Tongue and Groove (T&G) Plywood Sheets are engineered panels designed for easy installation and a strong interlocking fit. Featuring machined edges with one "tongue" and one "groove," these sheets connect securely to create a smooth, gap-free surface. Widely used in flooring, roofing, and wall sheathing, T&G plywood provides superior stability, load-bearing strength, and long-lasting performance.

What Is Tongue & Groove Plywood?
Tongue and groove plywood sheet comprise a 'tongue' edge with a precisely engineered gap 'groove'.
When installing the boards, this tongue edge slots perfectly into the groove, making the installation process a breeze.
For additional security, the boards can also be glued or bound with screws or nails ( a method often referred to as 'secret nailing').
Overall, tongue and groove plywood sheets reduce movement and aid in preventing uneven points in sub-flooring where two ends meet.
Offering extra stability at joints, a T&G profile helps eliminate sagging, making for a rigid subfloor.
