British Larch (Larix Deciduas) Durable Softwood
British larch ranges in colour from pinky-brown in the heartwood, to creamy- white in the sap band. There are frequent dark brown knots, which may loosen as the wood dries, resulting in open resin pockets that may ooze during the first year and during subsequent hot summers. When exposed to the elements, the wood will, over time, weather to a silver-grey colour.
British larch is a very strong and hard-wearing wood. When tested, it has proved to be up to 50% harder than common pine. The most beneficial characteristic of British larch is its natural durability, which results from its extremely high resin content.
British larch is ideal for traditional cladding profiles where it is used green (wet) and it offers good value for money when compared with hardwoods, such as oak or elm. British larch is not suitable for machined profiles because the knots tend to loosen and fall out during drying and machining.
BS EN 350-2 British larch is classed as moderately durable and is therefore recommended for external use without treatment as long as the sap is excluded. However, it is commonly accepted that the sap of larch is also suitably durable for use without treatment.
Workability: Straight-grained boards can be prone to splitting. High resin content precludes the use of many finishes. Knots (especially on the arris) can fall out of dry boards.
