18mm P5 Moisture-Resistant Loft Boards

Built to Last a Lifetime

Unlike standard DIY chipboard or flimsy thin plywood panels, our 18mm P5 flooring is manufactured with specialised water-repellent resin binders. Each panel features precision 4-sided tongue-and-groove joints that slot tightly together, creating a seamless, flush, and rigid floor.

• P5 Moisture-Resistant Grade: Resists loft humidity and temperature shifts without swelling or warping.
• Interlocking T&G Joints: Distributes weight smoothly between adjacent panels, preventing flexing or creaking.
• Sustainably Sourced: Certified FSC-approved timber from responsibly managed British forests.
