MB 86


The MB-86 window and door system is a product with very good parameters, offering the possibility to satisfy various user needs.

The construction of its sections has 3 options depending on the requirements of thermal energy saving: ST, SI and AERO. MB-86 is the first aluminium window and door system in the world to use aerogel, a material with excellent thermal insulation properties. The advantages of the MB-86 system also include the high durability of profiles, making it possible to construct structures of large dimensions and weight.

  • wide thermal breaks with a new shape, allowing the use of an additional partition in the profile insulation zone
  • two-component central seal perfectly seals and thermally insulates the space between the leaf and frame
  • a wide range of sections guarantees obtaining the required aesthetics and durability of the structure
