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.
If you have any questions, please feel free to give us a call.
Example Pricing for Painted Black Thermowood
Priced from £62.77 ex. VAT (£75.32 inc. VAT) per square metre (Profile: IWC15 T&G 141mm (125mm Face) x 20mm - Grade: Thermowood - 1m 2)
Black Thermowood
Our black Thermowood is an excellent quality product which is provided ready to fit and has an expected 10 year maintenance period. This makes it an ideal solution for your project if you don’t want to treat and re-treat the wood yourself.
The wood is dried and all of the moisture is taken out of it, which makes it as stable as possible and means the timber won’t move very much because it can’t dry any further. Thermowood is weather resistant and remains stable in temperatures ranging from -40o to 40o.
The timber itself is a high grade softwood (Scandinavian Pine) which contains sound knots and no resin. The finished product is highly resistant to decay as long as it is used above ground and not in constant direct contact with soil and/or water.
The black topcoat which is applied forms a layer of film over wood and helps to prevent water penetration. This treatment adapts to the climate allowing the wood to breathe.
The timber is provided in a T&G profile which can be fitted either horizontally or vertically. The profile is designed to be secret nailed along a small groove in the wood. The timber can still split under nailing, so pre-drill your holes and then rest the board on the nail/screw head (make sure you use stainless steel).
As we hold the boards in stock we can usually get the timber out to you in 7-10 working days. The boards are usually supplied 4.5m and longer although that is subject to change depending on availability (we don’t offer cross-cutting on these boards).
What do our customers say?
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.

Some commonly asked questions
Delivery times
Our timber is imported straight from sawmills on the continent. Our usual lead times are therefore 7-10 working days, as this product is currently in stock..
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.
