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.
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.
Treating Timber Cladding
All of our timber cladding is provided untreated.
For best results, cladding should be treated before it is installed to ensure application of the treatment on all sides and ends of the boards.
We recommend Wood Finishes Direct for all of your treatments. We have found them to be well priced and their telephone support and advice is second to none. We highly recommend giving them a call.
The following information is from Wood Finishes Direct in relation to treating timber cladding.
When it comes to treating your timber cladding, there are three areas of protection to consider.
- Sealing against moisture movement - Sealants are used to help prevent moisture entering the wood causing it to expand. Kiln dried timber like European Oak will definitely need to be sealed, and for other timbers it is highly recommended.
- Wood Preserver - Helps to prevent rot and protects the wood from insect infestation and mould.
- UV Protection - The ultraviolet rays of the sun slowly bleach external timbers. UV protection oil helps to keep the natural colour of your timber for longer and prevent it from turning silvery grey so quickly. Some people like their timber to weather and prefer the silvery grey look so it’s completely down to you.
The following links will take you straight to the products on Wood Finishes Direct's website:
Product to Seal and Preserve
To address Sealing and Preserving, they recommend applying one or two coats of "Wood Preserver Basecoat - Barrettine Premier Universal Preserver" before installation to seal against moisture movement and protect it from mould and insects.
Product to Protect from UV Rays
Then to optionally delay weathering, two coats of OSMO UV Protection Oil. There are different colours of OSMO UV Protection Oil available, with names like 'Cedar' and 'Oak', but these colours are to make other timber look like the stated species. We recommend the 420 clear version which interferes the least with the natural colour of your timber.

- Mark Hotchkiss
We have used you before. Very happy with service and ease of ordering.
- Gerald Mummery
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.

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.
How do I receive a delivery?
Our deliveries are carried out by a third party haulage company. Because many of our customers have forklifts on-site, the standard delivery trucks often do not have cranes (or hi-abs) on them.
