Western Hemlock

By ITI Timspec
Website
  • 1. A softwood of the high rainfall areas of the west coast of Canada and extending south into the United States. It is one of the important timber species of western Canada.
  • 2. Heartwood straw to pale brown, sometimes with a pinkish tinge. Sapwood is not easily distinguishable and to 25mm wide. The texture is relatively fine and even grain straight. The growth rings are prominent because of the darker bands of latewood, but less so than those of Douglas Fir and usually non-resinous.
  • 3. Air Dry Density is about 500kg/m3.
  • 4. The green wood has a much higher moisture content than that of Douglas Fir and it is slower and more difficult to dry. The moisture content of green material can vary greatly. Care is needed to avoid surface checking. Shrinkage is about 2.5 % radial, and 5% tangential.
  • 5. Easy to work, except for the small hard knots. Glues satisfactorily. Holds nails well. The relative softness of the earlywood and its possible compression by the planer can lead to ridged material.

Grain texture | Colour | Appearance
Grain is generally straight, with a coarse, uneven texture. Heartwood is light reddish brown. Sapwood may be slightly lighter in colour but usually isn't distinguished from heartwood. Occasionally contains dark streaks caused by bark maggots. The conspicuous growth rings can exhibit interesting grain patterns on flatsawn surfaces.

Overview

Certifications Available
PEFC/40-31-26 Promoting Sustainable Forest Management

Working Qualities
Overall working properties are good, but because of the disparity between the soft earlywood and the hard latewood, sanding can create dips and uneven surfaces. Glues, stains, and finishes well.

Uses
Boxes, pallets, crates, plywood, framing, and other construction purposes.
