Kiln dried 'Select Tight Knot' (STK) grade Western Red Cedar cladding features sound, tight (intergrown) knots that will not fall out over time. This tongue & groove V - joint cladding is an excellent choice when clear grade is not necessary or a more rustic appearance is required. This product has interesting grain patterns combined with a palette of warm, mellow tones ranging from light amber to deep honey brown. The knots and other natural features define the visual character of this grade.
This cladding product is reversible being planed on one face and fine sawn on the other. Both faces have the v-joint so you can install with either face exposed. The sawn face adds an appealing texture to the finished project.
The STK grade allows burls and naturally occurring markings which are of fairly uniform distribution and add to the character of the product. Sound, live, small to medium tight knots (approximately the size of a 10p piece) are permitted every 150 - 200mm.
Like clear grades, there are many different 'sub-grades' of knotty Western Red Cedar, with various quality levels. Our 'Select Tight Knot' grade is the highest of those 'sub-grades', ofering what we consider to be the best quality at the most reasonable price.
This is a well manufactured and consistent cladding product that represents excellent value for money.

Installation
Western Red Cedar cladding up to 140mm should be fixed with one nail per bearer. For cladding over 140mm fix with two nails per bearer. Tongue & Groove and Microline Channel profiles can be blind nailed; all other profiles should be face nailed.
Finish coatings
It is recommended that finish is applied to all surfaces, including ends, before installation. The type of coating will be determined by the final finish and look selected. Click here for our range of recommended finishes. Alternatively, Silva Timber offer prefinished cladding in either solid colour or translucent stains. The finish protects the wood from moisture absorption and UV degradation. It helps prevents staining caused by mildew and extractives and will increase the service life of timber.
Fasteners
For best results use stainless steel annular ring shank nails. These have thin shanks and blunt points to reduce splitting. Nails should be driven with care into the framing members. Hand nailing is recommended as heavy nailing by pneumatic nail guns can cause wood distortion and splitting.
Batten Spacing
Western Red Cedar Cladding performs best when installed proper on a suitable frame. Cedar cladding should be securely nailed to battens, framing members, or to blocking between framing members. A 600mm spacing between battens is recommended. For more detailed installation information view the Cladding Installation Guide below.

Western Red Cedar Cladding
Western Red Cedar is the ultimate green building material. It is legally, responsibly and sustainably harvested in the publicly managed forests of British Columbia, Canada. Less than 1% of standing timber is harvested each year.
For each tree harvested, three are replanted to ensure the forests will exist in perpetuity. Western Red Cedar has a low impact on the environment throughout its life cycle. It requires significantly less energy to produce than man-made alternatives and is bio-degradable.
