Aluminium windows and doors system MB 45

The system is primarily used for interior architectural elements, such as various types of partition walls, windows, doors (including sliding, swinging and automatic doors), vestibules, shop windows, counter booths, display cases, and others. It is also the basis for special solutions: MB-45D smoke-proof partitions and doors, and the MB-45S groove-fitted door. It also permits the installation of doors and external glazing, where thermally insulated profiles are not required.

MB-45 / MB-45D


The basic MB-45 system includes profiles and accessories with optimal shapes that allow lightweight, durable and functional designs. Based on the system, it is also possible to install smoke-proof doors (Sm class), as per standard PN-EN 13502-2:2008.



The MB-45S system is used to install doors equipped with aesthetic and at the same time east-to-fit groove hinges.
