Built-up Metal Roof

Profiling the right insulation

Used for well over five decades in the UK construction market, built-up metal roofing and cladding systems are constructed from lightweight materials such as aluminium or steel and shaped into different profiles to achieve the specified aesthetics and performance criteria. Typically consisting of a low profile inner sheet separated from a higher outer sheet, the resulting cavity must be treated to deliver the required acoustic, fire and thermal protection. 

While the non-combustible nature of stone wool insulation makes it a robust choice for fire safety, it’s actually the superior sound insulation of the material which makes ROCKWOOL an ideal specification for built-up metal roof applications.
