The RMPP Tongue & Groove P5 Chipboard Flooring is a high-performance structural flooring solution designed for use in both domestic and commercial construction. Manufactured from high-density P5-grade chipboard, these boards are moisture resistant, making them ideal for use in humid conditions, including bathrooms, kitchens, and new-build environments before windows and roofs are fully sealed.

Each board measures 2400mm x 600mm, providing a large coverage area with fewer joints, while the Tongue & Groove (T&G) edges on all four sides ensure quick, secure, and gap-free installation. The T&G profile allows boards to easily interlock, creating a smooth and stable subfloor thats ready for carpet, laminate, vinyl, or tile finishes.

Frequently Asked Questions (FAQ):

Q: What does P5 grade mean?
A: P5 is a structural grade of chipboard that is high-density and moisture resistant, designed for load-bearing flooring in humid conditions.

Q: Can this flooring be used before the building is watertight?
A: Yes. P5 chipboard is suitable for use during construction before the building is fully sealed, though it should not be left exposed long-term without protection.

Q: How is the T&G design beneficial?
A: The Tongue & Groove edges allow the boards to interlock, creating a stable, squeak-free, and gapless floor surface that resists movement over time.

Q: Do I need to treat or seal the boards before installation?
A: For best performance, especially in wet construction conditions, it’s recommended to use joint sealant or PU adhesive on the T&G edges during installation.

Q: Can I tile directly on top of chipboard?
A: While chipboard can be tiled over, it must be sealed and properly prepared or overlaid with a suitable tile backer board to prevent movement and moisture issues.
