British Douglas Fir Rainshield Cladding is a pale browney-red colour containing attractive, sound knots.
1) We offer Rainshield Cladding in the following profile
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.

2) We offer British Douglas Fir in the following grade:
Fresh Sawn Merchantable Grade British Douglas Fir
This grade has quite a large grain pattern, is generally a pale reddish-brown colour and is quite knotty compared to the imported Douglas Fir.
3) How much British Douglas Fir Rainshield 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.
If you have any questions, please feel free to give us a call.

Some popular alternatives
British Douglas Fir Rainshield Cladding
We offer a standard British Douglas Fir Rainscreen Cladding which is profile IWC8. IWC8 can only be fitted horizontally and is fitted with around a 12mm gap (click on 'more information' next to the profile above for a diagram).
Home grown Douglas Fir is one of the most versatile British softwoods you can buy as it is useful for external purposes like cladding, and when purchased as beams can also be used for constructional purposes. Our British Douglas Fir cladding is graded as 'Fresh Sawn Merchantable', which is quite knotty when compared to its imported counterpart.
British Douglas Fir naturally varies in colour and can be anything from a pale red to a light orange. The variation of the timber is what makes it so appealing for use because it provides you with a unique product.
We are selling more and more British Douglas Fir as customers look towards British Timbers over foreign alternatives. We are proud to support British Forests which are well managed and help to gear the supply of timber towards making it a reliable resource.
Usually, we supply British Douglas Fir rainscreen cladding in random lengths of 3m and longer. If you have any requirements for exact lengths then please give us a call on 01889 279 018 or talk to us on the online chat so that we can discuss and confirm the availability of your requirements. If we can supply the lengths you need please enter them into the “Special Instructions” box on the shopping basket page.
Treatments
Most people leave their timber to go the traditional silver-grey in the sun. We recommend talking to www.wood-finishes-direct.com if you would like to treat your timber. If you do decide to treat your timber, it needs to be treated all the way round including the ends to prevent moisture getting in at all.
Fitting Guidance
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.
Breathable Membrane
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).
Fixing
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.
