Douglas Fir (Pseudotsuga menziesii)
A great all-rounder, Douglas Fir has remained a firm favourite of the industry. A versatile timber that is used in high quality joinery, internally and externally. Douglas fir is also being used more for external timber cladding. Due to the size of the tree we are also able to offer in extra large section sizes for construction use.
Technical Information
| Wood Type: | Softwood |
|---|---|
| Environmental: | Sourced from well managed forests with either FSC or PEFC Certification. Third party audited by BM Trada, Forest Products Chain of Custody Certification, certificate number BMT-COC-0032 |
| The Tree: | A large tree attaining a height of 45m to 60m and a diameter of 1m to 2m, occasionally much taller and larger. |
| 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 a 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 |
| Drying: | Imported Douglas fir is not a difficult timber to dry on arrival in this country or in Europe, because the moisture content has already been reduced prior to shipment with some selecting out of degraded boards. Drying degrade is generally confined to surface checking, splitting and loosening of knots, and splitting in the vicinity of knots. Accordingly, stock from trees grown in the UK and in Europe when dried from the green state, needs care, particularly because of the generally higher preponderance of knots which are hard, often loose, and which encourage more wavy grain than in imported stock. |
| Strength: | Compared with European redwood, it is some 60 per cent stiffer, 40 per cent harder and more resistant to suddenly applied loads, and 30 per cent stronger in bending and in compression along the grain. |
| Durability: | Moderately durable Slightly durable (Homegrown timber) |
| Treatability: | Extremely difficult Difficult (Sapwood) |
| Moisture Movement: | Small |
| Density: | 530Kg/m³ |
| Texture: | Medium |
