Description

British western red cedar cladding offers a significantly cheaper alternative to Canadian cedar. Sawn or machined to profile, 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. Unlike most other coniferous softwoods, British cedar does not contain any resin so can take a range of paints, oils and stains. It is available in many profiles and can be installed both horizontally and vertically. Compliant with BS EN 14915 and BS 8605-1; CE marked. Grown in England and Wales.

Standard product features

Length:

Random lengths: 1.8 - 3.7 m.

Appearance:

British western red cedar has a pink-to-amber colouring with frequent dark knots. The colouring is paler, but more consistent, compared to the Canadian cedar. When left untreated, the cedar will bleach to a silver colour.

Technical properties:

  • Moisture content: 16–25%.
  • Natural durability (to BS EN 350-2): Moderately durable, Class 3.
  • Insect attack: Resistant.
  • Service life (to BS 8417): Occasionally wet: 30 years; frequently wet: 15 years.
  • Treatability class: Resistant.
  • Movement class: Small.
  • Resistance to impact: Low.
  • Resistance to fixing: Low.
  • Mean density (when dry): 330–390 kg/m³.
  • When to fix: No restrictions.
  • Grading: Too knotty to be graded under any standard.
  • Working properties: Good workability, takes fixings satisfactorily.
  • Extractives: Contains reactive oils, which will corrode ferrous metals. When the two come into contact, a blue sludge is formed that will stain the wood and anything else that it meets.
  • Emission of formaldehyde (to BS EN 14915): E1 (not significant).
  • Reaction to fire (to BS EN 14915): Euroclass F (untested), D-s2, d0.
