This edition incorporates changes to allow for the provision of 2.00 mm diameter of wire for safety mesh.
Plastics building sheets are installed using the normal procedures for other types of building sheets but with certain modifications to fixing techniques because of the inherent properties of the material. The purposes of this Standard are to reinforce general safety rules in relation to sheet installation and to highlight the differences in fixing techniques required for plastics sheets as compared with those used for sheets of other materials.
First published as AS 2424-1981. Second edition 1991.
This Standard sets out procedures for the installation of plastics building sheets for walls and roofs and for the design of plastics roofing systems.
The Standard is primarily intended to apply to the use of plastics building sheets complying with AS 2376, Parts 1 and 2.
NOTES:
1: The sheets do not contribute to the structural or load-bearing capacity of the structure and due allowance should be made to the surrounding structure to compensate for the opening areas. For applications where structural design requirements must be satisfied, reference should be made to the design and testing provisions of AS 1562 for roofing without transverse joints.
2: For use of the sheets in abnormal environmental conditions, the advice of the manufacturer should be sought.
