Western Red Cedar is famed for its extraordinary beauty, natural durability, dimensional stability and insulation value. It exudes warmth, thanks to its richly textured, tactile grain and palette of mellow colour tones, which vary from light amber to dark reddish-brown. It also retains its characteristic cedar fragrance and this subtle aroma adds another dimension to its appeal.
Western Red Cedar is renowned for its attractive appearance. It has a pleasing range of natural hues, tight grain patterns and soft textures, which gives the wood an exceptional warmth and beauty.
Western Red Cedar’s naturally occurring compounds called “thujaplicins” act as natural preservatives, making the wood incredibly durable. Properly finished and maintained, cedar will deliver decades of trouble-free service. It has a decay resistance of durability class 2 (durable) according to the EN 113 standard.
Western Red Cedar has excellent dimensional stability because of its low wood density and low shrinkage factor. It absorbs less water than other wood species because the wood contains high levels of extractives which block the absorption sites. As a result, Western Red Cedar shrinks and swells minimally, displaying only small movements with changes in humidity.
The wood of Western Red Cedar is light, weighing 370 to 385 kg/m³ when kiln-dried (12-15% moisture content). Natural variation will occur between individual boards.
Wood generally is an excellent thermal insulator, but Western Red Cedar has a particularly good insulation value because of its low wood density. Woods with low density have the highest thermal insulating value because such woods contain a high proportion of cell cavities. In dry wood, these cavities are filled with air, which is one of the best-known thermal insulators.
Western Red Cedar’s ability to damp vibrations is an important acoustical property that makes it particularly effective for use as interior panelling to help reduce or confine noise. Cedar has a cellular network of minute interlocking pores which convert sound energy into heat by frictional and viscoelastic resistance.
Silva's Western Red Cedar cladding is kiln dried in state-of-the-art kilns. Kiln drying is a far better method of drying wood than air drying, as a far more consistent and accurate moisture level can be achieved resulting in improved dimensional stability, the ability to apply a finish immediately and install with minimal site acclimatisation.
Cowichan Gold is exceptional Western Red Cedar cladding and trim, produced from fine-grained old-growth wood fibre sourced from the coastal regions of British Columbia.
Cowichan Gold, is almost entirely knot-free, all heartwood and all vertical grain, making it the highest quality Western Red Cedar cladding and trim product available anywhere.
Silva Select Western Red Cedar is produced from the highest quality clear vertical grain wood fibre. The raw material is from trees harvested in the coastal regions of British Columbia, that produce fine tight-grained logs.
Specially selected No. 2 Clear & Better Vertical Grain heartwood is pre-graded at the sawmill, sized and graded in the planning facility, dried under strict controls, and then graded once again. The result of this three-step process is the highest standard No. 2 Clear & Better available.
The Cascadia brand from Terminal encompasses superior kiln-dried live-knotted Western Red Cedar cladding and boards.
The combination of specially selected coastal grown wood fibre and Terminal’s fastidious approach to quality and consistency set Cascadia Western Red Cedar cladding and trim apart from the rest.
Numerous reports by wood scientists and experts highlight that wood cladding performs best when supplied factory coated on all six sides. The application of a coating is necessary to protect the wood from the damaging effects of moisture and UV, to help prevent the wood from turning grey and to curb the growth of fungi that produce mould or stains.
Western Red Cedar cladding from Silva can be supplied factory coated, enabling it to be installed at any time of year, regardless of the weather or temperature. When coatings are applied in ‘ideal conditions’ the variables that affect the quality of a site applied finish are eliminated. Weather, temperature and humidity will affect finish quality, and keeping the wood clean, dry and out of direct sunlight prior to application will have a positive effect on the performance of the finish.
