Shiplap Cladding

Shiplap is a machined cladding profile for external timber cladding applications. We can machine a range of shiplap profiles for both face fixing and hidden fixing.






All dry wood species



What is Shiplap Cladding?

Shiplap cladding is a traditional style of timber cladding with a smooth finish and an overlapping or interlocking edge detail to create a waterproof façade. What differentiates shiplap cladding profiles from others is a wide ‘scoop’ on the top edge of each board instead of a shadow gap.
Shiplap cladding is available in cedar, larch, and all other dry timber species.

        We can send up to three cladding samples to show characteristics and grade of the wood. We cannot supply specific cladding profiles.

        Please be aware that samples are only intended to give an approximate indication of how the cladding will look when delivered. All timber cladding will include natural variations in colour and quality.
