-
Profile Depth: The door sections feature a design depth of 77 mm for the casement and 174 mm for the 2-rail frame.
-
Three-Chamber Structure: Profiles within the system adopt a three-chamber structure, with the central chamber serving as the insulation chamber between shaped thermal breaks measuring 43, 42, 35, or 27 mm in thickness.
-
Dual Construction Variants: The MB-77HS HI system offers two construction variants, each differing in thermal insulation, without the need to alter the core profiles and accessories. The first variant, MB-77HS ST, features an empty central chamber between thermal breaks for lower thermal insulation. The second door variant, MB-77HS HI, incorporates a central chamber filled with a special insulation element or a barrier between thermal breaks, enhancing its insulating power. These structure variants accommodate various user needs while keeping storage and manufacturing costs economical.
-
Effective Insulation: Wide thermal breaks, polyethylene inserts, and plastic chamber profiles within the thermal insulation bands contribute to a relatively low overall heat-transfer coefficient (Uf) for frames.
-
Water- and Air-Tightness: Specially shaped cover strip and glass pane gaskets, in combination with casement fittings that facilitate secure fitting into the frame during closing, ensure excellent water- and air-tightness.
-
Burglary Resistance: Closed shape glazing beads, available in Standard and Prestige versions, enable the secure installation of infills, supporting the creation of anti-burglary constructions. EPDM positioning rollers in these beads facilitate mounting within the window or door frame.
-
Glazing Versatility: The system accommodates a wide range of pane thicknesses, from 13.5 to 58.5 mm, allowing for various types of two-chamber, acoustic, or anti-burglary glass panes.
-
Fittings Compatibility: Standard fittings grooves facilitate the use of most lift and sliding as well as sliding fittings available on the market, including options from G-U, Hautau, and Siegenia.
-
Drainage Options: The profile drainage system can be concealed or visible, featuring a decorative plug.
-
Customization: Thermally insulated profiles in both MB-77HS ST and HI versions can be powder varnished and anodized.
-
Simplified Construction: The construction technology is streamlined for efficiency, reducing manufacturing time. Instrumentation such as drilling templates, presses, or blanking dies can be used for various treatments.
-
Impressive Dimensions: The maximum overall casement dimensions significantly exceed standard values, with Hs=3.2m and Ls=3.3m. The maximum casement weight is 400 kg.
-
Compatibility: The MB-77HS HI system seamlessly integrates with other Aluprof systems, particularly MB-86, allowing for shared elements like glazing beads, gaskets, fittings, and most accessories across systems.
The MB-77HS HI system excels in providing exceptional thermal performance and adaptability, making it an ideal choice for projects that require cutting-edge technology and sustainability.
