Add value to your property with the sleek aesthetics and durability of our premium North West American Douglas Fir cladding. Known for its flowing grain textures and low knot content, Douglas Fir is a premium choice and is a cost effective alternative to western red cedar.

Why Choose clear Douglas Fir?
Opting for our clear Douglas Fir cladding means choosing a cost effective material that combines sleek aesthetics, practical performance, and eco-friendly sourcing.

Appearance
Douglas Fir’s consistent creamy brown hue, with subtle reddish undertones, creates a clean, modern aesthetic. Its mixture of open grain and tight grain patterns provide a sophisticated appearance that complements both traditional and contemporary designs.

Strength & Longevity
Naturally resistant to decay, insects, and rot, Douglas Fir offers reliable durability with minimal maintenance. Coating after installation is essential refer to our install guide for correct coating types. After an initial coating has been applied boards can weather naturally without any further preservatives needing to be applied, making for a low maintenance and hard wearing solution.

Ease of Use & Adaptability
Douglas fir is supplied ready to be fitted with no seasoning time required, it is advised that screws are used to secure the cladding. Overall Douglas fir is an easy species to work with and does not blunt tools. Read our how to install guidelines for comprehensive assistance.

Sustainable
Grown in the Pacific Northwest & British Columbia, in regulated and responsibly managed forests, our Douglas Fir is acquired from FSC & PEFC certified sources. By choosing Douglas Fir, you’re supporting eco-friendly practices.

Let the beauty and durability of Clear Douglas Fir transform your next project with timeless style and exceptional performance.

Wastage Allowance:

• We advise over ordering by 10%, our Douglas fir is quality checked and graded, no 2 clr & btr 15% no 4 clr & btr grade, moisture 18% <.
• No more than 10% of the boards may contain workable naturally occurring defects such as minor surface splits, end splits, and even occasional dead knot holes, but in no more than one per length and in no more than 10% of timber received.

Fixing Types:

All screws, nails, bolts and metallic accessories that come into contact with this product must be corrosion resistant. We recommend:

• Stainless steel

If fixings other than stainless steel are used there is risk of permanent spotting and corrosion stains appearing on the surface. This is due to naturally occurring acidic oils.

Should I use screws or nails for fixing?

• Douglas fir cladding must be secured with screws, screws should sit flush with the surface and not be countersunk, to avoid splits and screw head pull through.
• Douglas Fir is a moderate movement class species as such nails are not recommended.

What size Screws or nails do I need?

• Screws should be a minimum diameter of 3.5mm – pre drill pilot holes 2/3rds of shank diameter to minimize risk of splitting.
• Screw length should be depth of cladding + 25mm or longer

Installing Douglas Fir cladding:

• Our Douglas Fir is supplied dried to a moisture content of 18% or lower, meaning no drying is required prior to installation.
•  It is not recommended to use Douglas fir in saunas, or in wet rooms.
• If being used internally or in boat building we advise further acclimatizing your douglas fir so the moisture content is below 12% Due to its moderate movement class and vulnerability to fungus growth. See maintenance for how to remove and prevent fungal growth.
• Fixing through the face is most secure.
• If board is below 100mm in width insert one centrally placed fixing at every batten.
• If the board width ranges from 100mm to 200mm wide, insert two fixings where the board crosses a batten, positioning the fixings approximately 25mm to 50mm from the board edges.
• Cladding profiles with hidden nail recesses exceeding 100mm in width, should have one fixing inserted into the face spaced approx. 25 – 50mm from the groove and another fixing inserted at an angle into the hidden fixing recess next to the tongue.
• It is not recommended to completely hide the fixings. Instead, ensure your cladding is securely and properly fitted by following this guidance.
• Battens external cladding is fitted to should be treated to protect your structure from moisture.
• Douglas Fir should be secured to battens, battens can be drilled secure to a brick wall using 6mm masonry drill bit and matching screw plugs. Battens can also be screwed using pilot holes into plywood sheets.
• Do not secure Douglas Fir cladding directly to plywood or sheet materials.
• Exposed end grain of boards should be protected with either trims, metal capping or end grain sealant.
• Optional, leave a 175mm gap between the ground and the cladding to prevent the bottoms of the boards from being exposed to ground level moisture, dust and general splatter.
• For horizontally installed cladding battens should be vertically installed.
• For vertically installed cladding battens should be horizontally installed.
• Fixing centres should be a maximum of 450mm apart, Douglas Fir is a species with moderate movement characteristics.
• Batten material should have the same service live as the cladding being chosen, we advise battens used are graded and are pressure treated.
• Minimum batten or lath dimensions should be 50 x 38mm or 50 x 25mm if being counter battened.
• Douglas fir L shaped trims are intended for use on external and internal corners, as well as door and window surrounds, L shaped trims are also used to achieve straight horizontal and vertical lines where minute differences in cut cladding length would be otherwise noticeable.
• In the absence of Douglas fir L shaped trims it is also possible to miter joint two pieces of planed square edge timber together, PSE can be created with an on site table saw, cutting edges on a 45° angle, edge glueing and pinning secure.  
• Do not apply oils, stains, preservatives or paints If your Doug fir is wet or moist, wait until suitably dry. To prevent evaporating internal moisture forcing any coating back to the surface, creating undesired splotches.
• If staggering runs together, ensure they are jointed on battens and also edge glued together to prevent separation and end grain water splotching.

