British Douglas Fir Waney Edge Cladding

Our IWC12 profile is the only British Douglas Fir Waney Edge cladding we supply. Waney edge gives a traditional look to your project and no two boards are the same which can make it more appealing than the modern machined cladding profiles.

British Douglas Fir varies a lot in colour from a pale red to a light orange and contains some small knots.

The fresh sawn merchantable British Douglas Fir we supply is great for external use. As one of our more durable softwoods, Douglas Fir is ideal for external use which is a credit to its strength, durability and versatility.

We are proud to supply high quality British timbers from renewable sources. These timbers are competitively priced and are ideal for your cladding. They are durable enough to withstand test of time and are easy to maintain.

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

These are only basic guidelines on how to fit your waney edge cladding, please speak to a professional for advice and help before fitting your cladding because each individual situation is different.

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 waney edge cladding, which is fitted horizontally, your battens need to be placed vertically, at around every 600mm (60cm).

Fixing

** 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.

For fixing the cladding to the battens we recommend that you pre-drill any holes to help avoid splitting the timber. Start by fitting the boards at the bottom of the structure you are cladding and work your way up. Use extra battens underneath the bottom of the bottom board to hold it away from the building. We work out the number of boards you need off a 25% overlap, so if you increase the overlap size you will need to order more boards. It’s important to make sure that the waney edge is at the bottom and the square edge is at the top.

Because the waney edge gives varying widths down the length of the board, you may need to overlap more than 25% in some places to ensure full coverage if you encounter a particularly thin part of a board. It's therefore advisable to order slightly more than you need in case you need to overlap any boards greater than 25%.

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.
