Siberian Larch grows in Siberia, Europe and in North America (as Canadian Larch) and has a high natural resistance against decay. This has been shown in scientific investigations as well as from archaeological discoveries and practical observations.
The harsh climate in Siberia results in very hard durable timber with a density of 0.64 (g/cm3). Higher density makes it more difficult for the organisms that cause decay to penetrate the wood.
Siberian Larch is widely used as a durable timber for windows, decking and weatherboards.
