Larch wood species and DIN designations

In the larches there are clear differences both between the individual species, as well as between the individual growth locations. Larchs from mountain regions are usually somewhat more stable, stronger and more durable than the larches from the lower areas. The most significant for the wood extraction is the euroean larch, besides, the American larch species and above all the Siberian larch still play a certain role.

Look

Grain

Larch wood can already be classified according to the place of growth based on the grain: mountain trees have very closely spaced, even annual rings, while the lowland trees usually have significantly wider and more irregular annual rings. The latewood zones can be designed very differently and also provide information about the hardness. With the very hard larch wood qualities, the latewood zones are about as wide as a third to a quarter of the width of the annual rings. Larch wood has no pores, but point-like resin leaks can be seen.

colour

Sapwood and heartwood are colored differently; like sapwood, the heartwood is also yellowish-brown to reddish-brown in color, but it darkens significantly and is then clearly recognizable.

properties

The larch wood from mountain areas in particular can be significantly stronger and harder than that from other growing locations. Larch wood has a very pleasant smell that comes from the resin. In principle, larch wood is also quite acid-resistant.

Shrinkage and drying

Larch wood shrinks only moderately, and the risk of cracking is low compared to other types of softwood such as pine. As a rule, larch wood dries relatively quickly.

resistance

Unlike many other types of softwood, larch wood is very durable and quite weatherproof (wood from alpine trees is even more so). In principle, larch wood is also resistant to fungal attack and is also very resistant to insect attack. Larch wood is also very durable, especially under water.

particularities

High resin content

As with many conifers, the sometimes quite high resin content of larch wood can cause problems when working. Staining or painting usually makes a previous resin removal essential.

use

Windows and doors are a very traditional area of application for larch wood, larch wood is also often used for floors because of its durability, as well as in furniture construction, especially when a rustic look is to be created. The predominant use is as solid wood, larch veneers are rather rare. Larch wood is also used industrially for chemical containers and in some special areas (cooling tower construction) because of its chemical resistance (acid resistance).

Prices)

European larch wood usually costs between 650 and 800 EUR per m³ as sawn timber, Siberian larch wood is somewhat more expensive (because of its higher quality, durability and hardness) and is around 750 to 900 EUR per m³. The most expensive are Canadian larch wood, for which you usually pay between 900 and 1.000 EUR per m³ must be expected.
