MB-86 - Sonarol


The MB-86 window system developed by the renowned ALUPROF brand is an all-rounder when it comes to different user needs.


  • A wide selection of sections helps achieve the designed look, feel and strength of the structure.
  • Wide thermal breaks with a revised geometry that help fit an additional partition within the thermal insulation of the profiles.
  • Two-component middle weatherstrip provides an excellent seal and thermal insulation of the void between the sash and the frame.
  • Three versions of glazing beads available: Standard, Prestige and Style.
  • The profile shapes can accommodate different types of multi-point locking fixtures, including concealed hinges.
  • A wide range of glazing options enables installation of all commercially available double glazing units, sound-proof units and/or anti-burglary units.
  • Two versions of profile drains available: traditional or concealed.


The design of MB-86 sections is available in three versions which vary in energy-efficiency ratings: ST, SI and AERO. MB-86 is the world’s first aluminium window and door system to use aerogel, a material with a nearly-perfect thermal insulating power. Other advantages of the MB-86 system include a high strength of the profiles, which makes large and heavy structures viable.
