Canadian Hemlock
Applications:
In doors, windows, staircases, louvered cabinets, mouldings, spindles and paneling, Pacific Coast Hemlock has already achieved an international reputation for excellence in form and function.The overall uniformity of coloring from heartwood to sapwood, from light honey to a rich golden tan, and the wood's excellent gluing properties make it ideally suited to finger jointing, edge veneering and laminating. Where a uniform color is desired, whether used extensively or in small decorative elements, Pacific Coast Hemlock complements virtually any architectural style or design theme.
Few woods accept finishes so well. The wood's close texture and freedom from pitch eliminate "bleeding" through the surface finish; and the grain pattern is sufficiently unobtrusive to accept a wide range of solid, semitransparent or clear finishes smoothly and evenly in either paint or stain. This multi-finish versatility makes Pacific Coast Hemlock excellent for matching existing millwork. The wood is equally amenable to preservative or fire-retardant treatments when required. It's ability to accept preservatives make it a very popular choice for outdoor decking and fencing
Characteristics Of Hemlock
- Density(oven-dry): 0.42 gm/cc
- Specific Gravity (oven dry): 0.44
- Durability: Good service in construction, although it has little resistance to decay.
- Finishing: Somewhat resistant to conventional preservative treatment. It can be pressure treated but is more effectively treated by a water diffusion process.
- Flame spread rating: 73(class II or B)
- Smoke developed classification: 80K value(12% mc): 0.89 BTU in.per square ft.h degrees F
- Stability: It has moderately large shrinkage, about the same as Douglas-fir.
- Workability: Easy to work in all hand and machine operations and has little dulling effect on cutting edges.
- Density (12% mc) 480 kg/cubic metre (30 lb/cubic foot)
- Strength (12% mc)
- Compression parallel to grain 46.70 MPa
- Tension perpendicular to grain 2.93 MPa
- Modulus of rupture 81.10 MPa
