Silva’s tongue and groove v-joint cladding is produced from fine-grained, old-growth Western Red Cedar wood fibre, sourced from forests in the coastal regions of British Columbia and is ‘Cowichan Gold.’
It is virtually knot-free, all heartwood, and all vertical grain, making it a high Western Red Cedar cladding.
The tongue and groove v-joint profile is installed horizontally or vertically. A bevel on both edges of the face creates a neat v-shaped shadow line that accentuates the width or height of any façade, providing a sharp contemporary appearance.
- Size: 18x137mm.
- Grade: Clear Heart Vertical Grain.
- Profile: Tongue & Groove connection with a bevelled edge to create a v-shaped shadow line.
- Installation: Vertical or horizontal.
- Surface texture: SAWTEX™ fine sawn finish on the face (for optimal coating performance), smooth finish on the rear.
- Moisture content: Kiln dried at source to 12–15%.
- Colour: Palette of rich, warm wood tones, which vary from light amber to dark reddish-brown.
- Vertical grain (VG): Vertical grain wood has superior properties to flat grain. It has better dimensional stability, better resistance to UV degradation, very low surface cracking and checking, and better finish absorption and retention qualities.
- Durability: When properly finished and maintained, Western Red Cedar will deliver decades of trouble-free service. It has a decay resistance of durability class 2 (durable) according to the EN 113 standard.
- Stability: Western Red Cedar has excellent dimensional stability because of its low wood density and shrinkage factor. Shrinkage and swelling are minimal, displaying only small movements with changes in humidity.
- Density: The wood of Western Red Cedar is light, weighing 330 to 340 kg/m3 when kiln-dried (12-15% moisture content).
- Thermal properties: Wood generally is an excellent thermal insulator, but Western Red Cedar has a particularly good insulation value because of its low wood density. Its coefficient of thermal conductivity (k) is 0.11 W/m °C at 12% moisture content.
- Acoustic properties: Western Red Cedar is particularly effective when used as interior panelling to dampen vibrations and absorb sound.
- Kiln-dried: Cowichan Gold Western Red Cedar is kiln-dried, giving it many advantages. The process improves dimensional stability, permits the immediate application of a coating, and enables installation with minimal site acclimatisation.
- Grading: Cowichan Gold is virtually knot-free, all heartwood, and all vertical grain, making it the highest quality Western Red Cedar cladding available anywhere. Read our Cowichan Gold Grade & Quality Description here.
- Sourcing/certification: Western Red Cedar is sourced from the most sustainably managed forests in the world in British Columbia, Canada, and comes with PEFC certification.
