Western Red Cedar Rainshield Cladding
Our IWC8 profile in Western Red Cedar Rainscreen Cladding gives a super-clean, modern look. IWC8 is designed to be fitted horizontally with around a 12mm gap between the front faces of the boards (click on 'more information' next to the profile above for a diagram).
The clear and better grade that our western red cedar is supplied in is one of the highest quality timbers available. It has minimal knot content which means that you get the full impact of the timber's vibrant colour.
Western Red Cedar is naturally highly durability and resistance to warping through moisture movement. Even so, we'd still advise treating it to be on the safe side. The timber will start to turn silvery grey over a period of time, dependant on how much exposure to sunlight it receives. Using an OSMO UV protection oil will delay the onset of silvering if applied annually.
Usually we supply Western Red Cedar Rainscreen cladding in random lengths of over 2m. If you need exact lengths then please contact us, by calling 01889 279 018 or by talking to us on the online chat, before ordering so that we can confirm that we can provide those lengths.
If we confirm that we can provide the lengths you would like, when you go to place your order, type in your requirements in the “Special Instructions” box on the shopping basket page before you got through to checkout.
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 rainshield cladding and we recommend that you consult an expert fitter to advise on your actual scenario.
Please note: One of the edges of our rainscreen profile has a steeper angle than the other. The profile is designed to be fitted with the steepest angle at the top, so the gap between the boards is widest at the front exposed side, and smallest at the back.
Be sure to read our treatment guidance as treatment needs to be applied prior to fixing your cladding.
Rainshield cladding should be fitted on top of a breathable membrane, because it is designed to be fixed with gaps around it. 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. For rainshield cladding, which is fitted horizontally, your battens need to be placed vertically, at around every 600mm (60cm).
When fitting your timber to the battens we recommend pre-drilling the holes to avoid splitting the wood and then hold the board with screws. Rainshield cladding boards are designed to sit on top of each other and we recommend leaving a 12mm gap in between them on the front face.
Unlike other profiles of cladding, many people line up the joins on each row of cladding to create bold lines for a modern look.
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.

How do I receive a delivery?
Our deliveries are carried out by a third party haulage company. Because many of our customers have forklifts on-site, the standard delivery trucks often do not have cranes (or hi-abs) on them.
