Timber is a versatile and high performance construction material that can be produced in most parts of the UK. This second edition of ‘Sustainable construction timber’ has been written to help building designers and contractors source and specify local timber products. The report explains why local sourcing of timber is important, reviews the range of timber species and products currently obtainable in the UK and explores the ways in which local sourcing can be achieved within a construction project. Sustainable construction timber is applicable to designers and contractors wanting to source and specify UK grown timber products, people considering using their own timber on a construction project and those involved in building refurbishment or conservation.
