The A86US system is used to make different types of windows, balcony doors, porches, shop windows and spatial structures, which characterise very good thermal and acoustic insulation and high air and water tightness.

The window features that a vent profile is hidden behind the profile of the window outer frame, and surfaces of mounted glass panels in active and fixed profiles are on one plain. Thanks to that external opening and fixed panels look identical.
