The MB-104 Passive thermal barrier window and door system, with the highest level of thermal insulation, meets all the requirements imposed on the elements used in passive constructions.


  • windows with Passive House Institute Darmstadt certificate for versions MB-104 Passive SI and MB-104 Passive Aero
  • doors with Passive House Institute Darmstadt certificate for version MB-104 Passive SI+
  • excellent thermal insulation performance for the open window: Uw starting with 0.53 W/(m2K) and for U doorsd starting with 0.62 W/(m2k)
  • above standard sealing and insulation parameters
  • wide vitrification area, up to 81 mm
  • exterior doors available in both glazed and panel versions – ideal as an entrance door in a modern home

On the basis of the MB-104 Passive system, panel doors can also be executed, which give rich aesthetic possibilities and can meet the expectations of the most demanding customers.

General characteristics

This system helps to manufacture elements of exterior architectural constructions, e.g. various types of windows, doors, vestibules and spatial structures, characterized, in addition to excellent thermal insulation, by very good sound insulation, water and air tightness, as well as by high structural resistance.

The structure of the profiles in the MB-104 Passive system has two variants, depending on the thermal energy saving requirements: SI and AERO.

The parameters of the windows and doors built with the elements of the MB-104 Passive system exceed the current requirements of the strictest regulations and norms in force, therefore the MB-104 Passive system is a system dedicated to energy efficient and passive constructions.
