Strength and water protection for wet areas
Our BWP range of block boards is made of 100% imported New Zealand pine fillers and batons of uniform dimensions, each treated individually with preservatives. They are kept in closed environments to ensure proper diffusion of preservatives into the wood.
The core and panels are made from hardwood species of timber, which makes the board extremely strong, finished with an extra-thick face.
