MB 104


The door and window system with thermal break MB-104 Passive, with the highest thermal insulation, meets all the requirements for elements used in passive construction.

The system is used to make exterior architectural elements, e.g. various types of windows, doors, vestibules, display windows and spatial constructions, which, apart from excellent thermal insulation, are also characterised by very good sound insulation, water and air tightness, and high structural strength.

The construction of MB-104 Passive system sections has two variants depending on the requirements of thermal energy saving: SI and AERO

The parameters of windows and doors made of the MB-104 Passive system elements exceed the current requirements of the most stringent applicable regulations and standards, therefore the MB-104 Passive system is a system dedicated to energy-saving and passive construction.

  • above-normative tightness and insulation parameters
  • wide glazing range up to 81 mm
  • external doors available in both glazed and panel versions – ideal as entrance doors to a modern house
