Architectural preference for pitched roofs, coupled with concern about flat roofs, has encouraged specifiers and contractors to look to truss rafters to provide a solution.
The TRA said that many clients, specifiers and contractors now favour the use of timber in the roofs of small- to medium-sized commercial buildings such as schools, hospital extensions and supermarkets.
The organisation believes market development will accelerate with revisions to the British Standard BS 5268-3, due for publication, which will incorporate extended standard roof bracing details for spans over 12m.
