Therm Light

A large amount of sunlight enters the interior thanks to the low assembly height of the frame and sash profiles.

An additional middle seal improves the acoustic and thermal performance of the window.

An additional seal in the sash glazing chamber enhances the window’s thermal transmittance coefficient.

Large chambers enable proper ventilation of the profiles and easy drainage of rainwater.

Environmentally friendly due to the use of calcium-zinc stabilisers.

The Uf value for the frame/sash assembly is 1.0 W/m²K.

Available in four core colours (white, brown, caramel, anthracite) with 38 types of foils.

The Uw value is 0.72 W/m²K,
which is the thermal transmittance for a reference window* with glazing of Ug = 0.5 W/m²K.
*Reference window size: 1230 mm x 1480 mm.

Coloured cores
Profiles coloured in mass maintain an aesthetic appearance even if mechanical damage occurs during many years of window use.

Foiling
We use proven, high-quality foils that are highly resistant to chemicals, weather conditions, and temperature changes.
