Technical specification

MB-86 is the first aluminium window and door system in the world to employ aerogel – material with excellent thermal insulation. The advantages of MB-86 also include high profile durability, enabling to create structures of large size and weight.
The features influencing the functionality and aesthetic value of structures based on MB-86 system are the following:

  • Newly shaped wide thermal breaks, which allow application of an additional partition in the profile insulation zone.
  • Two-component central gasket provides excellent seal and thermal insulation for the space between the sash and the frame.
  • A wide range of sections guarantee the required aesthetic value and structure durability.
  • Glazing strips with additional sealing option, available in three variants: Standard, Prestige and Style.
  • The profile shapes adjusted to assembly of various types of lock fittings, including hidden hinges.
  • A wide range of glazing allows to apply all available types of window panes, including two-chamber, acoustic and anti-burglary window panes.
  • The profile dehydration is available in two variants: traditional or hidden.

Panel doors, which provide a variety of attractive options and are able to meet the expectations even of the most demanding clients, can also be based on MB-86 system.



Window panes

Glazed unit is a hermetically sealed system of glass panes separated from one another, integrated along the perimeter with space bars andsealed with a sealant.Space between glass panes, referred to as cavity, is filled with air or noble gas.
Cavities can be used for installation of decorative dividers. Characteristics of glazed unit can be freely modified by using suitable types of components and coats as well as suitable number and width of cavities between glass panes.

Glass units types

  • low emission
  • acoustic
  • solar control
  • fire resistant
  • safety and security
