Introduction
Exterior plywood cladding is available in various veneer grades and profiles. Plywood should comply with AS 2271 'Plywood and Blockboard for Exterior Use'. If a plywood cladding is structural, the manufacturer will indicate the stress grade. Plywood cladding can also provide structural bracing and roof hold-down resistance.
Plywood has standard tolerances on length, width, squareness, thickness and edge straightness. Type A bond is required for all exposed use of plywood. Type B bonds are considered only semi-durable. They may give satisfactory performance in semi-exposed situations such as under verandahs.
Plywood can be treated for protection against insect and fungal attacks.
