The profiles MB-86EI are used to produce thermally insulated fire resistant operable windows, doors and fixed windows for facades, fire resistance class EI30. The MB-86EI is based on the MB-86 system, which offers excellent thermal and acoustic insulation as well as water and air tightness. The MB-86EI system thus combines the advantages of a classic window-door system with the properties of fire-rated partition walls in terms of thermal parameters, durability parameters and production technology. A construction based on this system meets all the requirements of the applicable regulations and standards, especially energy efficiency and environmental compatibility, while at the same time ensuring good fire safety.
