Softwood TGV Cladding / Matchboarding is a precision-machined softwood timber board with a tongue and groove edge and a chamfered "V" joint, used for decorative panelling and protective wall lining.

 

• Interior Wall & Ceiling Panelling: Installed vertically or horizontally to create classic feature walls, wainscoting, ceiling linings, and hallway paneling in residential homes and rustic interiors.

• Shed & Garden Room Interiors: Used to line the internal walls and ceilings of garden offices, summerhouses, workshops, and sheds for a clean, insulated finish.

• External Wall Cladding: Fitted on outbuildings, garages, and porch soffits to provide a protective, weather-resistant timber skin (when treated or painted for exterior use).

• Cabinetry & Joinery Projects: Applied as decorative backing for fitted wardrobes, open shelving units, kitchen islands, and custom timber furniture.

What does "TGV" stand for?

TGV stands for Tongue & Groove V-joint. The boards interlock with a tongue along one edge and a groove along the other, while the chamfered edges meet to form a clean, decorative "V" shadow line at each joint.

What is the difference between matchboarding and standard cladding?

Matchboarding is traditionally thinner and lighter with a decorative V-groove profile, making it ideal for interior wall panelling, ceiling lining, and cabinet backing. Standard exterior cladding (like shiplap) is typically thicker and engineered specifically to channel water away on exterior walls.

Does softwood matchboarding require acclimation before installation indoors?

Yes. Store the timber flat inside the room where it will be fitted for at least 5 to 7 days before installation. This allows the boards to adjust to the moisture levels and room temperature, minimizing shrinking, warping, or swelling after fitting.

Should I paint or stain matchboarding before or after fitting?

It is best to apply your initial coat of stain, paint, or primer before installation, including inside the tongue and groove channels. This prevents bare, unpainted wood lines from showing if the boards contract slightly during seasonal humidity changes.

How do I fix TGV boards to walls or ceilings?

Fix the boards onto horizontal or vertical timber battens (spaced 400mm–600mm apart) using lost-head nails, panel pins, or secret-screws driven through the tongue at a 45-degree angle. Secret fixing hides all fastener heads beneath the groove of the next interlocking board.

How do I calculate how many boards are required for my project?

Measure the total wall or ceiling area in square meters. Divide that area by the usable coverage area of a single board (calculated using the visible face width, excluding the tongue). Always add an extra 10% to 15% to cover cutting waste, corner trims, and end-joint offsets.
