Buy Douglas Fir – Beams, Boards & Posts
Douglas fir is the most popular softwood for outdoor use — and with good reason. With its warm, reddish-brown colour and natural durability class 3, Douglas fir combines aesthetics with performance. At Houthandel Jan Sok you will find a complete range of Douglas fir beams, boards, posts, weatherboard cladding and decking in various dimensions and lengths.
Properties of Douglas fir
Douglas fir (Pseudotsuga menziesii) is distinguished by a higher resin content, which makes it naturally more resistant to moisture and mould. Untreated, Douglas fir lasts 10 to 15 years; with a quality oil or stain, considerably longer. Its beautiful, warm colour makes Douglas fir the first choice for verandas, pergolas, fences and façade cladding.

How do I maintain Douglas fir?
To preserve its warm colour, treat Douglas fir annually with a UV-resistant wood oil. Left untreated the timber will naturally weather to a silver-grey, but remains structurally sound. Remove moss and algae with a soft brush and green soap.
