  • Substrate supports can be as wide as 3.6m centres, significantly reducing structural costs (versus plywood with timber supports at 400mm centres)
  • Lightweight roof assembly means less stress on the building structure
  • Tapered insulation board to promote watershed in critical areas (around drains)
  • Used with single-ply or two-layer torch-on membrane systems
  • ‘Polyisocyanurate’ (PIR board) has the best R-values in the market
  • WarmSpan is perfect for low-risk membrane roof design/construction methods

WarmSpan Components
