Maximum insulation, minimum energy loss
MB-86N - a new generation of energy-efficient windows and doors
Thanks to wide thermal breaks and 3-chamber construction, it allows to achieve excellent energy performance, which significantly reduces the operating costs of buildings.
3 chambers
3 slots
Uf from 0.84
Durability to match large projects
Advanced profile design
Construction with a depth of 86 mm and the high rigidity of the profiles make it possible to make glazing of above-standard dimensions. The MB-86N system works well both in modern facades and in projects requiring large window or door casements.
Uf from 0.84 - one of the best values in its class
Thermal insulation at the highest level
Three-chamber construction, wide thermal breaks and the possibility of using a variety of glazing packages provide excellent thermal insulation. Depending on the version – ST, SI or SI+ – it is possible to achieve a Uw coefficient below 0.7 W/(m²K), which allows the system to be used in energy-efficient and passive buildings.
