Glasses for Passive Houses

The glass used in MARSHALL doors and windows also has an excellent thermal insulation value as standard (Ug = 1.0 W / m2K) due to the noble gas filling (Ar) and the soft metal coating (LowE). You can choose a special three-layer glass (4Le-12Kr-4-14Kr-4Le), which has extreme thermal insulation properties (Ug = 0.39), in which the glass is filled with Krypton gas. In the case of passive houses, the inflowing solar heat plays a vital role in winter, the glass made for the passive house provides excellent thermal insulation, but at the same time, it allows the energy of the incoming sun to come through unhindered. Using some shade is almost essential.
