Fire-rated glazed roofs (klasa REI30, RE45; 5°- 75°; 1250 mm x 3250 mm)

The MB-SR50N EI aluminum façade system enables the construction of glazed roofs with fire resistance classifications of REI 30 and RE 45 in compliance with PN-EN 13501-2. The roof framework is built using mullion and transom profiles instead of traditional rafters and purlins, forming an aluminum structure anchored to the building with specialized brackets.

Key features include:

- Fire Protection: Dedicated firestop inserts, made of reinforced aluminum profiles and firestop boards, eliminate the need for additional steel reinforcements.

- Versatile Structure: Suitable for roof inclinations from 0° to 80°, with rafters ranging from 85 to 225 mm in depth and purlins from 65 to 189.5 mm.

- Glazing Options: Supports 36–52 mm-thick glass panels, with a maximum glass size of 2100 mm x 1100 mm. Integration of photovoltaic panels or glass is also possible.

This system provides robust fire-rated protection while accommodating flexible design and energy-efficient solutions.