 

Cavities:

• Cavity ventilation barrier of 10mm or more is required to prevent long term moisture build up. Fixing your douglas fir cladding to battens as per above guidance will achieve this. 
• Metal vermin mesh should be fitted at all cavity entrances.
• Optional; breather membrane to be fitted to ply / brick wall battens are secured to, for added moisture protection, (is essential in saunas.)

• Our Commitment: We value lasting customer relationships, which is why we handle all issues promptly and professionally. Your feedback helps us refine our products and services for future customers.

• Applying preservative to externally installed Douglas fir cladding is essential.
• To enhance the natural appearance and to delay the silvering process we advise using a quality translucent UV protection oil such as Owatrol Textrol Hes Clear or for a more cost effective oil use Osmo 420 Clear. These products will slow the weathering / silvering process. Re apply every 2 – 3 years to maintain enhanced natural appearance indefinitely.
• If your species is vulnerable to fungal attack we advise mixing Owatrol VC175 Mould Killer a powerful internal and external anti fungal additive mixable with any oil, varnish lacquer, wood stain or paint, simply mix with your preferred coating for lasting protection. Note: Douglas fir is vulnerable to fungal attack.
• Once your cladding has eventually silvered you may like the silver colour as many customers do, some customers achieve this faster by applying weathered aged wood accelerator for a unique and sort after natural worn aesthetic.
• If you wish to stain, ensure stains offer protection against fungus or can be subsequently coated with a transparent anti fungal coat such as Osmo 420 Clear.  
• If you want to revive your Douglas fir cladding once silvered off there are numerous solutions that will bring your timber back. Depending on how weathered your wood is you may be able to apply wood stain straight onto it, try sampling a small section to see.
• If your wood is heavily weathered, we advise using a power washer after scrubbing the wood with a mixture of water and bleach. Though labor-intensive, this process is cost-effective. Ensure you wear appropriate personal protective equipment. This method is also effective for removing algae, mildew, and fungus. After cleaning, apply protective oils, lacquer, and stains for long-lasting protection and satisfaction with your wood. Do not power wash softwoods with a finished depth of less than 18mm. Avoid positioning the water jet close enough to damage the timber.

• Douglas fir must not get wet or damp whilst in storage, keep your douglas fir dry to prevent fungus growing on it. (To remove fungus see how to maintain section).
• Do not apply oils, stains or preservatives if there are moisture splotches visible on the surface, allow for these to clear before coating.
• Please contact us before delivery to ensure you are prepared. If anything is not right, submit a complaint immediately, and we will be happy to assist.
• Its advised to store your timber either indoors, or outside under ventilated and weighed down tarpaulin sheets and or in a shaded area where the elements cannot reach your wood.
• There is no need to sticker your timber if it is received suitably dry for intended use, it can be stored stacked neatly under cover until you are ready to use it, except for applications where further drying is needed, ie internal use, boat building or installing douglas fir floor boards.
• If your application requires further seasoning purchase a wood moisture meter, douglas fir should be thoroughly dried after 1 month.
• If you decide to sticker your order, the sticks for drying on site must be clean and ideally planed to minimize marks. Any faint marks caused by stickering will fade away over time.
• Timber should be stored raised above ground.
