Tongue and groove floor boards

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.
