The door and window system with a thermal barrier MB-70HI is based on well-proven, developed and highly valued base systems- MB-70.
Frames in this system are characterised by significantly higher thermal insulation performance than in base systems. For MB-70HI system the value of heat- transfer coefficient ranges between 1,11 and 2,3 W/m2k, depending on the applied profiles and accessories.

Advantages of the profile:

The increased performance of thermal - insulation is obtained by placing special insulating inserts in the central, insulation chamber which is made by connecting aluminium profiles with thermal breaks. The inserts, thanks to low value of heat transfer coefficient, reduce heat transfer through this chamber. In addition to this, placing the inserts centrally limits convection and thermal radiation.

MB-70 HI windows and doors, similarly to the base system, can be used both for individual assemblies and aluminium facades.


Colours of aluminium (180 colours in accordance with RAL palette)

Window panes:

Each window by Drutex S.A. is equipped in one-chamber composite-glazing package for which DRUTEX S.A. uses Guardian glass.

Standard glazing package comprises of 4mm window pane( type float), 16 mm spacer bar of, and 4 mm soft-coated pane( type thermofloat). The surface between the panes is filled with gas-argon in order to achieve lower thermal insulation value.

Standard glazing package includes increased heat insulation with the thermal insulation value of 1,0 which is in compliance with norm EN-674.

Moreover, DRUTEX S.A. offers the possibility of individual choice of an appropriate, different glazing package so that it creates even more perfect protection against burglary noise or excessive sunlight.


All types of DRUTEX S.A. windows and doors manufactured on the basis of aluminium profiles are equipped in multi –point lockings by ROTO type ALU 500 and locks by METAPLAST CZĘSTOCHOWA.
