Our projects

To respond to an ever-growing or increasing demand for building products featuring high insulation performance, Aluprof have designed a range door and window systems with a high performance thermal break, MB-70HI, MB-70US HI and a curtain wall window based on the MB-70CW HI system. The systems construction is based on well-proven, well developed and highly appreciated base systems of MB-70, MB-70US and MB-70CW.

Thermal insulation performance of this system is considerably higher than the insulation performance of the base systems. The value of heat transfer coefficient Uf for constructions of the MB-70HI system, depending on the specified profiles and accessories, ranges between 1.0 and 2.3 W/(m2K).

Enhanced thermal insulation performance are achieved by placing special insulating inserts in the central insulating chamber between the thermal breaks. The foam based inserts reduce heat transfer through to the chamber due to their low coefficient of heat transfer. The central location of these inserts further limits convection and thermal radiation.

The MB-70HI doors and window system, as in the case of the base system, find application both in individual assemblies and in aluminium facades. If used as an insert of a window wall, it would be best to combine such doors and windows with the system featuring enhanced insulation performance, such as the MB-SR50N HI+.

This system is available as PAS 24 constructions.
