The MB-86 window and door system offers excellent insulation properties and is also suitable for low-energy houses. There are up to four thermal insulation options to choose from, depending on the requirements of the project. It is the first aluminum system to use a silica aerogel filled with non-woven glass fabric (in the AERO version) to help achieve superior temperature performance. The high strength profiles enable the production of structures with large dimensions and weights, as well as burglary-resistant structures.
