British Western Red Cedar Shiplap Cladding
Our Shiplap cladding profiles are only suitable for horizontal fitting. British Western Red Cedar shiplap cladding is available in two profiles:
- IWC6 - 19mm x 145mm overall, with a 135mm face - For horizontal fitting
- 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.
You can treat your shiplap cladding with a UV protection oil this will stop the timber from weathering and keep its colour for longer. You are better off treating your cladding before you use it so that you can an even coating on the boards, as discussed in the "Treatment Guidance" section.
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.
Be sure to read through our treatment information by clicking on "Treatment Guidance" above. It talks about sealing, preserving and protecting the timber from the sun's UV rays. Here are quick links to the products we recommend:
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.
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
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.
Treating Timber Cladding
All of our timber cladding is provided untreated.
For best results, cladding should be treated before it is installed to ensure application of the treatment on all sides and ends of the boards.
We recommend Wood Finishes Direct for all of your treatments. We have found them to be well priced and their telephone support and advice is second to none. We highly recommend giving them a call.
The following information is from Wood Finishes Direct in relation to treating timber cladding.
When it comes to treating your timber cladding, there are three areas of protection to consider.
- Sealing against moisture movement - Sealants are used to help prevent moisture entering the wood causing it to expand. Kiln dried timber like European Oak will definitely need to be sealed, and for other timbers it is highly recommended.
- Wood Preserver - Helps to prevent rot and protects the wood from insect infestation and mould.
- UV Protection - The ultraviolet rays of the sun slowly bleach external timbers. UV protection oil helps to keep the natural colour of your timber for longer and prevent it from turning silvery grey so quickly. Some people like their timber to weather and prefer the silvery grey look so it’s completely down to you.
The following links will take you straight to the products on Wood Finishes Direct's website:
Product to Seal and Preserve
To address Sealing and Preserving, they recommend applying one or two coats of "Wood Preserver Basecoat - Barrettine Premier Universal Preserver" before installation to seal against moisture movement and protect it from mould and insects.
Product to Protect from UV Rays
Then to optionally delay weathering, two coats of OSMO UV Protection Oil. There are different colours of OSMO UV Protection Oil available, with names like 'Cedar' and 'Oak', but these colours are to make other timber look like the stated species. We recommend the 420 clear version which interferes the least with the natural colour of your timber.
