Tongue and groove floor boards

Unbranded

P5 Moisture Resistant Chipboard Flooring is a structural flooring panel widely used in UK construction for residential, and some commercial, floors. This panel option is 22mm thick and has interlocking tongue and groove edges. This provides a tightly jointed floor panel system that helps reduce movement when fixed correctly.

Tongue and groove floorboards are commonly used for structural flooring in both new builds and refurbishments. Their interlocking edges provide a tight, stable fit, reducing movement and limiting gaps. Builders use tongue and groove flooring in domestic and commercial projects, including subfloors, loft boarding, and modular builds. This profile has a long history in joinery, but modern use focuses on engineered products that save time and reduce waste on-site. 
Available products include softwood and hardwood boards, moisture-resistant chipboard, and treated panels for humid environments. Many are compatible with nail-down, screw-fix, or adhesive installation methods. Most builders select board type based on load requirements, moisture exposure, and project budget. You’ll also find pre-grooved options designed for underfloor heating compatibility or acoustic performance.
