Firewall Systems Fire protection design guide using steel wall cladding The use of insulated profiled steel cladding sheets is common practice for external wall constructions on a variety of different building types. However, in certain situations these walls are required to provide fire protection and in these instances specific Building Regulations have to be complied with. Corus Panels and Profiles offer a range of nonloadbearing fully insulated fire resistant wall cladding systems available to meet Building Regulation requirements for one hour and four hour rated external boundary walls and one hour separating/partitional wall conditions. This publication has been produced to offer guidance on the methods developed for fire containment when using our coated steel cladding products. General Construction Requirements Support Structures Sheeting Rails To accommodate the thermal expansion generated during fire all sheeting rails must be fixed to support cleats with slotted holes and bolts used must have both steel and plastic low melt washers under the head. The rails should be positioned to create maximum support centres for the firewall not greater than 2m. Allowance must be made for expansion in the rail length and span condition for the rails themselves should be single but may be sleeved to achieve continuity. Structural Frame When sheeting rails heat up during a fire they cease to function as structural members. Therefore, to prevent the wall moving downwards under its own self weight either a support at the head or base of the wall is required. All Corus Panels and Profiles firewalls can be designed to be supported from eaves beams/stanchions or rafters and posts if situated on a gable end. However, these elements must be protected using conventional fire protection materials to give the same period of fire resistance as the firewall. Cavity Barriers Where a cavity is created within the wall construction cavity barriers are required to be introduced at positions identified by Building Regulations Approved Document B. On firewalls which use non-combustible mineral fibre insulant and where the design allows the quilt/board to effectively seal the cavity against the steel sheeting no additional barrier is necessary. However, on systems where the design incorporates an air gap a cavity barrier is required positioned to the full height of the wall at intervals not exceeding 20m. The basic technical performance requirement for a cavity barrier is that it must maintain integrity for 30 minutes and provide at least 15 minutes fire insulation as determined by test in accordance with BS476 Part 22. Cavity barriers should be fixed in a manner that prevents displacement under normal service conditions or in a fire. 16 Firewall Systems
