MB 77

Aluprof MB-77HS is a lift-and-slide system for patio and balcony doors with excellent thermal insulation of 0.84 W/(m²K), meeting the strict standards of energy-efficient construction. It is the most popular lift-and-slide door in the Aluprof range; various infills, thermal breaks and accessories enable excellent thermal and acoustic parameters. Wind load class C4 to EN 12210 guarantees structural stability even in strong gusts. Slim, light profiles and large glazing areas provide plenty of daylight; the barrier-free (zero) threshold and slim mullion offer comfortable access to the balcony, terrace or garden. With the lift-and-slide mechanism, the sash is slightly raised by the handle movement and then glides with little resistance on the running tracks. Available in two thermal variants (ST and HI); large doors with single- or double-chamber insulating glass are possible, and constructions over 3 metres are operated safely by the "Comfort close" mechanism. The concealed "HS e-Power" automatic drive with intelligent obstacle detection and a safe load switch fits into the smart home concept; the optional compensation profile compensates for ceiling deflections of up to 20 mm. High compatibility with MB-86 enables shared fabrication components; glazing beads in three variants: Standard, Prestige and Style.
