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 non-loadbearing 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/partitioned wall conditions.
