OSB/3 Board Flooring Sheets | Tongue and Groove (18mm)
Product Video
Specifications:
OSB/3 Board is produced by strips and flakes of wood being coated in an adhesive resin. The specific placement of these flakes when hot-pressed produces a structured, versatile and moisture resistant panel. The T&G edging on these particular boards gives all the same qualities as standard OSB Sheets, with the added convenience of being able to easily slide and slot the boards together to create one smooth cohesive surface. The advantage that OSB/3 has over other T&G Boards made of different materials, is its incredible strength and humidity resistance, making it ideal for exterior projects or anywhere that may experience high levels of humidity and moisture, such as boiler rooms or laundry rooms.
We stock the OSB/3 Tongue and Groove Flooring Sheets in a thickness of 18mm and comes in two standard sizes:
