Lift-and-slide door is the perfect integrating element that connects rooms or winter gardens with external spaces. It provides a convenient exit to the balcony, terrace or garden. When in the open position, the door does not take up space inside the room, whilst enabling a very good contact with the environment which further increases the comfort of use. The MB-77HS system is one of the best products and meets all the requirements for this product group. It has two different construction variants with different thermal insulation: ST and HI. The construction of profiles allows for making exclusive doors of large dimensions, filled with single or double-chamber glass, and the materials and technical solutions used help to achieve a high degree of thermal and acoustic protection. Due to its characteristics, the system can be used in various types of buildings: individual buildings, hotels or apartments.

• slender and robust profiles allow the construction of low threshold doors with leaf weight up to 400 kg, height up to 3.2 m and width up to 3.3 m
• possibility of making 90 and 270 degrees corner doors with a movable mullion
• a wide range of glazing options, allowing application of double or triple glazed units combined with thermal breaks as well as additional
• inserts, enable achieving high thermal and acoustic insulation of the door.
• for aesthetic values glazing beads come in three options: Standard (rectangular), Prestige (rounded) and Style (shaped)
• closed shape of glazing beads and anti-jemmy details provide enhanced security properties without altering any
• essential constructional elements of the door
• unique gasket designs, together with quality fittings, ensure top end
• weather and air tightness performance
• profiles adapted to accommodate a number of manually or automatically operated fittings available on the market
• possibility to drive the doors with automatic “HS-Master” mechanism controlled with a push-button or remote control
• large degree of compatibility with the MB-86 system creates an aesthetic combination of the MB-77HS doors with windows, and using the same
• components in the fabrication process
• a wide range of colour schemes allows for arrangement of doors to meet any individual requirements
