second variety of Douglas Fir, Pseudotsuga menziesii var. glauca is commonly
called Rocky Mountain Douglas Fir or Blue Douglas Fir.
Douglas Fir is a softwood widley available throughout Australia. The source of the timber is primarily North America with additional supplies being plantation grown in New Zealand.
The timber is easy to work, although due to the difference in hardness between earlywood and latewood some care is required in planeing and dressing, differential glueing can occur and end spliting may result when nailing.
Douglas Fir is available in a large range of sizes and lengths, commonly up to 7.2m and often longer. It has been regularly used as construction timber in Australia for over 100 years as well as high grade joinery such as windows, doors, mouldings, staircase components and exposed beams.
