Douglas Fir Feather Edge Cladding
We supply two default Douglas Fir Feather Edge Cladding profiles:
- IWC9 - 200mm wide Feather Edge Douglas Fir Cladding - to be overlapped 25mm giving 175mm face cover
- IWC10 - 150mm wide Feather Edge Douglas Fir Cladding - to be overlapped 25mm giving 125mm face cover
Feather edge is a one of our most popular products for a number of reasons:
- It is the most traditional form of cladding on the market.
- The price is very competitive against the machined forms of cladding.
- You have more control over your cladding because you can choose the amount of overlap you would like.
The clear and Better grade Douglas Fir we supply is virtually knot free and any knots found will be small. This clean timber is light reddish brown in colour and gives a modern feel to one of our more traditional products.
Normally we provide Cladding in random lengths depending on the species, for Douglas Fir those lengths are between 3m and 4.8m. If you need a custom profile or require exact lengths please talk to us on our online chat at the bottom right of your screen or call 01889 279 018 and we will be happy to help. On the shopping basket page there is a “Special Instructions” box where you can enter your exact lengths if you have checked we can supply them beforehand.
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.
Our Feather Edge Cladding is designed to be installed by a professional with previous experience in successfully fitting it. The information here is provided as an overview only and is not a substitute for professional fitting advice.
Be sure to read our treatment guidance as treatment needs to be applied prior to fixing your cladding
Consult a fitter to determine if your scenario would require the fitting of a breathable membrane between your wall and the cladding. 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. Feather Edge Cladding is for horizontal fixing only, so your battens need to be placed vertically, at around every 600mm (60cm).
Fixing the Cladding
** Whether you use nails or screws, it's important that they are stainless steel, or silicone bronze ARS, so that the natural tanins in the timber will not corrode them. Never use iron nails for fixing timber.
There are two common ways to fix feather edge cladding. The first is to nail it, in which case it's best to use two nails across the width of the board (so one vertically above the other), as long as you don't nail through two boards at once with the same nail, so it won't split as it expands or contracts with the seasons.
If you use nails, preferably use ring-shanked for extra grip, and again stainless steel so they don't corrode. For lower-density species like cedar, consider using nails with larger heads so the cladding doesn't pull through.
Secondly, you can pre-drill holes wider than the body of the screws you are using, and hold the boards with the head of the screw. This will allow movement without splitting the boards.
Either way, start at the bottom and use an extra batten to space the bottom of the bottom board away from the building. Work your way up the building. Make sure you have the thinnest part of the board at the top.
Layout of the cladding
With each new row of cladding you add, it's preferred that you stagger the joins between each board so you don't create a visible seam.
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.
