The MB-104 Passive window and door system with a thermal break that provides the highest thermal insulation performance and meets all the requirements for components used in passive construction.

This system is used to make exterior architectural building elements, e.g. various types of windows, doors, vestibules, and spatial structures, which are characterised, in addition to the excellent thermal insulation, by very good acoustic insulation, water- and airtightness and high structural strength.

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

The MB-104 Passive-based door and window parameters exceed the current requirements of the strictest applicable regulations and standards – that is why the MB-104 Passive system is dedicated for low-energy and passive construction.

• Passive House Institute Darmstadt-certified windows for MB-104 Passive SI and MB-104 Passive Aero
• Passive House Institute Darmstadt-certified doors for MB-104 Passive SI+
• high thermal insulation for windows that can be opened U_W from 0.53 W/(m²K) and for doors U_D from 0.62 W/(m²K)
• standard-exceeding weathertightness and insulation performance
• large range of glazing – up to 81 mm
• exterior doors are available both glazed and panelled – ideal as an entrance door to a modern home

The MB-104 Passive system may also be used to fabricate highly aesthetic panel doors that meet the expectations of even the most demanding users.
