ex22mmx125mm T&G Tanalised Shiplap Cladding (19mm Finish)

Treated Shiplap Cladding – 125mm x 22mm, 19mm Finished Thickness

Our 125mm x 22mm treated shiplap cladding is a strong, durable timber cladding board, ideal for sheds, garden buildings, workshops, stores, cabins and general outdoor timber projects.

Machined to a finished thickness of approximately 19mm, this heavier-duty shiplap profile offers a more robust board than standard thinner cladding, making it a great choice where strength, durability and a quality finish are important.

The traditional rebated shiplap profile allows each board to overlap neatly, helping shed rainwater while creating a clean, attractive timber finish. The boards are pressure treated to help protect against rot, decay and fungal attack, making them suitable for external use.

Perfect for both trade and DIY customers, this treated shiplap is suitable for new builds, repairs, replacement cladding and bespoke garden projects.
