MB-78EI DPA
The MB-78EI DPA system is designed for the construction of fire-rated partitions with automatic sliding single- and double-leaf doors, achieving fire resistance classes EI15 or EI30.
The system is based on the well-established MB-78EI system, widely used in numerous projects, from which most of its components are derived. Its construction relies on three-chamber aluminium profiles with a construction depth of 78 mm and a 34 mm thermal break, ensuring reliable fire performance combined with good technical parameters.

Fire-resistant insulation elements are installed inside the internal chambers of the profiles and in the insulating spaces between the profiles, while additional insulation components and intumescent strips are applied on the external surfaces.
The system allows the use of glazing bars (muntins) in the glass. The construction technology is analogous to the base system, as in MB-78EI, and the fire resistance of doors and partitions with doors is maintained both in the event of fire from the outside and from the inside.
In MB-78EI DPA constructions, drives from well-known manufacturers can be used to handle appropriately high loads. The sliding door drive can be mounted either to the system partition or directly to the wall.
