The MB-104 Passive is a thermal break-equipped window systems that provides the highest thermal insulation performance, and meets all the requirements for passive building components.

The system is used to fabricate exterior architectural development elements, e.g. various types of windows, vestibules, and spatial structures, which are characterized, in addition to the excellent thermal insulation, by a very good sound insulation, water- and  air tightness and high structural strength.

The MB-104 Passive system's profile construction comes in two variants, depending on the requirements for thermal energy savings: SI and AERO

The MB-104 Passive-based windows parameters exceed the current requirements of the strictest applicable regulations and standards – that’s why the MB-104 Passive system is dedicated to energy-efficient and passive building.
Why MB-104 Passive?
