Alupruf sliding doors

MB-77HS

The MB-77HS lift-and-slide door system offers a seamless transition to your balcony, terrace, or garden. Exceptional user comfort is ensured by features such as a barrier-free (zero) threshold and a slim central mullion.

With a wide selection of configuration options, MB-77HS allows for creative, tailor-made designs. Whether prioritising aesthetics or functionality, this system gives you the freedom to realise your vision.

In a lift-and-slide system, the door leaf first rises slightly above the track when the handle is turned, reducing friction and enabling effortless movement along the guides. The result is exceptionally smooth operation.

MB-77HS – Outstanding Performance

MB-77HS delivers excellent thermal and acoustic insulation, combined with high weather tightness. It is available in two versions—ST and HI—offering different levels of thermal performance. This system meets the most demanding requirements for its class.

Its profile design enables the creation of large glazed doors with either double or triple glazing units, making it ideal for detached houses, luxury apartments, and hotels alike.

An optional compensation profile can reduce potential slab deflection by up to 20 mm. Automation options are also available, making MB-77HS a perfect fit for smart home concepts.

The system integrates harmoniously with other Aluprof solutions for a unified architectural appearance—an advantage appreciated by both architects and by developers and homeowners. Its high compatibility with MB-86 allows shared components to be used during production.
