Welcome to the fourth issue of Supplying Timber, a magazine from Timber Development UK (TDUK) dedicated to the timber merchants, suppliers, manufacturers and tradespeople who are interested in working with timber.
Visual grading standards might be used for in-situ assessments or for grading timber from unusual sources, like minor species or post-consumer wood. There are limitations to using visual grading standards for such purposes.
Certifications like the Forest Stewardship Council (FSC), the Programme for the Endorsement of Forest Certification (PEFC), and Grown in Britain prioritise small-scale forests, are verified against international benchmarks, and aim to improve livelihoods and conserve ecosystems while mitigating negative environmental impacts.
Tree species are known by a variety of regional, trade, and scientific names, which can cause confusion. Using the correct names, in an unambiguous way, is essential to specify the correct species and ensure it is supplied.
Thanks to the variety of different tree species globally, timber can vary in colour, density, and performance depending on its source. These variations in timber due to species determine the suitability for different construction uses.
Timber is a renewable construction material that comes from trees. Species of tree differ in their anatomy due to different evolutionary histories. These differences create timber with varying characteristics and properties.
Many tree species can be identified by their differing anatomies. Softwoods, hardwoods, and wood-producing monocots show different physical features, enabling the wood of individual tree species to be distinguished based on anatomy.
