Our standard window system fulfills all the requirements of a modern window and combines excellent thermal and sound insulation properties.
Using slender profile sightlines and a narrow installation depth, it can be easy used in new building and renovation projects.
The thermal insulation value on a standard window is between 0.21 - 0.23 Btu/hr-sq ft-°F but values as low as 0.13 Btu/hr-sq ft-°F are reached if the frame and sash are filled with ProEnergyTec insulation foam. It can take modern triple glazing or special functional glazing up to 50 mm thick and has sound insulation up to 46 dB.
Different U-values are possible depending on the frame - sash combination, glass and steel insert. Contact us for more details.
