Reliable window series with a basic depth of 70 mm. Fulfils 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 a very economical price.                                                 

• Standard windows thermally insulated with good insulation of Uf = 1,9 W/m2K. Thermally and structurally optimised Winglet insulators with high-strength PA 6.6 fiberglass technology

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