Plywood is a type of engineered wood made from thin layers of veneer glued together. In this context, the plywood is sized at 8 feet by 4 feet (1220mm x 2440mm) and comes in thicknesses of 16mm, 17mm, and 18mm. It features a printed film in black and brown and is bonded with moisture-resistant (MR) glue or waterproof (WBP) glue. The core of the plywood is made entirely from poplar wood, which contributes to its strength and durability.
