Choose a BS1088 board that handles wet, demanding environments. We cut each sheet to your measurements, so you reduce waste, speed up installation, and get a perfect fit the first time.
18mm thickness adds stiffness and strength, so floors, decks, and structural panels feel solid. Because it uses durable hardwood veneers and waterproof bonding, it resists delamination, swelling, and warping. As a result, your project stays straighter for longer.
