MB-104

The MB-104 Passive window and door system is an advanced solution, designed specifically for passive construction, where maximum energy efficiency is a priority. Passive House Institute Darmstadt certificates confirm the high quality and excellent thermal performance of MB-104 Passive, both for windows and doors.

MB-104 Passive offers excellent technical and airtightness parameters that provide thermal comfort and protection from the weather. The heat transfer coefficient for windows starts at 0.52 W/(m²K) and for doors at 0.62 W/(m²K), demonstrating their remarkable energy efficiency. The system also allows the installation of glazing up to 81 mm thick, allowing for a wide range of choices in terms of thermal insulation and security. Thanks to its robust construction, MB-104 Passive is able to withstand heavy loads and carry out large-scale projects.

MB-86 SI

MB-86 SI features enhanced thermal insulation, making it an ideal choice for projects where energy savings are a priority. Thanks to the use of advanced thermal breaks and an improved central gasket, MB-86 SI effectively reduces heat loss, increasing indoor thermal comfort. This variant is an excellent solution for energy-efficient and passive buildings, where minimizing energy consumption is crucial.

MB-86 AERO

MB-86 AERO is the most advanced variant of the system, using an innovative material - aerogel, which offers exceptional insulation properties. As a result, MB-86 AERO achieves the highest standards of energy efficiency, making it an ideal choice for projects requiring maximum thermal protection. It is ideal for buildings with the highest energy requirements, where the priority is to minimize heat loss and maximize energy savings.
