Western red cedar exterior cladding which is one of the most popular external claddings, due mainly to its vibrancy of colour, its resistance to decay and high level of durability. If it is left untreated it will weather naturally to a silvery grey or darker grey colour; alternatively it can be prefinished and stained before installation to avoid the weathering process.


PEFC/FSC Certified on request.
