Spandrel Panels guide - Trussed Rafter AssociationToday many builders are exploring the efficiencies and quality benefits of pre-manufacturing and offsite construction.

As part of this drive, builders increasingly use timber spandrel panels in low-rise housing and apartments. Traditional brick and block gable ends and party walls are open to the elements during construction/curing and can’t be erected during certain weather conditions; particularly frost and wind.

There’s also the danger that they’ll be insufficiently cured before construction is continued which can be a major health & safety risk causing site accidents.

The new roofing guide for masonry-built homes provides evidence-based technical best practice on the design, structural requirements, fire and acoustic performance, weather protection and the safe installation of spandrel panels.

The advantages of using spandrel panels are numerous, but six key benefits stand out:

  • The panels can be manufactured off-site
  • They help to improve on-site safety, as there’s less time working at height
  • They can be installed quickly
  • Faster installation times mean lower costs
  • They leave little or no site waste
  • Using spandrel panels can help to address the shortage of skills on-site

To ensure safe and effective working practices, this document sets out some essential guidance on various aspects of spandrel panel design, construction and installation.

In particular, the guide aims to provide evidence based consistent information on best practice for spandrel panel usage in party walls above masonry.

The guidance has been prepared collaboratively by the Trussed Rafter Association and the Structural Timber Association.

The TRA represents over 65% of the trussed rafter and metal web joist industry in the UK and Ireland. Members include the principal manufacturers of trussed rafters, metal web joists, suppliers and professionals involved in roof and floor design and construction.
