Pine
Pine or Redwood (Pinus Silvestris)
The sapwood and heartwood are yellowish to white-red color. Under circumstances it withstands weather conditions and it is sickly to insects and fungi 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.
True density at 15% humidity: 0.47 g/cm3
The contraction rate % in 1% change in moisture content in the direction of the heartwood is from 0.12 to 0.19% and in the direction of the annual growth rings is from 0.24 to 0.33%.
The pines are harder and heavier than the firs.
