Wall Treatments
Tongue and Groove
Tongue and groove refers to any planking where boards interlock via a projecting tongue on one edge fitting into a groove on the adjacent board. This joinery creates seamless surfaces for walls and ceilings, whether contemporary horizontal applications or traditional vertical installations.
Beyond the technical joint, the term often describes any wood-planked wall or ceiling treatment. The interlocking construction creates stability while the visible joints add rhythm and character to surfaces.

Placement & Usage Tips
Popular for ceilings where the planked appearance adds warmth. On walls, can be horizontal (shiplap-like) or vertical (beadboard-like). Consider wood movement when installing.
💡 Pro Tip
For ceiling installations, consider engineered tongue and groove which handles humidity changes better than solid wood—this prevents gaps from opening during dry seasons.
