Western Red Cedar Tongue & Groove V- Joint (known as TGV) profiled boards can be used in the creation of horizontal, vertical or even diagonal solid board fences. They are typically utilised in contemporary garden design and commercial applications to achieve an attractive high end appearance. The fact that the boards interlock means that this type of fence can provide total privacy.

Silva offers this product in one ‘knotty’ and two ‘clear’ grades of Western Red Cedar – ‘clear’ being the term to describe timber that is largely free of knots and other characteristics. No. 2 Clear & Better is the higher of the two clear grades and therefore has the fewest imperfections. TGV boards produced from Silva’s Select No. 4 Clear & Better contain slightly more knots and other characteristics, but overall will offer a similar ‘clear’ appearance to No. 2 Clear & Better at a lower price. The most economical of these grades is known as Select Tight Knot – a well manufactured product characterised by live knots that are infused into the surrounding wood fibre.

Grading Rules Explained

Build a statement fence from Tongue & Groove Western Red Cedar

The Tongue & Groove V-Joint profile interlocks with adjacent boards to create subtle shadow lines where the boards meet.The clean flat surface and straight lines combine to create a modern look that will suit any environment. Clear grade Western Red Cedar will lend the project a clean contemporary feel and knotty grade a slightly more rustic feel. All three products will provide a level of quality that cannot be achieved with other materials.


The raw material used to produce Silva’s clear TGV boards is fine grained coastal grown Western Red Cedar that has been kiln dried at source to a moisture content of 12 -15% (Select Tight Knot grade is kiln dried to a slightly higher moisture content). This is important for a number of reasons (see document for further information) but the main advantages are that it doesn’t need acclimatisation on site prior to installation and it can be finished immediately so it is protected from the outset. Green or inconsistently air dried wood will shrink after installation causing gaps to widen and may initially be too wet to accept a finish.

Finishing & Protection

It is recommended that a finish is applied to all surfaces, including ends, before installation. The type of coating will be determined by the final finish and appearance desired.

Why Pre-finish?

  • Enhances the natural beauty of wood
  • Ensures a consistent finish
  • Applied in factory conditions
  • Long lasting protection against weathering
  • Simple maintenance routine
  • Reduces onsite labour costs

Easy to apply and maintain, Sansin Enviro-stains deliver outstanding performance. Sansin's range of wood protection products are available in 80 colour tones

What is weathering?

There is a risk involved when leaving wood exposed to the elements. During the weathering process wood can appear unsightly as the material can blacken due to moisture getting into the fibres and pulling out tannins and extractives. Finish protects the wood from moisture absorption and UV degradation.

What to expect from timber products

When working with timber it should be expected that although ‘on-grade’, occasional boards may have minor imperfections that will require ‘working’ if you wish to eliminate. Examples include raised grain, small splits, minor handling marks, sticker marks etc – all of which can easily be remedied by trimming, gluing or sanding. In most cases imperfections can be removed with very little effort, and the small amount of off cuts generated as a result will be absorbed in the normal cutting and selection allowance.



Western Red Cedar No. 2 Clear and Better

This particular product is produced from a sawn Western Red Cedar clear grade known as ‘No. 2 Clear and Better’. It is one of two grades - the other being ‘No. 4 Clear’- of sawn clear Western Red Cedar which are classified in accordance with the R-List Export Grading Rule Book published by the Pacific Lumber Export Bureau.

Silva Select No. 2 Clear & Better far exceeds the grading rules set out in the Export R-List Grading & Dressing Rules book. Usually with this grade you should expect some trimming and wastage; however with this product you will find very little. We have repeatedly been told by industrial users that this product is the best they have seen on the UK market.

More about No.2 Clear & Better

Western Red Cedar No.4 Clear

The first thing to highlight about our ‘Silva Select No. 4 Clear’ product is that it far exceeds the grading rules set out for ‘No. 4 Clear’. Usually with this grade you should expect a certain amount of trimming and wastage; however the producer of the sawn lumber has identified a demand for a product that is less expensive than ‘No. 2 Clear & Better’ but yields less wastage than standard ‘No. 4 Clear’.

In our opinion this has been achieved with Silva Select No. 4 Clear. We call it Silva Select because it’s a cut above the standard grade and we are the only company importing this product into the UK. A number of our customers have expressed surprise at the quality, especially after reading the grade description which makes it sound far worse quality than it actually is.

More about No.4 Clear

Select Tight Knot

Select Tight Knot is the highest standard of knotty cladding and trim available. This grade offers a distinctive, high quality knotty appearance.  It has limited imperfections and restricts knots to sound and tight. 

Western Red Cedar boards are available in kiln dried ‘select tight knot’ grade.  Boards are planed on one face and two edges and sawn on one face.

The grade is characterised by knots, grain patterns and other natural features combined with a palette of warm, mellow tones ranging from light amber to deep honey brown.  Sound tight knots are live knots that are grown into the wood and are less likely to fall out than dead knots.

Silva sources its select tight knot grade Western Red Cedar boards from one of North America’s leading primary sawmills, with a reputation throughout the industry for producing superior quality Western Red Cedar products.

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.
