A few words about the glazing of passive houses, which we use in our offerings. Many people are afraid of heat loss and low thermal efficiency of houses with large facade glazing. The problem of heat-loss is not the glazing area, but the poor technologies and materials usually used. If you use for glazing single-layer glass, in thin frames, without a snug fit, you can’t keep the heat and you will end in heating your house a lot and constantly (same thing with conditioning). To avoid all of these, it is enough to use energy-efficient, multi-glazed windows, designed specifically for passive houses and intended for maximum thermal insulation.
In our houses we use triple-glazed windows, with three layers of reinforced glass (outer layer is made of armored glass, the middle one is of UV-coated glass and the inner one is from triplex glass), that have the internal spacing filled with inert argon gas - all ensures maximum thermal insulation parameters. Heat transfer coefficient of our glazing is U=0.5W/m2K (lower value - less heat lost), which is one of the lowest possible for windows and compares to one of insulated brick or concrete walls.
Facades glazing is inserted into the profiled grooves at the factory and fixed on glue, excluding any gaps.
The KAGER prefabricated, half-timbered houses represent an ambiance between two worlds - the interior and the exterior. The large glazed surfaces of our homes (up to 85% of facade area) create the feeling of unity with nature and the lack of boundaries between indoor and outdoor habitat.
