Trussed rafters provide the green
solution
Trussed rafters can contribute to reducing the environmental impact of a development.
Trussed rafters are highly engineered components that provide a structural framework to support a roof and are available for a wide range of buildings, both commercial and domestic, offering a versatile and cost-effective roofing option As timber is the only truly renewable building resource available today, using trussed rafters can contribute to reducing the environmental impact of a development

FSC and PEFC provide an assurance mechanism to purchasers of wood products that the wood used is from sustainably-managed forests.
Many Trussed Rafter Association (TRA) members use PEFC or FSC certified timber and are able to demonstrate this by having the Chain of Custody (CoC) certification.
This certification provides evidence that the timber originates from certified, well-managed forests and verifies that these products are not mixed with material from uncertified forests at any point in the supply chain, except under strict controls when percentage labelling is being used.
The TRA encourages its members to achieve CoC certification and supports the use of sustainably-sourced timber for trussed rafters.
Trussed rafters are also predominantly made from softwood from Sweden and Finland where both countries have a long track record in managing forest resources sustainably.
In addition to using sustainably-sourced timber, highly-engineered designs, which are made possible by the use of sophisticated software, mean that trusses are designed to minimise timber wastage by using less timber than traditional 'cut' roofs - saving on both forest resources and energy usage.
The manufacturing process, although advanced and efficient, is relatively low-tech which reduces emissions and pollution.
Timber trussed rafters also have greater thermal and energy efficiency than some other competitor materials such as steel, aluminium and concrete.
This, together with offering up to 65% more living space, enables land usage to be maximised with minimal environmental impact.
