TRA Releases Updated Roofing Guidance For Housebuilders

The TRA (Trussed Rafter Association) has announced and published a new roofing guidance for housebuilders.

“How to Build Compliant Spandrel Panels”, which is supported by the NHBC, has been brought up to date to include information about single-skin cladding for spandrel panels.

The roofing guide now has a page highlighting fermacell Gypsum Fibreboard as an example of how single-skin cladding can replace two sheets of plasterboard either side of a spandrel panel, without compromising fire and acoustic requirements.

Jonathan Fellingham, TRA chairman, said: “The first version of the guide we published last year proved to be very useful to housebuilders.

“We decided to update the guide to add more useful information for housebuilders on single-skin cladding options for spandrels. We take our collaboration with the installers of our products seriously and are committed to offering guidance to increase quality and accuracy wherever possible.”

Right through the roofing guide there are technical drawings and 3D renders showing safe and compliant installation methods for spandrel panels. Where needed, these have also been updated to show closer detail of bracing, and to demonstrate alternative ways to restrain spandrel panels.

Further guidance will be distributed throughout 2018 providing the latest advice on all aspects of the design, manufacture and safe installation of roof components.
