||The construction of the door and window systems with a thermal barrier MB-70HI is based on well-proven, well developed and highly appreciated base systems MB-70.
The thermal insulation performance of frames of this system is considerably higher than the insulation performance of base systems. The value of heat transfer coefficient Uf for constructions of the MB-70HI system - depending on the applied profiles and accessories – ranges between 1.11 and 2.3 W/m2K.
Enhanced thermal insulation performance is achieved due to placing special insulating inserts in the central insulating chamber, formed by connecting aluminium profiles with thermal breaks. Thus formed inserts reduce heat transfer through this chamber due to low value of heat transfer coefficient.
The central location of inserts additionally limits convection and thermal radiation. The MB-70HI doors and windows, just like in the case of the base system, find application both in individual assemblies and in aluminium facades.

DRUTEX S.A standard glazing package consists of 4 mm float glass, 16 mm spacer and 4 mm termofloat glass whereas the space between glasses is filled with gas- argon, which helps to achieve appropriate thermal insulation value.
Standard glazing packageincreased heat infiltration properties and its thermal insulation value amounts for U=1,0 according to norm EN-674.
Moreover, DRUTEX S.A. creates the possibility to choose an appropriate glazing package fully individually, in such a way that it poses even much better protection against burglary, noise as well as excessive insulation.
All kinds of DRUTEX S.A. doors and windows, which are manufactured on the basis of aluminium profiles are, in our standard offer, equipped in envelope ferrules MACO and locks KARO.
According to different types of ferrules there are following types of windows:
