Open to the surroundings
The MB-77 HS lift-and-slide doors provide a comfortable exit to the balcony, terrace, or open garden space.

This system enables the creation of exclusive, modern doors of large dimensions, delivering exceptional panoramic visual effects and revealing breathtaking views.
Warmth in your winter garden
The MB-7HS system meets the highest standards for this product category in terms of thermal insulation. It protects against heat loss thanks to features such as wide range of infill options, allowing for the use of single- or double-glazed units, as well as thermal breaks and additional accessories. The specially designed central and glazing gaskets, combined with high-quality fittings, ensure excellent protection against the ingress of cold air and water, the system is available in two construction variants with different levels of thermal insulation: ST and HI.
MB-77 HS ST
This is the “cooler” version of the system, achieving a frame heat transfer coefficient (Uf) from 1.4 W/m²K. It offers good performance, providing a satisfactory level of thermal protection.
MB-77 HS HI
This is the “warmer” variant, recommended for buildings with increased thermal insulation requirements. It achieves outstanding thermal performance, with Uw value starting from 0.83 W/m²K.
Functionality and aesthetics
The system is based on durable, slim profiles that allow for the construction of low-threshold doors with sash weights of up to 400 kg, heights of up to 3.2 m, and widths of up to 3,2 m. It enables the design and installation of large-scale doors that perfectly complement contemporary terrace and garden architecture. The system also allows for various door configurations, including corner doors with a movable post. Glazing beads are available in three design options: Standard (rectangular), Prestige (rounded), and Style (shaped), offering diverse visual effects. A wide range of colours ensures that the appearance of doors harmonises beautifully with both interior and exterior surroundings.
One of the system’s greatest advantages is its versatility. The profiles are compatible with a wide variety of fittings available on the market, in both manually and automatically locked versions. In addition, the MB-77HS doors are fully compatible with the MB-86 system, allowing them to be seamlessly combined with windows to achieve a consistent aesthetic, thanks to shared production and installation components.
Additional system features:
- Enhanced anti-burglary performance achieved without significant changes to the door’s construction, thanks to closed profile glazing beads and anti-lift security details.
- Automated operation using HS-Master drive, which can be controlled via a button or remote control.
- Durability and user safety even for large and heavy doors, ensured by the HS Speed limiter mechanism integrated in the system.
