Not what you're looking for? Head over to our Cedar Cladding page to see all of the Western Red Cedar Products we have to offer.

Our Shiplap cladding profiles are only suitable for horizontal fitting. British Western Red Cedar shiplap cladding is available in two profiles:

• IWC7 - 19mm x 145mm overall, with a 128mm face - For horizontal fitting

There is a rise in demand for British timbers with more and more projects specifying that any timber used is British. We are happy to provide different British timbers and support local sawmills as well as those on the continent and further afield.

The British Cedar that we provide is graded as "Fresh Sawn Merchantable". Home grown Cedar is naturally more knotty than the Canadian Cedar we supply which, depending on your point of view, gives the timber more character and gives a more traditional look to your cladding. The colour is a light reddish-brown and it will weather over time to a silvery grey.

British Western red cedar cladding is supplied in random lengths of 3m and longer. There is a chance that we can supply the exact lengths that you would like if you need us to but we do ask that you check with us before ordering. You can call us on 01889 597281 or talk to us on our online chat. If you have confirmed the lengths with us you can enter your requirements in the “Special Instructions” box on the shopping basket page before checking out.

Treatments

Most people leave their timber to go the traditional silver-grey in the sun. We recommend talking to www.wood-finishes-direct.com if you would like to treat your timber. If you do decide to treat your timber, it needs to be treated all the way round including the ends to prevent moisture getting in at all.

Canadian and British Western Red Cedar

Please see below some pictures of planed all round Western Red Cedar slats. Although they aren't pictures of cladding you will be able to see the colour difference between the Canadian and British Western Red Cedar which will help you to make a choice between the two.

Fitting Guidance

Our fitting guidelines are designed to give you a starting point on how to fit your shiplap cladding and we recommend that you consult an expert fitter to advise on your actual scenario.

Be sure to read our treatment guidance as treatment needs to be applied prior to fixing your cladding

Breathable Membrane

Consult a fitter to determine if your scenario would require the fitting of a breathable membrane between your wall and the cladding. This membrane stops rain getting to the wall, but allows moisture to escape, helping to prevent internal condensation and mould that can come with it.

Treated Softwood Battens

Treated softwood battens (available from our cladding accessories pages) are most commonly used to fix to the wall (or on top of the breathable membrane) to then fix your cladding to. Shiplap cladding is to be fixed horizontally only, so your battens need to be placed vertically, at around every 600mm (60cm).

Fixing the Cladding

** Whether you use nails or screws, it's important that they are stainless steel, or silicone bronze ARS, so that the natural tanins in the timber will not corrode them. Never use iron nails for fixing timber.

The timber is designed to only be fitted horizontally with the start of the running lip across the width of the timber at the top. To stop your wood from splitting it’s best to pre-drill any holes and then hold the boards with the head of the screw.

You can also use nails, preferably ring-shanked for extra grip, and again stainless steel so they don't corrode. For lower-density species like cedar, consider using nails with larger heads so the cladding doesn't pull through.

As already stated, these are just ideas to get you thinking about installation and you should consult a professional installer before fitting your cladding as every scenario is different.

All our claddings are provided untreated. Fresh sawn timber claddings are best left untreated and to go silver grey. There are a wide range of optional treatments available for different species of timber and we recommend talking to the excellent team at www.wood-finishes-direct.com, who know the most up-to-date information on all the newest treatment products.
