Detailed Species Information

Western Red Cedar

Western Red Cedar (Thuja plicata)

Western red cedar grows at low-to-mid elevations along the Coast and in the wet belt of the Interior, where the climate is cool, mild and moist. It is a large tree, up to 60 metres tall when mature and 2.5 metres in diameter. It is rarely found in pure stands and is often mixed with Douglas-fir, Sitka spruce, black cottonwood and red alder. Western red cedar makes up approximately 8% of British Columbia’s total growing stock, and is one of the most commercially valuable species.

Common Uses

Due to the unique properties of western red cedar, have been developed for a variety of different applications. The main attribute of western red cedar is its excellent durability and dimensional stability, leading to uses such as roof shingles, exterior siding, exterior cladding, decking, weather boarding, greenhouses, portable buildings, bee-hives, poles, posts, fences, ship and boat building, as well as boxes and crates. Red cedar is a popular wood for outdoor furniture and playground equipment.

Western red cedar is an attractive wood that is also used in interior applications. This wood is popular for sashes, doors and windows, ceiling and wall panelling, as well as for millwork. Due to its dimensional stability it is perfectly suited to uses such as sauna panelling, mouldings and window blinds. Red cedar is also a good choice for musical instruments due to its superb acoustic resonance properties.

Working Properties

Western red cedar is a fairly lightweight wood, which is moderately soft and low in strength. It is known for its excellent working properties, and its ability to take a smooth, satiny finish with sharp tools. It is relatively easy to work, with good machining qualities. It planes and shapes well and can be sanded to a smooth finish. The wood glues easily, has moderate nail and screw holding ability, and takes a good finish.

Process Performance Comments
Machining
Planing Moderate to good Recommended planer settings: 20° hook and 20 kmpi (knife marks per inch).
Wood is subject to compression during planing. Must use sharp cutting tools.
Wood is somewhat brittle and splintering is common.
Turning Medium to low
surface quality
Common defects: torn out grain.
Sawing Easy to work with tools Easy to saw because of its low density. Corrosive properties can be damaging to cutting blades.
Boring Good to medium Good boring quality with brad point bits and moderate quality with single twist bits.
Mortising Moderate Better mortising quality is found with a hollow chisel mortise.
Shaping Good shaping quaility Splintering on the end-grain may be an issue.

Recommended: The use of a counter piece for end-grain shaping.

Veneering N/A
Sanding Excellent
Fastening
Screwing Low to moderate Average screw retention: 308 lb.
Lateral Nail Holding N/A
Nail Retention Low to moderate Due to the acidic properties of its extractives this wood tends to accelerate the corrosion of metals, particularly when in contact with unprotected ferrous metal. Hot-dipped galvanized nails are recommended. It is essential that stainless steel, brass, aluminium, copper or metals with a protective coating be used when applying fittings, fixtures or fasteners.
Gluing Easy Bonds very easily with adhesives of a wide range of properties and under a wide range of bonding conditions.
Finishing
Staining Easy Very smooth texture achieved, but sometimes difficult to hide natural texture of wood. Very soft wood that loses some grain design as stain becomes darker. Some wild grain was present in Interior red cedar.
Painting Moderate to good paint holding ability
Lacquering Good Clear coats with little difficulty. A high build clear coat works best for the coastal wood while it was recommended for Interior red cedar to use a clear finish, nitrocellulose/alkyd sealer and finish system.

Performed well in the tape test (i.e. small flakes of the coating were detached along edges and at intersections of cuts) and in the pull-off test
(i.e. average strength of 25 kg/cm2).

Waxing Good Good results are obtained when using light-, medium- or dark-coloured waxes (e.g. Mellow Pine, Chestnut or Jacobean).
Drying
Ease of Drying Moderately easy to difficult The drying of thin boards is generally easy with little degrade occurring. As red cedar tends to hold its moisture at the centre, care is required when drying thicker stock as internal honey-combing and collapse are common defects. Longer drying times are required.
Durability
Natural Decay Resistance Durable Appropriate for outdoor usage.
Treatability Impermeable to
extremely impermeable
Can be improved by incising.

Douglas Fir

Douglas Fir (Pseudotsuga menziesii)

Douglas fir is one of the best known wood species in the world. Douglas-fir is a large tree reaching heights of 85 metres.

Common Uses

Douglas-fir is primarily used for building and construction purposes due to its strength advantages and availability of large dimensions from old-growth trees. It is one of the finest timbers for heavy structural purposes, including laminated arches and roof trusses. Structurally, it is used in the form of lumber, timbers, pilings and plywood.

Douglas-fir is seen as a first class wood for the manufacturing of sashes, doors and windows. The wood is also used to produce a wide variety of products including general millwork, flooring, furniture, cabinets, veneer, vats, ship and boat construction, transmission poles, and marine pilings.

Douglas-fir lumber is dried according to end-use and customer specifications. Kiln drying inhibits natural staining of the wood, improves its strength and stiffness, enhances its appearance, and increases its resistance to decay and attack by insects.

Engelmann Spruce

Engelmann Spruce (Picea engelmannii)

Engelmann spruce occurs at high elevations and interbreeds with white spruce in areas where their ranges overlap, and they are referred to as Interior spruce.

Common Uses
Engelmann pruce wood is highly valued for lumber, plywood and pulp production. As dimension lumber, Engelmann spruce is extremely versatile because of its high strength-to-weight ratio. It is used in building construction (framing, sheathing, roofing, sub-flooring), general millwork, interior finishing, boxes and packing cases. Its dimensional stability and superior gluing properties make it popular in the prefabrication industry. Engelmann spruce is used in the manufacture of modular houses, trusses, and other structural components that specify kiln-dried SPF wood. As a premier pulpwood, the species is used in the manufacture of newsprint and bleached Kraft pulps. It is also used in the manufacture of medium density fiberboard (MDF), paperboard and felt, and it is a major species used in Canadian softwood plywood. Other uses of white spruce include: sounding boards in musical instruments from select materials, food containers (because it is almost colourless and odourless when dried), paddles and oars, cooperage, organ pipes, shelving, and ladder rails.
