The construction of the door and window systems with a thermal barrier MB-70HI is based on well-proven, well developed and highly appreciated base systems MB-70.
The thermal insulation performance of frames of this system is considerably higher than the insulation performance of base systems. The value of heat transfer coefficient Uf for constructions of the MB-70HI system - depending on the applied profiles and accessories – ranges between 1.11 and 2.3 W/m2K.
