Topspan is an insulated roofdeck, combining a structural deck, PIR insulation and a metal top sheet into one product. Designed to support a choice of site applied standing seam or membrane finishes, Topspan provides a clear span capability of up to 8 metres, and is faster to install than alternative built-up roofdeck systems. The product has excellent fire resistance and is Loss Prevention Certification Board (LPCB) certified and the PIR core is environmentally sustainable as it is CFC/HCFC-free with zero Ozone Depletion Potential (ODP). The internal face of the deck is pre-finished providing a smooth clean interior appearance.
