British Western Red Cedar Tongue and Groove Cladding
The following five profiles are all available for British Western Red Cedar Tongue and Groove Cladding:
- IWC1 - 19mm x 145mm overall, with a 135mm face - For horizontal or vertical fitting
- IWC2 - 19mm x 95mm overall, with an 88mm face - For horizontal or vertical fitting
- IWC3 - 19mm x 142mm overall, with a 125mm face - For horizontal or vertical fitting
- IWC4 - 19mm x 145mm overall, with a 125mm face - For horizontal or vertical fitting
- IWC5 - 19mm x 145mm overall, with a 125mm face - For vertical fitting only
Most of our T&G profiles are designed to be fitted either horizontally or vertically, only IWC5 is vertical fit only. This makes Tongue and Groove one of our more appealing profiles because you can choose to fit your cladding whichever way you want.
There is a growing trend for home grown timbers and they are becoming more sought after than their foreign counterparts. There are management processes in place within British forests which help the conservation of trees which in the long run will help the supply of timber and the environment.
British Western Red Cedar isn’t as vibrantly coloured as its Canadian counterpart and it contains more knots. The timber is provided in the Fresh Sawn Merchantable grade and even though it is fresh sawn the wood is stable enough to be machined into profile.
When looking to treat your timber you can use a UV protection oil to stop it from weathering to a silvery grey. This will help to keep the colour of the timber for longer. See our "Treatment Guidance" section above.
We usually supply cladding in random lengths of over 3m. We can provide exact lengths however we do ask that you call us on 01889 597281 or talk to us on the online chat before ordering. This is so that we can check the availability of the lengths you need. If we can give you the lengths you need then please enter them into 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.
These fitting guidelines are only a rough idea on how to fix your tongue and groove cladding. We do recommend you employ a professional who has experience fitting tongue and groove cladding.
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. If you are fixing your cladding horizontally, your battens need to be placed vertically, at around every 600mm (60cm), and vice versa.
** 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.
To help stop the wood from splitting we recommend pre-drilling the timber and then holding it with the screw head when you fit the board to the batten. Look to leave a 3mm gap between the boards to account for any moisture movement and make sure that the tongue is facing upwards otherwise moisture will start gathering in the groove of the profile.
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.
You can fit IWC 1,2,3 and 4 vertically or horizontally depending on the look you want from your timber. Whilst technically you can fit IWC5 horizontally, water can sit in the square channel, which is not recommended.
With each new row of cladding you add, it's preferred that you stagger the joins between each board so you don't create a visible seam.
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.
What do our customers say?
Used previously and been very satisfied with service and value.
- Andrew O'Dare
Have used before. Great products and service.
- Jeff Benson
The order process is excellent, this is my second order with you.
- Rob Hill
Just a quick line to say thanks for the swift delivery of the ash I ordered a couple of weeks ago. It is now installed as stair treads/ landing and looks superb. Just one small gripe, the delivery driver didn't call me to say he was on his way which meant I had to rush over; he did help me carry it into the house though.
I think the picture does them justice.
- Stephen Barker, Spalding
Stanbrook & Nicholson Ltd have been buying European Oak from iWood since their inception. In our trade it is often difficult to get both service and product quality from our suppliers. iWood have consistently provided us with an absolute first rate product with service to match. A high proportion of our timber purchased comes as cut to size putting our wastage at nearly zero per cent. This also speeds our process of manufacture.

Some commonly asked questions
Our timber is imported straight from sawmills on the continent. Our usual lead times are therefore 14 to 17 working days.
What are your delivery costs?
We calculate our delivery costs based on how far away you are from us, to get more information on this please check out our shipping costs page HERE.
Our delivery lorries visit different parts of the country on different days, so once your order is ready we will work with you to arrange a delivery day for when one of our lorries is in your area. We will always arrange the delivery day in advance with you.
We deliver weekdays Monday to Friday between the hours of 8am to 5pm. Our delivery vehicles will have multiple jobs on them which can affect the delivery time to you, depending on factors such as traffic and how long it takes to offload the previous jobs. The driver will call you in advance with an estimated time of arrival to make sure you'll be there.
Aside from delivery locations that are priced on application, your delivery will be provided with means of offloading from the truck. This may be by HIAB (lorry with a crane arm), or by supplied manpower. The method will be determined by the haulage company we use based on your location and available options at the time. Please note, both offload options will drop your order to the side of the lorry, they won't be able to carry it around the back of a property, for example.
For areas that are priced on application, by default, we will quote for delivery on a flat-bed lorry that you'll need to arrange to offload yourself. We can quote for offloading on request, but to these areas it's usually prohibitively expensive, and cheaper for you to hire a forklift, or arrange to have enough people on-site to offload.
How do I place an order for cladding?
You can place your order online by working out your price above and adding your items to your shopping basket. You can then check out and your order will be processed securely and a confirmation email sent. Once your order arrives in our depot, we'll give you a call to arrange delivery.
Can I Order Samples?
Yes you can, you can order samples of certain timbers at www.iwood.co.uk/sample-request/.
If the species you need isn't there please give us a call or talk to us on our online chat.
