MB-86 ST

Window and door system with thermal insulation

The MB-86 window and door system is a product with very good parameters, which allows the various needs of users to be satisfied. Its sections are available in 3 design variants depending on the required thermal energy saving: ST, SI and AERO. MB-86 is the only aluminium window and door system in the world where aerogel is used – a material with excellent thermal insulation. The advantages of the MB-86 system also include the high durability of the profiles, which allows constructions with large overall dimensions and weight to be made. 

Features that affect the functionality and aesthetics of constructions made in the MB-86 system are as follows:

  • wide thermal breaks in a new shape  allowing the use of an additional partition in the profile insulation zone
  • a two-component central gasket to perfectly seal and thermally insulate the space between the sash and frame
  • a wide range of sections ensures that the required aesthetics and the durability of the construction is achieved
  • glazing beads with additional sealing, available in three variants: Standard, Prestige and Style
  • profile shapes adjusted to use various types of multi-point locking including, but not limited to, concealed hinges
  • a wide range of glazing allows the use of all common types of panes, including two-chamber acoustic or anti-burglary 
  • profile drainage available in two variants: conventional or concealed
