Thanks to a diverse range of infills, thermal breaks and additional accessories, the door can achieve excellent thermal and acoustic parameters to ensure maximum comfort for the residents. It even conforms to the requirements of class C4 according to EN 12210, which guarantees that it will be able to withstand even very strong wind gusts without losing stability.

MB-77HS – aesthetic look and user comfort for years to come

MB-77HS aluminium profiles are the perfect solution for people who appreciate comfort, safety and aesthetic qualities. Sliding balcony and patio doors not only have excellent technical specifications but are also functional and aesthetic. They are available in many different colours and can be easily matched with the style and feel of your home.

Sliding balcony doors have light and narrow profiles and large glazing to ensure excellent daylight admittance. They can also be provided with the “HS e-Power” concealed motor with a smart system that detects obstacles and a safe overload switch for enhanced user comfort.

The MB-77HS "Lift & Slide" door product is an ideal solution for connecting interior space rooms or conservatories with the outside balcony, terrace or garden area.

Providing both a smooth & silent slide action operation, it can bring the benefits of a beautiful day outside, into the living space. In addition, & by way of its design & operation, the MB-77HS is a great space saving opening & does not encroach the free space beyond the internal or external confines of the frame, without any compromise. Providing excellent weather tightness together with enhanced thermal performance, the MB-77HS complies with all of the requirements associated with this product type. Available in two different options, with regard to the level of thermal performance, the MB-77HS is further categorised as "ST" and "HI", standard or highly insulated. The design & arrangement of the system profiles enable luxurious openings of large dimensions, accommodating double & even triple glass unit compositions, which in conjunction with the constituent parts & innovative technical solutions, help achieve a high level of thermal & acoustic performance.

Due to the system properties, & rigorous performance proven through a stringent testing regime, the MB-77HS is ideally suited to many domestic & retail applications, providing a comfortable, safe working, cost effective & low maintenance solution for the end user.
