Topspan

Topspan is a PIR insulated roof deck combining a structural deck and metal top sheet in one product. The panels are suitable for zinc, stainless steel and aluminium standing seam waterproofing systems and single-ply membranes. 
Topspan provides a clear span capability of up to 8 metres and is faster to install than alternative built-up roof
deck systems. The internal face of the deck is pre-finished with a fresh white inner coating that provides a smooth clean interior finish. Topspan is suitable for flat or curved roof applications with a convex or concave radius of 20 metres and is ideal or new build or refurbishment projects.
