Tongue & Groove Board
Tongue and groove OSB board is made for sheet flooring and other jobs where the board edges need to lock together securely. The interlocking profile helps create a stable surface, reducing movement between boards once fitted. You can use it for flooring decks, loft boards, roof decking, and more where added edge support is useful. At Builder Depot, our tongue-and-groove OSB3 boards give you a strong sheet option for structural projects in humid conditions.
