Pine – an extremely tough wood

Pine – an extremely tough wood

The pine is often exposed to very strong winds, as it often grows by the sea or in high mountains, which makes it extremely tough.

Larch – a native wood and more versatile than ever

Larch – a native wood and more versatile than ever

The larch is a typical tree of the mountains and a mixed tree species. With a medium density, it is the heaviest and hardest native conifer (with the exception of yew).

General information

The larch is a typical tree of the mountains and a mixed tree species.
With an average gross density (rN) of 0.60 g/cm3, it is the heaviest and hardest indigenous coniferous wood (with the exception of yew).
Due to its high density, larch wood has good elasto-mechanical properties. In addition to its high load-bearing capacity, it is also highly resistant to weathering.
It accounts for around seven percent of Austria’s productive forest. Larch is said to live for over 800 years and is harvested as timber after 100 to 140 years.

Wood characteristics

The light sapwood (sapwood is the wood in the outer trunk area of a tree before its bark) of the larch is very narrow, the color of the heartwood varies greatly from light brown (so-called grass larch) to intense reddish brown. It darkens considerably. The earlywood/latewood contrast within the growth ring is pronounced, whereby the latewood proportion can be 1/ 2 to 1/ 3 of the growth ring width.
The fine resin canals are primarily found in the latewood.

Characteristics

Larch wood has very good strength properties, but these vary greatly depending on the location, as does the density (400 to 820 kg/m³), which averages 550 kg/m³. The wood is considered to be medium hard (Brinell hardness 19 N/mm²) with good stability. Larch wood is easy to dry and process, although pre-treatment with resin-dissolving agents is sometimes necessary for surface treatment. Due to the hard knots and irregular grain, there is a risk of splintering and tearing. Pre-drilling is recommended as the wood splits easily. In terms of durability against fungi, larch is in class 3 to 4 (moderately to not very durable) and is often overestimated due to its great variability. The impregnability in the heartwood is very poor, in the sapwood moderate.

Usage

Larch wood is used for both exterior and interior applications, both load-bearing and non-load-bearing. It is used for highly stressed structural components as well as in boat building, bridge building, earthworks and hydraulic engineering. In interior construction, it is used for windows and doors, flooring, cladding and furniture. Recently, exterior cladding made of larch has become very popular, which, left natural and unprotected, turns gray after a few years.
