed glazing and 0.8 W/m²K for operable windows. Thanks to advanced glass-fiber-reinforced polyurethane insulators, the system also boasts outstanding static performance and achieves top marks in system tests (air/water/wind).
