Our black Thermowood is an excellent quality product which is provided ready to fit and is maintenance free for 10 years. 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).
For accessories we recommend using a softwood like British Larch and then painting them black yourself. The treatment used on our timber is Tikkurila Ultra Pro topcoat (colour code: Black 0202), which can be found online.

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.

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.
