1) We offer Rainshield Cladding in the following profile
Imported Canadian Douglas Fir Rainshield Cladding tends to be an orangey-red colour with fewer knots than the British Douglas Fir.

IWC8 Rainshield 142mm (138 face) x 19mm
IWC8 Rainshield 142mm (138 face) x 19mm
The rainshield profile is a slanted rectangle shape (nearly a parallelogram, technically an obtuse trapezoid with chamfers!). It's designed to be installed horizontally with a slight gap between the boards, giving an extremely modern, uniformed look. People often cut to exact lengths too to give a purposefully regimented, grid-like pattern.

Some popular alternatives
Douglas Fir Rainshield Cladding
Our Douglas Fir rainscreen cladding profile is called IWC8. IWC8 can only be fitted horizontally.
The colour of Douglas Fir is a light reddish brown. The Clear and better grade Douglas Fir we supply is almost knot free which will give your timber a contemporary look. This clean-cut timber is a popular choice and is ideal for external cladding.
You will need to treat your timber in order to seal it. By sealing your Douglas Fir Rainscreen cladding you will prevent water movement in and out of the timber which will help to prevent the boards from expanding and contracting as the moisture content increases and decreases with the seasons.
As with all timbers Douglas Fir is also subject to weathering when in direct contact with sunlight, this means that over time the wood will turn silvery grey. There are treatments which will help to preserve the colour of the timber by protecting it against UV rays.
If you would like a different profile to our IWC8 or need exact lengths (usually supplied in random lengths of 3m and longer) please call us on 01889 279 018 or talk to us on our online chat. For a different profile we would need the drawing and then we can quote separately for it, however if we can supply exact lengths, please enter the lengths into the “Special Instructions” box on the shopping basket page.
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:
Our fitting guidelines are designed to give you a starting point on how to fit your rainshield cladding and we recommend that you consult an expert fitter to advise on your actual scenario.
Please note: One of the edges of our rainscreen profile has a steeper angle than the other. The profile is designed to be fitted with the steepest angle at the top, so the gap between the boards is widest at the front exposed side, and smallest at the back.
Be sure to read our treatment guidance as treatment needs to be applied prior to fixing your cladding.
Rainshield cladding should be fitted on top of a breathable membrane, because it is designed to be fixed with gaps around it. 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. For rainshield cladding, which is fitted horizontally, your battens need to be placed vertically, at around every 600mm (60cm).
When fitting your timber to the battens we recommend pre-drilling the holes to avoid splitting the wood and then hold the board with screws. Rainshield cladding boards are designed to sit on top of each other and we recommend leaving a 12mm gap in between them on the front face.
Unlike other profiles of cladding, many people line up the joins on each row of cladding to create bold lines for a modern look.
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.

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.

Well priced and easy to order.

Some commonly asked questions
How long does the cladding take to deliver?
Because we are sourcing our wood based on demand to ensure the highest quality, delivery may take from 14 to 17 working days once your order has been placed with us.
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.
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.
