Moderately dense and hardwearing, Douglas fir is known for its strength, durability and longevity; a popular choice for cladding projects


Douglas fir, or British Columbian Fir, is a characterful timber which is a rich red-brown colour, but often features variations of pink, brown and cream depending on the cut of the tree. It includes knots and has a larger grain pattern which, added to the colour variations, makes Douglas fir a popular choice for timber cladding. Left untreated, it will weather to a stunning silver-grey colour.

Douglas fir is available in two grades:

  • Classic; faster growing which results in widely spaced growth rings and a coarser texture with a bold grain and larger, more frequent knots compared to Premium
  • Premium; slower growing trees results in growth rings which are closer together, resulting in a timber with exceptional quality and texture, few and smaller knots.

Always seek advice about treatment and after-care to preserve the aesthetics and style you want for your cladding in the longer-term.
