Fir
Fir or white wood (Picea Abies)
General characteristics: The sapwood and heartwood have white to white-grey color. It is characterized by moderate resistance to weather conditions, but it is not resistant to fungi and insects infestation.
Physical Properties: It is of soft to medium hardness, moderately lightweight elastic and solid. It has good stability, it shrinks a little, is good at drying and easy to process. The cross section gives generally oval knots. When processing, it releases a very unpleasant smell.
True density at 15% humidity: 0.50 g/cm3
The contraction rate % in 1% change in moisture content in the direction of the heartwood is from 0.10 to 0.15 % while in the direction of the annual growth rings is from 0.28 to 0.33%.
