Home / Products / Timber Cladding / Tongue and Groove Wall Panels

Tongue and Groove (T&G) wall panels are a classic and highly functional type of wood paneling used for both interior and exterior walls. They're designed to interlock—each board has a tongue (a protruding edge) on one side and a groove (a recessed slot) on the other, allowing them to fit snugly together like puzzle pieces.

What Makes Tongue and Groove Panels Special?
Seamless Fit: The interlocking design creates a smooth, continuous surface with minimal gaps.
Easy Installation: Boards slide into place and can be nailed, glued, or screwed—great for DIY or professional builds.
Versatile Orientation: Can be installed horizontally, vertically, or even diagonally depending on your design vision.
Durable & Stable: Less prone to warping or movement compared to traditional planks.

Interior Applications
Tongue and Groove panels are popular for:
Accent Walls: Add texture and warmth to living rooms or bedrooms.
Ceilings: Create a cozy, cabin-like feel or a sleek modern finish.
Wainscoting: Protect lower walls while adding visual interest.
Saunas & Spa Rooms: With proper wood species and treatment, they handle heat and humidity beautifully.
