It is more stable than many other softwood as it rarely shrinks or twists, and it's low density makes it light and easy to work with. Has superb acoustic and thermal properties, Galvanized or stainless steel fixings are recommended due to the naturally occurring oils.
Rated BS EN 350 class 3 moderately durability (see below), naturally occurring ithujaplicins create the distinctive aroma and a natural toxic to fungi.
The species name plicata derives from a Greek word meaning "folded in plaits", a reference to the pattern of its small leaves.
Highly suitable for exterior cladding, landscaping work, decking, fencing, but it's equally at home being used as a internal cladding. Please note home grown cedar traditionally has more live knots than imported cedar. Should you require a hardwood or contemporary finish please see redgrandis.co.uk.
Durability is the ability of a species to resist decay either naturally or through preservatives. The Class is based on the ability of the heartwood (inner part of the tree) to resist fungal decay. The sapwood (the living outermost portion of the tree)is considered not durable and should not be used for external projects without preservative.
BS EN 350 has 5 classes of durability they are:-
Class 1 to 3 can be left as untreated timber, a natural ageing process will accrue e.g. Cedar will turn a grey colour. Class 4 and 5 will need to be treated with preservatives.
