MB-77 HS And MB-77 HS HI Lift And Slide Doors

The MB-77HS 'lift-and-slide' door is a solution for connecting interior space rooms or conservatories with an outside balcony, terrace or garden area.

The product provides both smooth and silent slide action operation. In addition, by way of its design and operation, the MB-77HS provides a space-saving opening and does not encroach on the free space beyond the internal or external confines of the frame.

Providing high weathertightness, 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 categorized as 'ST' and 'HI', standard or highly insulated.

The design and arrangement of the system profiles enable openings of large dimensions, accommodating double- and triple-glass unit compositions, which in conjunction with the constituent parts and innovative technical solutions help achieve a high level of thermal and acoustic performance.

Features and benefits:

• Durable and slender profiles enable screens of a low-threshold door of the weight of the leaf of up to 400 kg, height of up to 3.2 m and width of up to 3.3 m.

• A wide range of glazing options, allowing the application of double- or triple-glazed units, combined with thermal breaks as well as additional inserts, enables high thermal and acoustic insulation of the door to be achieved.

• Glazing beads available 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 hardware, ensure top-end weather and airtightness performance.

• Profiles adapted to accommodate a number of manually or automatically operated hardware available on the market.

• Possibility to drive the doors with automatic 'HS-Master' mechanism controlled with a push-button or remote control.

• Safe use of large and heavy doors, thanks to 'HS Speed Limiter' mechanism available in the system.

• A large degree of compatibility with the MB-86 system creates an aesthetic combination of the MB-77HS doors with windows, using the same components in the fabrication process.

• A wide range of colour schemes allows for arrangement of doors to meet project requirements.

Performance:

• Air permeability to EN 12207: Class 4.

• Wind load resistance to EN 12210: C4.

• Watertightness to EN 12208: Class 9A.

• Thermal insulation (Uf) from 1.4 W/(m²K). MB-77 HS HI from 0.84 W/(m²K) achieved with 3 x 2.9 m leaf, and glazing Ug: 0.5 W/(m²K) equipped with a Chromatech Ultra spacer.
