Wood is the most environmentally sustainable building material
Its competitors – concrete, brick, aluminum and steel – are energy-intensive and have a high reliance on fossil fuels while wood, in comparison, is abundant, renewable, stores carbon and has low inputs to process.
It has strength to weight ratio 20 per cent higher than steel and four to five times higher than non-reinforced concrete.
Far less carbon emissions are produced in the manufacture of timber products than other building materials. By building a house in timber the carbon emissions saved, compared to other materials, are equivalent to running a car for seven years.
Wood insulates 15 times better than concrete, 400 times better than steel and 1,770 times better than aluminum, and is more efficient at heating and cooling.
