British western red cedar

British cedar cladding | VHL7  Weathered British cedar cladding 

The majority of western red cedar cladding seen in this country is imported from North America and Canada. However, British cedar has been grown in our woodlands for over one hundred years and the mature trees are ideal for timber cladding production. As Canadian cedar becomes increasingly expensive, our British cedar cladding offers a significantly cheaper alternative and avoids the substantial environmental impact of shipping timber to the UK.

For a comparison between British and Canadian grown western red cedar watch our new video.

Freshly cut or machined, British cedar cladding has frequent small- to medium-sized dark knots and an amber colouring which, if left untreated, will bleach to a silver colour. It is faster grown than imported cedar and is therefore softer. Unlike most other coniferous softwoods, British cedar does not contain any resin so can take a range of paints, oils and stains.
