While there are many roof construction options available, trussed rafters are a truly sustainable choice.

What makes trussed rafters sustainable?

Both trussed rafters and metal web joists use specially designed lightweight engineered steel plates and webs to form the structural joints between their timber members. When the products are used, precious resources are being maximised to their full potential. When the products are finally removed during renovation or demolition they can be easily dismantled, reused and recycled.

Trees constantly absorb carbon dioxide from the atmosphere. Even after trees are cut down, timber and wood-based products such as trussed rafters and metal web joists continue to lock in the carbon dioxide for the whole life of the residential or commercial building in which they are installed.

As well as being an ideal solution to help fight climate change, wood-based products are both light and strong which makes them ideal for use in construction.

What’s more all of the timber used in our members products is legally sourced and comes from sustainably managed forests. This means that the suppliers always ensure new trees are being planted as fast as they are being used.

Most TRA members can also offer their customers the benefit of PEFC or FSC chain of custody certification. Ask your chosen TRA member for more details about where they source their sustainable timber. Or visit each members TRA page to see details of their Chain of Custody certification.
