Viking WarmSpan is a warm-roof-on-steel roofing system for low-sloped roofs. It has been engineered in New Zealand and is the country's simplest, most energy efficient and cost-effective warm roof system.
Viking's full proprietary, BRANZ Appraised WarmSpan system is made up of three components: a wide-spanning steel tray roof deck that also forms the vapour barrier; Kingspan Polyisocyanurate (PIR) rigid insulation panels are adhered on top, waterproofed with one of Viking's membrane systems.
Viking WarmSpan is not just a roofing system. It is a tool that provides building owners and architects with a fully-engineered; energy efficient low-slope roof system; facilitating a smarter method for a design and construction.
Viking WarmSpan 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 centered 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.
