Thermally insulated window and door system

The M-86 is the world's first system of aluminium windows and doors, where an aerogel is used - a material with excellent thermal insulation characteristics, distinguished by the best documented thermal insulation values. The window and door solutions in which they are used guarantee the highest thermal comfort.

High quality, great savings

The stronger the thermal insulation of windows and doors, the greater the savings they can generate due to the reduced heating costs. The M-86 system allows to scale these savings, giving you the choice of three thermal variants:

M-86 ST

System with thermal insulation coefficient from 1.39 W / m2K for windows and from 2.16 W m2K for doors.
These are the parameters required by the norms for classic joinery.

M-86 SI

System with thermal insulation coefficient from 0.92 W / m2K for windows and from 1.76 W / m2K for doors (and from 1.49 m2K in M-86 SI + version).

These parameters allow the use of window and door systems in buildings of higher energy standard. EU standards assume that, from 2021, the heat transfer coefficient of windows placed on facades will not exceed 0.9 W / m2K. The M-86 SI window system is therefore similar in terms of insulation parameters to the new building standards set by the EU legislation.


System with thermal insulation coefficient of 0.57 W / (m2K) for windows and 1.22 W / (m2K) for doors.

Such good parameters allow to use the system in energy-efficient construction.

The high thermal insulation of window and door constructions is not only due to the use of aerogel as an insulating material, but also wide thermal inserts of new shape, allowing the use of an additional barrier in the insulation zone of profiles. The two-component central seal accurately seals and thermally insulates the space between the sash and the frame.

Reliability and aesthetics

Windows and doors in the MB-86 system are characterized by high strength of profiles, allowing for construction of large dimensions and weight. The joinery of the components of this system is extremely durable, among others due to a large range of profiles.

The MB-86 enables the construction of both classic windows and non-standard glass constructions of different dimensions. It is possible to adjust the windows to a variety of architectural styles, among others due to the use of glazing bar in three variants: Standard, Prestige and Style. Profile shapes have been adapted to fit different types of hardware, including hidden hinges. Under the system, you can use a variety of glass, including two-chamber, acoustic and anti-burglary, and also make panel doors in various aesthetic variants.
