What Is WISA Twin B/WG Plywood
WISA Twin is a premium birch plywood panel featuring a long-grain construction with a birch face on one side where butterfly patches are permitted, and a WG back. It is manufactured using birch veneers with a spruce pine core, delivering a strong panel with reduced overall weight.
A PVA B bond glue is used during pressing, making this exterior plywood suitable for applications where durability and stability are required. The result is a plywood panel that balances strength, workability and a smooth surface finish.
