KÖMMERLING InVitra windows are available in two thermal versions:
- KÖMMERLING InVitra ® E with reinforced steel and two-chambered pane, coefficient Uw to 0,75 [W/m²K] (reference window 1230x1480mm)
- KÖMMERLING InVitra ® P with insulating foam of internal chambers and also panes installed using ‘dry glazing’ method with a coefficient of Uw to 0,69 [W/m²K] (reference window 1230x1480mm)
KÖMMERLING InVitra allows for the construction of energy-efficient entrance and terrace doors of large dimensions.
Construction of InVitra windows is based on profiles of 6 chambers with a depth of 70 mm.
InVitra System with a depth of 70 mm has the same thermal parameters of passive and energy efficient profiles with depths of 80-90 mm.
Modern three-seal system MD was designed to achieve maximum tightness. The width of the chamber glazing allows for the use of the warmest pane with a width of 52mm.
