Durolite FireGuard 2 (FG2) and Durolite FireGuard 3 (FG3) - which has a bromine free formulation,  have been developed to provide a natural lighting sheet, while meeting the fire requirements of the New Zealand Building Code (NZBC).

Sheet Characteristics

The useful life of Natural Lighting products is determined by their ongoing ability to allow sufficient light into the building. The following table gives a guide for the recommended use and the expected useful life based on light transmission. The long-term performance of Durolite products is enhanced by the use of a 100-micron integral gel coat surface rather than a laminated polyester film (Maxilite).

Durability Guide
