GUTMANN GWD 070 Window Series

This is a window series with a depth of 70 mm. It fulfills the highest demands on thermal and sound insulation. Through the development of a modular system construction kit, a large number of thermally insulated to highly thermally insulated constructions can be produced at an economical price.

– Standard windows thermally insulated with good insulation of Uf = 1.9 W/m2K. Thermally and structurally optimized winglet insulators with high-strength PA 6.6 fiberglass technology.

– Highly thermally insulated premium window with a peak value of Uf = 1.4 W/m2K. This system has a 4-chambered coextruded hollow frame with a central gasket, glass rebate insulation inserts, and a 9 mm thick external glazing system gasket for thermal improvement.
