Canadian Western Red Cedar wood cladding

Canadian Western Red Cedar is the ‘gold standard’ for exterior timber cladding projects in the UK. The reason is simple – it is the perfect material for the job because of its amazing look, ease of working, natural durability and stability.

Canadian Western Red Cedar is much slower grown than British Western Red Cedar resulting in a denser, darker wood with a more varied colour palette. It also renowned for offering a cladding that is completely clear and free of imperfections – i.e. zero knots and a tight, even grain.

All of Cedar Direct’s Canadian Western Red Cedar is graded according to the Pacific Lumber Inspection Bureau ‘R List’ Export Rules. We offer three main grades of Canadian Western Red Cedar cladding: Clear, #2 Clear / Better and #4 Clear. Unless otherwise requested, we combine #2 Clear and Better with #4 Clear as standard to provide what we consider to be the best quality and value for money product.

There are two notable drawbacks of Canadian Western Red Cedar compared to its British Counterpart – the environmental impact of importing from the Pacific west coast of British Columbia and the cost; Canadian Western Red Cedar can be twice as expensive as British.

So, in summary, Canadian Western Red Cedar would be the best choice for your cladding project if:

  • You are seeking a darker, more varied colour palette across your boards
  • You want the highest grade cladding available
  • You value the prestige associated with Canadian Western Red Cedar
  • Price is not a deciding factor

Wood durability

Durability is a measurement of how long specific species of timber would last if a 50mm x 50mm cross section was left in the ground unprotected. An untreated Oak beam, which is classed as 'durable’, for example, will last 15-25 years depending on environmental conditions. The following scale of durability was outlined by TRADA, the Timber Research And Development Association.

Durability Class designation Average service life
1 Very durable More than 25 years
2 Durable 15-25 years
3 Moderately durable 10-15 years
4 Slightly durable 5-10 years
5 Not durable Less than 5 years

Please select your preferred board width.

Cladding guide

It's worth noting that the width of your cladding will impact the price. Narrow widths result in more waste and additional workmanship so will be slightly more expensive per metre.

Please select your preferred board length.

Cladding guide

We aim to deliver at least 80% of boards at the lengths you have requested. The remainder will be mixed lengths – some longer and some shorter. A request for a high proportion of longer lengths will have a higher cost per metre because of restricted supply. A mixed length order will be the cheapest because of the ease of sourcing.

To keep delivery costs low we conform to standard UK pallet sizes.

Please enter the coverage you require in either linear or square metres.

Linear metres calculates the total metre run needed for a specific board width to cover a known square meterage. If you are not 100% certain of your calculations we suggest you include wastage at either 5 or 10%.

Please select your preferred wastage.

0% means you plan on having no waste and we will deliver precisely the linear or square meters you require. 5 or 10% wastage gives you a little leeway when trimming your cladding.

If you are unsure of the exact amount of linear or square metres you require we strongly recommend you add a percentage to take account of any 'wastage', otherwise you may not be getting an accurate representation of your costs.
