The Aluprof MB-86US is a unique window system that combines the outstanding thermal and acoustic insulation of the standard MB-86 series with an enhanced aesthetic.

It is characterized by its concealed sash, meaning the outer profile of the opening vent is hidden behind the frame, achieving a clean, uniform glass surface from the exterior.

Aesthetic Appeal: The final appearance provides a clear perspective with a minimal sightline, achieving an elegant glass facade look.
Thermal Performance: Meets all requirements for energy conservation and environmental protection.
Versatile Application: Applicable to a wide range of window options including shop windows, porches, spatial structures, and large renovation projects.
Insulation Varieties: Available in three variations—ST (Standard), SI (Super Insulated), and AERO (utilizing aerogel insulation)—to match precise thermal needs.
