A nice and steady temperature involves significant energy savings all year round.
All Windows QFORT have high thermal insulating properties, responding to the needs of a sustainable living.
The overall heat transfer coefficient U is the value of a constructive element (wall, window, door, etc.) and indicates how much heat passes through that element. The closer the coefficient U is low, much less heat loss and better thermal insulation of the building element.
The Ug (g = glass = glass) represents the U-value of double glazing, Uf (f = frame =frame) the thermal transmittance of the frame, and Uw (w = windows = window) the thermal transmittance of the entire window frame (frame + door + insulating double glazing).
From the chart below you can easily deduce the plus of comfort and the energy savings obtained by choosing Windows with a low coefficient of insulation.
