The system of thermally-insulated economic doors MB-59SE.
The MB-59SE is a part of window/door MB-59S system. The structural depth of the section is equal to 50 mm. The applied materials and solution guarantee achieving high technical parameters: very good thermal insulation, high tightness against water and air, and also allow shortening the production and mounting time. It is possible to mount the standard hardware of reputable companies therein.
The MB-59SE structure is characterised by a low value of the heat transfer coefficient U – profiles fulfil thermal requirements for the material groups 2.1 or 2.2 according to DIN 4108. The system allows application of the set of glass panels of the thickens equal to 4.5 mm or 31.5 mm. The products based on this system passed numerous tests according to EN standards achieving very good results.
