16 x 120mm Softwood TGV Green Treated Cladding / Matchboarding is a versatile, pressure-treated timber paneling profile featuring a V-joint detail, designed for both exterior weather-resistant cladding and heavy-duty interior lining.

 

• Exterior Garden Building Cladding: Used as protective external cladding for garden sheds, workshops, garages, summerhouses, and outbuildings to create a weather-tight timber skin.

• Interior & Exterior Feature Paneling (Matchboarding): Fitted vertically, horizontally, or diagonally on internal walls, ceilings, porch linings, or soffits to achieve a decorative V-groove timber panel finish.

• Fencing & Gate Construction: Ideal for building sturdy timber privacy fencing, heavy-duty gate infills, refuse bin stores, and garden screening.

• Moisture-Exposed Internal Areas: Suitable for lining utility rooms, workshops, garages, and damp-prone indoor spaces where added resistance to moisture and rot is required.

What is the difference between a TGV profile and a Shiplap profile?

A TGV (Tongue & Groove V-joint) board features a chamfered edge that forms a distinct "V" groove line at each joint when connected, creating a decorative paneled appearance. Shiplap, by contrast, features a smooth scalloped rebate designed specifically to optimize horizontal water runoff on exterior structures.

What does "Green Treated" mean, and will the color stay?

Green treated timber has been pressure-impregnated with copper-based preservatives to protect the wood against rot, fungal attack, and insects. The initial pale green hue is a natural result of the copper treatment process and will gradually weather into a honey-brown before eventually silver-graying over time if left untreated.

Can TGV boards be installed vertically as well as horizontally?

Yes. Unlike shiplap, which is almost exclusively installed horizontally to shed water, TGV matchboarding can be installed vertically, horizontally, or diagonally. When installed vertically outdoors, ensure the tongue points into the groove away from prevailing winds, or install with tongues facing upward/outward as appropriate to prevent water trap.

What fixings should be used to install this cladding?

Fix the boards to treated timber battens using stainless steel or hot-dipped galvanized nails or screws. Standard steel fixings will react with the moisture and pressure-treatment chemicals in the timber, causing unsightly black rust streaks across the wood surface over time.

How do I calculate how many 4500mm boards are needed for a project?

Each 4.5m board provides roughly 0.50 m² of usable coverage (based on the 110mm visible face width). Divide your total surface area in square meters by 0.50 and add 10% to 15% extra for cutting waste and joint alignments.
