What is F22 Bracing Plywood?
The F22 designation refers to the stress grade of the plywood under AS 1720.1 (Timber Structures) — a significantly higher bending strength and stiffness rating than the F11 grade used in general structural sheeting. This elevated rating is what qualifies F22 ply for use as a primary bracing element in timber wall frames, where it must resist lateral racking forces from wind loads acting on the building. Installed diagonally or vertically between studs and top and bottom plates, F22 brace ply forms a structural diaphragm that transfers wind and seismic lateral forces from the wall frame to the building's foundation system. The correct installation — including specific nail spacing, edge distances, and fixing patterns — is critical to achieving the rated bracing capacity, and must comply with AS 1684 (Residential Timber-Framed Construction) and the relevant engineer's specification.
Why Specify F22 Bracing Plywood?
A purpose-engineered bracing panel delivering the lateral racking resistance required for compliant timber-framed construction under the National Construction Code.
Janka Hardness — How Jarrah Compares
Jarrah's Janka hardness of 8.5 kN puts it among Australia's toughest decking timbers, providing superior scratch and impact resistance for high-traffic outdoor areas.
Ideal Applications
Residential Wall Bracing
The main lateral bracing for the timber-framed walls of houses, townhouses, and multi-family buildings that meet NCC standards.
Light Commercial Framing
This is the structural wall bracing used in light commercial buildings, offices, and mixed-use developments that are made of wood.
Additions & Alterations
Retrofitting or upgrading wall bracing in existing residential structures where additional lateral capacity is required
Cyclonic & High Wind Zone Construction
Where design wind speeds require increased bracing capacity, F22 brace ply provides the rated performance required by the structural engineer's specification
Two-Storey & Multi-Level Construction
Upper and lower storey bracing walls in multi-level timber-framed residential buildings where racking loads are transferred between floor levels
Modular & Prefabricated Framing
Structural bracing panels in prefabricated wall frames and modular building systems manufactured off-site and craned into position
