All these profiles can be fitted vertically or horizontally apart from IWC5 which is only suitable for vertical fitting. Where necessary we can machine to custom profiles for bulk orders, however we wold require the drawings before we can quote and proceed.
Our Imported, Canadian Western Red Cedar tongue and groove cladding is supplied in "Clear and Better No.2" grade which is one of the highest grades of imported cedar available. The timber is almost knot free giving you a nice clean finish to your cladding and the colour of the cedar is a quite remarkable range of dark reddish-brown to pale pinks and oranges. You can see the range of colours in some of the pictures below.
Imported Western Red Cedar is one of the most resilient when it comes to moisture movement, however we would still recommend sealing it for ultimate stability. Like all timbers, Cedar will turn silver-grey with exposure to sunlight within a few years. If you would like to protect the colour then you can UV protect the timber to prevent it from turning silvery grey. See our "Treatment Guidance" section above.
Our western red cedar tongue and groove cladding is supplied in random lengths between 2 and 4 metres to match the area you want to cover. We can supply exact lengths where required but please check with us before ordering to make sure we can supply those lengths. You can call us on 01889 279 018 or you can talk to us on our online chat. If we confirm that we can provide the lengths please type the lengths you need into the “Special Instructions” box on the shopping basket page after checking with us we can provide them.
If you want to use secret nailing on your cladding then you will need to choose our IWC3 profile.
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:
Imported Canadian Western Red Cedar vs Home-grown British Western Red Cedar
This imported Canadian Cedar has a lot fewer knots than the British Cedar, and also a wide range of warm colours, from reds, oranges and browns to creams. Click here for British Cedar Tongue and Groove Cladding.
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.
