The MB-86 Casement outward opening window system with a thermal break forms a part of the MB-86 system designed to execute elements of architectural external development, e.g. different types of fixed and outward-opening windows, porch enclosures, shop windows and spatial structures featuring high thermal and sound insulation performance, as well as tightness to water and air infiltration. The system meets all the requirements in respect of energy efficiency and environmental protection. The parameters of windows based on the MB-86 Casement system exceed the most stringent applicable regulations and standards.
