Tongue & Groove Untreated Cladding

Our 120mm x 12mm tongue and groove boards are a versatile and reliable solution for a wide range of interior and general building projects. Cut with precision-profiled edges, this tongue and groove cladding fits together securely, creating a strong, seamless finish that looks clean and professional once installed.

Each board features an 110mm effective coverage and a smooth, planed finish, making it ideal for projects where both appearance and performance matter. The tongue and groove design helps to minimise movement, improve alignment, and deliver a robust fixing compared to square-edged boards.

Supplied untreated, this tongue and groove cladding allows full flexibility in how you finish your project. You can paint, stain, oil, or apply preservatives to suit your design preferences and the environment in which it will be used. This makes it especially popular for interior wall and ceiling cladding, feature walls, sheds, garden rooms, workshops, and general joinery or DIY applications.
