Douglas fir is a straight grained and resilient timber with high strength to weight ratio. It is easily worked with machine or hand tools and possesses excellent nail holding, gluing and staining properties. Seasoning presents no difficulties under controlled conditions and the timber dries easily with negligible checking or distortion. Douglas fir is a premium building product specified by leading architects, engineers and builders for a wide range of construction projects.

How is timber different from other wood?

Timber is just another name for wood, In practice wood in its rough form is usually refered to as timber, tree trunks unprocessed are probably timber in it's purest form. In a house unfinished wood ( generally found in the roof and beneath the floor) is referred to as timber e.g. roof timbers or floor timbers/joists. Timber which has been planed (smoothed) and finished off e.g. skirting boards and window sills are referred to as 'joinery' grade or finished, they are still however timber and the difference is a discriptive reference rather than a physical difference.
