UK Larch Cladding – Larix Europaea


UK Larch is a strong timber and has frequent dark knots up to 50mm in size. It has a high resin content and is not as stable as Siberian Larch as it can be prone to warping and twisting. Care should be taken if using for a cladding to order a cladding quality grade as there are lower grades available not suitable for this end use. UK grown Larch is also only rated as moderately durable so if being used externally you should take advice on the best way to protect your cladding from rot and insect attack. If left untreated, when exposed to rain and sunlight, it will go an attractive silver grey colour.
