High-tech isolators help steel range achieve low U-values


STEEL systems specialist, Schueco Jansen, has introduced a range of steel windows and doors that can achieve ultra-low U-values thanks to a newly developed isolator made from glass fibre-reinforced polyurethane.

The thermal efficiency of the Janisol HI systems is matched by high structural strength making them ideal for a wide variety of applications.
The Janisol HI steel window is available with turn-tilt and side-hung opening vents or fixed glazing, achieving impressive Uw values of 0.8 W/m2K and 0.69 W/m2K respectively. The dimensions of a standard 90 mm deep opening vent can be up to 2800 mm in height with a total weight of up to 180 kg.
Different infill unit thicknesses up to 67 mm allow the use of triple-glazing and burglar-resistant glass, while its slimline external face-width and a wide variety of coating options mean that a Janisol HI window can meet the highest possible specification for functionality and design.
The Janisol HI steel door combines mechanical stability with high thermal insulation properties in one single steel profile system, so it is well-suited for locations such as heavily trafficked areas in busy public buildings.
As with the Janisol HI window, the steel door benefits from the glass fibre-reinforced polyurethane isolator, achieving UD values of up to 1.0 W/m2K. With a basic depth of 80 mm, infill unit thicknesses of up to 57 mm can be used with triple-glazing and burglar-resistant glass.
