The MB-70B system has been designed chiefly with the needs of the Belgian market in mind.
It is based on a well-proven, developed and valued window and door system [MB-70HI] (https://aluprof.com/producenci/oferta/systemy-okienno-drzwiowe/mb-70hi-system-okienno-drzwiowy-o-podwyzszonej-izolacji-termicznej#wizualizacja). Proper insulation of the construction is ensured by profiled thermal separators and additional insulation elements inside the aluminum sections. An important feature of the internal construction of windows and doors is the ventilation gap between the glass package and the insulation insert that functions at the edge of the pane along its entire circumference. The system allows for the construction of various window and door structures and the use of fillings with a wide range of thicknesses, so we can obtain products with very good properties, adapted to the specific needs of a given building.
System MB-70B has an ATG certificate issued by the Belgian research institute UBAtc.
