Due to it adaptability there are thousands of situation which lend themselves to cladding with timber rather than PVC or alternative materials.
When selecting your timber type for your project it is worth taking in to consideration BS EN 350 timber durability class.
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 Very durable (Such as Tropical Opepe and Iroko)
- Class 2 Durable (such as Co2 Cedar Cedar) Co2 Grandis
- Class 3 Moderately durable (Such as European larch, Cedar (UK), Co2 Larch ® Siberian Larch, North American Douglas Fir)
- Class 4 Slightly durable (Such as Home Grown (UK) Grow Douglas Fir)
- Class 5 Not durable (Such as Sitka Spruce)
Class 1 to 3 can be left as untreated timber, a natural ageing process will accrue e.g. Larch will turn a grey colour. Class 4 and 5 will need to be treated with preservatives.
