Viking WarmSpan Tray System
Viking WarmSpan is a warm roof that includes a proprietary steel tray substrate, supplied by Viking, to make up a complete roof system. WarmSpan consists of a wide-span steel tray roof deck that also forms the vapour barrier with its clever flashing system. The Kingspan Polyisocyanurate (PIR) rigid insulation panels are adhered on top, and the surface is waterproofed with any of Viking Roofspec’s sheet membranes.
Unlike Viking’s WarmRoof system that is installed on an existing concrete, ply or steel substrate already in-situ (new or old), a Viking WarmSpan system has been specifically engineered and tested to comfortably exceed New Zealand’s Building Code’s minimum standards. The WarmSpan system has a spanning ability between purlins of up to 3.6m (versus the 400mm centred joists required under a heavy 17mm plywood substrate for a traditional membrane roof). This reduces a building’s overall structural cost without compromising the integrity of the building and delivers increased performance and greater durability.
Viking WarmSpan avoids using unnecessary components such as mechanical fasteners and cover-boards, producing a simple and energy-efficient three-layer system.
Components of a Viking WarmSpan system:
- Viking WarmSpan proprietary steel-tray substrate
- Kingspan Polyiso insulation panel (including tapered)
- Any of Viking’s sheet membrane systems
