Building Linings and NCC Fire Performance Requirements

According to the Deemed-to-Satisfy provisions of the NCC, any material that is used as a building lining must have a Group Number classification as defined by the NCC, with Group 1 being the highest possible level. This includes reflective insulation products which are used in buildings such as warehouses and commercial or industrial sheds where internal wall and ceiling linings are typically not applied. In these applications, the insulation material itself is considered the lining material, and must therefore have a Group Number classification. For materials which have reflective surfaces, such as reflective insulation, and materials that melt and shrink away from a flame, the NCC requires an AS ISO 9705 full scale fire test to be undertaken to determine a Group Number to meet the Deemed-to- Satisfy provisions (NCC BCA Vol. 1 Specification C1.10 referencing AS 5637.1).

What does Group 2 mean?

A Group 2 fire performance classification means that the product can be used in most areas of buildings apart from fire-isolated exits and fire control rooms, and some un-sprinklered corridors. Kingspan AIR-CELL InsulinerTM is the only reflective insulation product currently available in Australia which achieves a Group Number better than Group 4 (1) and can therefore be used to demonstrate compliance to the NCC fire performance requirements in warehouses and commercial or industrial sheds where conventional internal wall or ceiling linings are not applied.
