Durolite natural lighting sheets for roofs and walls provide good strength and durability for commercial building applications. Durolite is a premium grade glass fibre reinforced polyester sheet manufactured using advanced gel coat technology with an integral 100 micron thick gel coat on the top surface. It is guaranteed to transmit natural light for a period of 25 years while retaining material strength and load span capacity.
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.
Dimond Natural Lighting translucent sheeting products are manufactured to the requirements of AS/NZS 4256.3.1994 in a range of profiles, sheet thicknesses and sheet compositions to meet the light transmission, wind load and durability requirements for their intended use as Natural Lighting in roofs, walls and fences of AS/NZS 4257.
Past history of Durolite use in New Zealand indicates that provided the Dimond Natural Lighting Systems are designed, handled, stored, used and maintained in accordance with the guidelines given in this manual they will meet the relevant performance criteria in Clauses B1, B2, E2 and G7.
In addition, fire compliance with Clause C criteria is achieved with Durolite FG products, tested to verification Method C. Durolite FG3 achieves a group Number 3.
