System MB-86

The warmest system to use in energy-saving buildings

System MB-86


The new Aluprof MB-86 window and door series have been designed to offer outstanding insulation properties. It meets the increasing requirements from the legislative and general market demands for the enhanced energy saving construction of new windows and door systems, the standard for this frame is: 77 mm, for the sash: 77 mm (door) or 86 mm (windows). In Order to get the best thermal parameters  its best to use wide glass pane packets, that in this system can have the thickness of 67 mm. Offered in three varieties ST, SI and AERO it is the first aluminum system to employ silica aerogel, the nanoporous material that has a very high proportion of free void volume compared to conventional solid materials. Its high pore volume, low solid content, and torturous path amorphous structure give rise to low values of thermal conductivity. Therefore the system features the industry leading thermal performance. In addition it also features exceptional rate of profiles inertia that allows for greater windows in size (up to 1400 mm width and 300mm height). Furthermore  the sash for entrence doors can weight up to 200 kg



This system uses a really interesting solution, the possibility of hiding the hinges behind the profile of the windows outer frame, and the surfaces of mounted glass panels in the active and fixed profiles are on one plain.  Thanks to that, the external opening and fixed panels look identical and make the construction look slender and light. The system MB-86US is often choosen by architects and designers.
