The NZ Metal Roof and Wall Cladding Code of Practice is a comprehensive design & installation guide, and a recognised related document for Acceptable Solution E2/AS1 of the NZ Building Code.
Roof lights can increase both the heat entering and leaving a building.
Tinted sheeting can be used to decrease heat build-up through radiation. Tinting can be coloured or translucent.
To decrease heat loss and prevent condensation, multi-skinned systems can be employed to provide insulation. In colder areas, UV-stabilised EVA copolymer film is often used under profiled skylights to minimise condensation. Where buildings are heated, or where condensation cannot be tolerated, multi skinned systems are recommended.
