The MB-78HI system is used to make internal or external fireproof barriers with single or double doors with fire resistance certificate for class EI15, EI30, EI45, EI60 or EI90, according to PN-EN 13501-2: 2010.

The construction of the MB-78EI system is based on thermally insulated aluminum profiles of 78mm depth. High temperature resistance is ensured by special fire-resistant inserts of GKF or CI introduced into the internal chambers of the profiles and into the insulation space between. All additional accessories and connector are made of steel. Due to its properties, optimal cost or compatibility with other window and door systems from ALUPROF, it is a very popular product in its class and is widely used on the construction market.

The doors of the MB-78HI system can be mounted individually, within larger glazed structures or partitions, as well as in the facades of fire-resistant systems: MB-SR50EI or MB-SR50N EI. This type of construction, with single and double doors, have been successfully tested in a notified laboratory, obtaining fire resistance classes: EI30 and EI60.
