The Viking WarmRoof System has been appraised for use as an insulating roof on buildings within the following scope:

• the scope limitations of NZBC Acceptable Solution E2/AS1, paragraph 1.1 with regards to building height and maximum floor plan areas; and,
• on limited access flat roofs with concrete, plywood or steel structural decks subject to specific structural design; and,
• with roofs constructed to drain water to gutters and drainage outlets complying with the NZBC; and,
• with roofs constructed to suitable falls (refer paragraph 15.3 and 15.4 of the Viking Warm Roof BRANZ Appraisal); and,
• with no integral roof gardens; and,
• situated in NZS 3604 Building Wind Zones, up to, and including Extra High

The Viking WarmRoof System has also been appraised for durability and thermal performance as an insulated roofing system on buildings that are the subject of specific design with no building height restriction. Building designers are responsible for the building design and for the incorporation of the Viking WarmRoof System into their design in accordance with the declared properties and instructions of Viking Roofspec.

The Viking WarmRoof System must be installed by Viking Roofspec Licensed and Trained installers.

• Clause B1 STRUCTURE: Performance B1.3.1. The Viking WarmRoof System meets this requirement.
• Clause B2 DURABILITY: Performance B2.3.1 (b), 15 years. The Viking WarmRoof System meets this requirement. See paragraph 10.1 of the Viking WarmRoof BRANZ Appraisal.
• Clause E2 EXTERNAL MOISTURE: Performance E2.3.1 and E2.3.2. The Viking WarmRoof System meets these requirements. See paragraphs 15.1 — 15.9 of the Viking Warm Roof BRANZ Appraisal.
• Clause F2 HAZARDOUS BUILDING MATERIALS: Performance F2.3.1. The Viking WarmRoof System meets this requirement and will not present a health hazard to people.
• Clause H1 ENERGY EFFICIENCY: Performance H1.3.1 (a). The Viking WarmRoof System will contribute to meeting this requirement. See paragraph 14.1 of the Viking WarmRoof BRANZ Appraisal.
• Clause C/VM2 FIRE PERFORMANCE (of wall and ceiling linings) — ISO9705, Group 1S = highest possible rating.

• BRANZ Appraised No. 713 (2011)
• Backed by a 20-year product warranty, and for specific projects, is eligible for Viking's Full System Warranty, which covers the product and installation in one document
• Tapered panel option — maximum watershed
• The system's thermal performance helps achieve Green Star points for a building
• Viking Enviroclad and Viking Bituclad both hold CodeMark Certificates and are appropriate membrane systems for Warm Roof
• Electricity savings from the building's new energy efficiencies can amortise the reroof cost as quickly as 8 years after installation (depending on the polyiso thickness and colour of membrane)
• The rigid insulation sheets add structural integrity to the roof while the wide-sheet membrane means fewer seams and greater waterproofing integrity
• Significantly higher R-values are achieved with polyiso panel (uniformly across the entire roof; not just in parts)
• No CFCs in the manufacture of a Viking WarmRoof
