Co2Timber European and British Larch European Larch Larix decidua or Larix europaea is one of the most durable species of coniferous wood. Owing to its slow growth rate it has an unusual durability for a softwood.

Owing to its high density Larch has an excellent wear and impact resistance rated BS EN 350 class 4 moderately durability (see below). It's ideal for cladding, flooring page, decking and landscaping projects commercially or for the home garden.

Please note home grown (British) Larch traditionally has more live knots than imported and Siberian larch. For Siberian please see Should you require a hardwood or contemporary finish please see Co2 Grandis.

The heartwood is pale reddish-brown to brick-red in colour, sharply distinct from the narrow, lighter coloured sapwood. It is a very resinous wood, with noticeably obvious annual rings a straight grain, and a fine, consistent texture.

It’s wholly sustainable with great supply routes from properly managed forests.

Larch is a like Douglas Fir, a good all rounder. It is good for joinery or furniture work. Super for flooring and excellent as air dried external cladding , looks great with a machined profile because it has a nice machined surface because the grain is nice and fine. Please note home grown Larch traditionally has more live knots than imported Larch.

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 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.
