Durolite is manufactured in a range of tints and specifications to suit customer requirements.

Durolite FireGuard

Durolite FireGuard 3 (FG3) has a bromine free formulation, has been developed to provide a natural lighting sheet, while meeting the fire requirements of the New Zealand Building Code (NZBC)
The internal surface finish has been fire tested for spread of flame in accordance with ISO5660 parts 1&2. Durolite FG3 has achieved a group 3 number
Products used in construction of all new buildings are required to meet the performance criteria set out for these different fire group numbers

Durolite HeatGuard

The technologically advanced Durolite HeatGuard range is specially designed to reduce the heat transmitted into the building through natural lighting sheets while still providing a high level of light. The higher the number the less heat it transmits.

Durolite HG4 and Durolite HG8 have infrared reflecting additives in the gel coat which reduce the heat transmitted without losing light transmission. When this energy efficient product is used as roofing or cladding in commercial buildings, costs for cooling and lighting are reduced
Durolite HG4 is 28% more efficient in reducing heat whilst still letting natural light through
Durolite HG8 is 36% more efficient in reducing heat whilst still letting natural light through than an opal tinted sheet
