Aluprof MB-104 windows are premium windows that meet the highest standards of quality and insulation. They are based on Aluprof’s MB-104 PASSIVE system, certified by the PHI Darmstadt Passive House Institute. Thanks to their increased installation depth, they provide strength, airtightness and sound insulation. The available variants, SI and AERO, allow the windows to be tailored to individual energy-saving requirements. The SI variant with improved thermal break and central seal is ideal for those looking for a balanced solution, while the AERO with additional thermal and acoustic insulation will meet the expectations of even the most demanding users striving for maximum energy efficiency. Aluprof MB-104 windows also offer exceptional aesthetics. The possibility to manufacture them in a version with a concealed sash gives them a modern and elegant appearance, which harmoniously blends in with a variety of architectural styles. A wide choice of glazing and colours allows personalisation and customisation to create a unique character for any space.
