Timber are large stems from trees that can be sown up to sawn timber, so we can build houses and other constructions.
Timber is usually coarser logs than those that go to pulpwood and the requirements for straightness, freshness, lack of rot and disturbing twigs are also higher on timber. Timber can in turn be divided into a number of different ranges depending on the size and the shape of the product.
In Sweden we have a long tradition of building wooden houses. About 90% of all small houses (smaller one-storey houses) built in Sweden have been built with wooden frames. Today, more and more multi-storey houses, sports halls and bridges with wooden frames are being built. The wood material is both light and strong, which also makes it useful for additional building on existing houses in the urban environment, where there is a lack of space to rebuild. More information about building with wood and more can be found at the organization Swedish Wood’s web site www.swedishwood.com.
When 1 cubic meter of wood is used as building material instead of cement, metal etc., we reduce carbon dioxide emissions to the atmosphere. This is called substitution effect, we change something with a high environmental impact to something with less environmental impact. When 1 cubic meter of wood is used instead of cement, CO2 emissions decrease by 1 500 kg. The corresponding figure for metal is 1 000 to 1 500 kg of carbon dioxide.
