MB-SR50N ELFAÇADE SYSTEM

The mullion-transom system MB-SR50N EI is intended for the construction and execution of light fire resistant curtain and filling walls of the fire resistance class EI15, EI30, EI45, EI60 according to the standards PN-EN 1364-3 and PN-EN 1364-1

• • The construction of the system is based on the load-bearing grid structure composed of vertical members (mullions) and horizontal members (transoms) of box-shape section and characteristic width 50 mm. The profiles of mullions and transoms are suitably connected with each other and form an aluminium grid structure, which is mounted to the building construction with suitable brackets.
• • In order to obtain fireproof aluminium profiles, mullions and transoms have been equipped with special fireproof inserts. A fireproof insert consists of a special-shape aluminium profile, fulfilling the function of reinforcement, shielded with panels made from fireproof materials.
