GERDA has expanded its doorset portfolio with the latest NEW selection of the GERDA NTT REVO doorset range. This range, depending on which options are chosen, can achieve different levels of thermal insulation.

For the Air Glass line, we offer two groups:
– energy-efficient doorset – NTT 60
– passive doorset – NTT 75

The energy-saving doorsets NTT REVO 60, have a thermal U value coefficient of 0,87 W/m2K using the ALUTHERM frame which offers a energy-efficient aluminum frame with heat chamber and gasket and 1,0 W/m2K with the DUOTHERM frame which offers a warm energy-efficient steel –  wooden frame with thermal perforation and gasket.

Passive doors provide maximum energy efficiencies and cost savings by allowing energy to be stored inside the room.  The NTT REVO 75doorsets doors are characterized by the coefficient of heat transfer, dependent on your choice of frame, from 0,77 W/m2K  to 0,93 W/m2K.
