3) How much British Western Red Cedar Tongue and Groove Cladding do you need?
How to measure for cladding
To get a price, you can type in how many square metres of cladding you need. It's very easy to work out.
We're going to work out the total area of one side of a building, then subtract the windows and doors, then add 10% extra for wastage.
1) For each wall that you’re cladding, measure the full width and the height in metres to work out the total area.
In this (expertly designed) example, the frontage is 9 metres wide and 4.7 metres high. 9 x 4.7 gives a total 42.3 square metres.
Total area of frontage = 9 * 4.7 = 42.3 square metres
2) Work out the area of the doors and windows
In this house front there are four windows and a door. Measure the width and height of each window and door, then add the areas together:
- Window 1: 1.9 x 1.2m = 2.28 square metres
- Window 2: 1.2 x 1.2m = 1.44 square metres
- Window 3: 1.2 x 1.2m = 1.44 square metres
- Window 4: 1.9 x 1.2m = 2.28 square metres
- Door: 1.0m x 2.0m = 2.00 square metres
Total area of windows and doors = 9.44 square metres
3) Subtract the area of the doors and windows from the total area of the wall.
We now have our total area (42.3 square metres) and the total area of the doors and the windows (9.44 square metres). Because we don't want cladding to cover the windows and door, we take the door and window area away from the total area.
Total area to clad = 42.3 – 9.44 = 32.86 square metres to clad
4) Add at least 10% spare for wastage
We recommend ordering at LEAST 10% more cladding than you've measured for to account for the required cutting and shaping.
32.86 square metres + 10% = 36.146 square metres. In this case, we'd round it up to 37 square metres.
Total to order = 37 square metres
Do the same for any other sides of the building, add them together and you'll have your grand total.

Why are the 'per m2' and 'per m' prices approximate?
Your total price is accurately calculated from a cubic metre rate based on the actual total volume of timber in your cladding, rather than from a stored square metre or running metre rate.
In order to show the price per square metre and the price per metre, we divide the total cost by the number of square metres and linear metres respectively. Due to rounding, this may mean that the square metre or linear metre price may be out by a few pence if you manually multiply it be the number of square or linear metres. The total price shown is accurate and we show the square metre and linear metre prices for comparison.

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.
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.
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
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
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. If you are fixing your cladding horizontally, your battens need to be placed vertically, at around every 600mm (60cm), and vice versa.
Fixing
** 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 or nail head when you fit the board to the batten. Look to leave a 3mm gap between the boards, rather than butting them up tight like flooring, 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.
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.
What do our customers say?
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
Delivery times
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.
Delivery day
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.
Delivery times
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.
Offloading
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.
The timbers shown are planed all round samples and are not profiled.
