TopspanInsulated Roof Deck
Topspan is a PIR insulated roof deck combining a structural deck and a metal top sheet into one product. The panels compliment zinc, stainless steel, aluminium standing seam waterproofing systems and single-ply membrane.
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 finish, providing a smooth clean interior. Topspan is
suitable for flat or curved roof applications and is available with
the Benchmark Total Guarantee, offering protection for thermal and
structural performance.
