Overview
Western Red Cedar (Thuja plicata)
This species is an ideal material for use as exterior or interior cladding and is available with PEFC & CSA certification.
Western Red Cedar is naturally resistant to decay and insect attack. It simply seasons if left uncoated to an attractive silver grey appearance over a period of approximately eighteen months in areas with low air pollution. Cedar offers superior acoustic qualities too, helping to reduce noise or confine it to specific areas. It is also an excellent material for thermal insulation in summer keeping the building cool and in winter preventing the heat from escaping.
