SFS technical guide aims to address quality concerns

15th April, 2019

Installation concerns about steel framing systems (SFS) are addressed in a new technical guide produced by FIS, trade body for the finishes and interiors sector.
The updated guidance on the design and installation of light steel external wall systems was created after competence and quality issues were highlighted by the Oxgangs Schools wall collapse in Edinburgh and the Grenfell Tower fire, FIS said.

“SFS is seen as non-load bearing, but it is supporting cladding, internal linings insulation and even services,” the trade body explained. “There are significant implications should it fail, which could lead to the external cladding falling off.

“The report on the collapse of the brick cladding at Oxgangs Primary School Edinburgh on 29 January 2016 highlighted that there was a failure in the correct installation of a simple element: wall ties. Although there are no direct examples of this happening where SFS has been installed, it highlights the danger of ignoring the correct installation process.”

The guide, which FIS produced with the Steel Construction Institute (SCI), includes sections on:
• Light steel sections
• Structural design
• Setting out, tolerances and movement
• Fixing details and fasteners
• Installation
• Health and safety
• Continuous walling
• Secondary steelwork.

“SFS has been around for over 20 years, and many projects are using it, but there are problems being created because of a lack of planning and knowledge,” said Joe Cilia, technical director at FIS.

“SFS is the first thing you see, but often the last thing that’s designed in a building. This guide is an example of how the supply chain can work together to share knowledge, support training and deliver quality.”

FIS said the guide aims to spread best practice, help raise standards, educate clients, designers and installers, and will also be useful to anyone involved in quality checks, such as clerks of works.

“The document includes check lists and guidance, and will give installers the confidence to question designs,” FIS added.

The Solid Wood Solutions event reflects the swift upward trajectory that materials such as cross laminated timber (CLT) are now on as a sustainable, structural alternative to steel and concrete.

Solid Wood Solutions shines a spotlight on pioneering projects through informative case studies presented by those who conceived and developed the buildings that are gaining global attention. 

As engineered timber technology is one of the fastest growing offsite methods of construction, this event is designed to inspire through innovation. The event consists of a bespoke exhibition of circa 25-30 companies from within the CLT, LVL and glulam technology sectors, plus complementary solutions such as SIPS and cladding/fenestration solutions with a conference of approximately 150 delegates.
