What is American Douglas Fir Timber?

American Douglas Fir Timber is a very popular softwood species due to its strength and versatility. We stock both timber from North America and Europe. It is mainly imported in grade #2 / 3 clears 85 / 15 which results in a small knot-content.

American Douglas Fir is used for joinery exterior and interior, cladding, structural use, flooring, construction and much more. Thicknesses kiln dried are 26mm, 38mm, 51mm, 63mm, 76mm and 102mm. Widths in packs are random 4" - 12", lengths mainly 7' - 16' but can be longer. 


The Timber 

The heartwood is light reddish-brown in colour, usually quite distinct from the lighter coloured sapwood. The abrupt change and contrast in colour between early-wood and late-wood bands, produce a prominent growth ring figure which is a feature of plain-sawn surfaces and of rotary-cut veneer. The wood from trees grown in the UK appears to have less resin than the North American wood, and to some extent is of more rapid growth. The average weight of dried timber from either source is about 530 kg/m3.


Strength and Durability

American Douglas Fir is compared with European Redwood, it is some 60 per cent stiffer, 40 per cent harder and more resistant to suddenly applied to loads, and 30 per cent stronger in bending and in compression along the grain.

American Douglas Fir is moderately durable and is slightly durable (homegrown timber). The heartwood and sapwood are both permeable. It is moderately resistant to decay. 


Physical Properties

American Douglas Fir is extremely difficult to treat, and the sapwood is difficult. It has good overall strength, is very stiff, has low shock resistance and is stable.
