The art of heating.

GLASTHERM® offers more comfort and warmth than any other insulation glass, although there is no perceptible difference from other insulation glasses. GLASTHERM® is a heating glass, not only does it preserve heat but it generates it.

The heater is made of a conductive metal coating on the inside of the insulation glass. This coating is placed in the cavity between two glass panes, thus protected, invisible and in no need of any particular care or maintenance.

The advantages are obvious: No cold air is coming in from the window pane and GLASTHERM® fills the room with comfortable warmth instead, just like sunshine. The efficiency of this glass heater is astonishing: Often additional radiators are not necessary.
