- Siberian Larch (Larix Sibirica)
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.
- European/American Oak (Quercus Alba)
The colour of oak heartwood is from light brown to brown. The heartwood is classified as class 2 durable (BS EN 350-2). The density ranges from 0.67 to 0.73 (g/cm3). Oak has been known as an excellent durable boat building timber for centuries. Today it is widely used for flooring, wine barrels, exclusive furniture and joinery. European Oak has a slightly higher price than Siberian Larch. Timber can get stained when in contact with metal fittings. European Oak is sustainably harvested.
