3) How much British Larch Shiplap 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.

Example Pricing for British Larch Shiplap Cladding
Priced from £28.20 ex. VAT (£33.84 inc. VAT) per square metre (Profile: IWC6 Ship-lap Cladding - Grade: Fresh Sawn Merchantable Grade - 1m 2)
British Larch Shiplap Cladding
Our British Larch Shiplap cladding comes in two profiles for you to choose from which are:
- IWC6 - 19mm x 145mm overall, with a 135mm face - For horizontal fitting
- IWC7 - 19mm x 145mm overall, with a 128mm face - For horizontal fitting
The main difference between the two profiles is the face width you get: IWC6 has a 135mm Face and IWC7 has a 128mm face. Both profiles are only suitable for horizontal fitting.
Although it is fresh sawn, British Larch wood cladding, like so many of our other homegrown timbers is stable enough to be machined into profile. The fresh sawn merchantable grade larch we supply is ideal for external use.
British Larch is variable and colour and can be anything from a pale reddish-brown to a brick red. We recommend treating all external timbers to seal them from moisture movement. All timbers will eventually go silver grey due to the sun's UV rays, but you can preserve the colour of your timber by treating it with a UV protection oil which will protect it from sunlight.
The timber also contains knots which adds character to the wood and makes it look like a more traditional material. We source British Larch from fully managed forests where their aim is not only supply great wood but also make the supply sustainable.
Usually the board lengths of our British Larch Shiplap Cladding are randomly 3m and longer when supplied. Where necessary we can try and provide exact lengths to your requirements, if you do have any special length requirements please call us on 01889 597281 or talk to us on the online chat to confirm we can supply them. If we can, all you need to do is enter your lengths in the “Special Instructions” box on the shopping basket page.
Treatments
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:
Fitting Guidance
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
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. 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.
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.

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.
