MB-77HS

The MB-77HS system is characterised by large dimensions of sliding system, huge panes and stable construction. The materials and technical solutions used help to achieve a high degree of thermal and acoustic protection. MB-77HS doors can be used to build 2- or 3-rail structures with a low threshold, thanks to which we obtain a very large space after opening the door. Thanks to their properties, MB-77HS doors are perfect for single-family buildings as well as for comfortable apartments or hotels.

MB-77HS – benefits

  • Two types of window frame: 2-rails/ 3-rails
  • The depth of the frame: 174 mm (with double running rail profiles) or 271 mm (with triple running rail profiles)
  • Fittings – lift & slide system: up to 400 kg
  • Maximum sash dimensions: 3300 mm x 3200 mm
  • Sash depth: 77 mm
  • Burglary resistance: RC2
  • Convenient solutions with a low aluminium threshold and a thermal barrier
  • Special shapes of the lock and glazing gasket and appropriate fittings resulting in high tightness of the door
  • The profiles adapted to the assembly of many commercially available manually and automatically locked fittings
  • Fixed accommodation possible with glass installed directly in the frame (aesthetic and economical solution)
  • Doors operated with the “HS-Master” push-button control unit
  • The “comfort close” mechanism available in the system for the operation of large and heavy doors

Depth of the frame

A very important dimension, saying a lot about sliding doors quality and functionality. The depth affects the sound insulation, thermal insulation (U-value) and stiffness of the structure. To put it simply: the bigger the depth, the warmer the sliding doors.

Thickness of the glazing unit

A glazing unit is a structure consisting of two, three, or even four panes of glazing separated from each other by a distance frame, sealants and vapour-absorbing gas (argon \ krypton). The thickness of the glazing unit is the overall measurement, from the outside glass surface to the inside glass surface. The average double glazing thickness is about 24 mm while triple-glazed windows are 42 – 48 mm in thickness on average. The number of panes in a glazing unit affects the improvement of the U-value parameter

Wind resistance

It is one of the most important properties of windows and doors. It determines the safety of the entire structure, as it indicates the amount of pressure caused by wind that the window or door structure is able to resist without serious damage. The classification of wind-resistant windows and doors is carried out in accordance with PN-EN 14351-1. The wind load resistance of the window is described by two symbols: the number (1-5) which indicates the pressure of wind applied to the product and the letter (A-C) which indicates the amount of accepted deflection.

Water resistance

It is the capacity to avoid water leakages under wind and rain at the same time. Leakage is defined as the appearance of uncontrolled water (other than condensation) on the inner surface of the product. Obviously, the doors and windows with good waterproof performance can effectively prevent water from entering into their internal structure and – as a result – ensure a longer service life. The classification ranges from Class 0 (no test) to Class 7A for windows and Class 3A for doors.

Air permeability

It is the measurement showing how easily air can pass through a window or a door. The European Standard regarding air permeability in windows and doors is EN 12207. It classifies windows or doors according to their capability to prevent air travel through the system. This capability is measured on a scale, from Class 1 (less tightness) to Class 4 (higher tightness). A window or a door system with a higher level of air tightness is more energy-efficient, as less heated air escapes through it.
