CSA Group’s Paul Gulletson gives Top Glass attendees a peek at the upcoming A500 Building Guards standard. The second annual event is being held at the International Centre in the Greater Toronto Area.

An increased number of building guard failures in the Toronto area over the past few years—many involving glass infill panels falling catastrophically—has drawn a lot of attention and scrutiny of late.

So the Canadian Standards Association (CSA) is working to develop a standard to address the growing concern.

Paul Gulletson, project manager at the CSA Built Environment Group, gave today’s Top Glass Conference and Exhibits attendees a sneak peek at the new CSA A500 Building Guards standard, which is set for publication later this year. The Top Glass event, now in its second year, was held at the International Centre in the Greater Toronto Area.

During the presentation, Gulletson noted that CSA staff does not write the codes, but rather a technical committee is established, comprised of experts in the industry—a balance of architects and engineers, regulators, suppliers, fabricators and users.

He added that the benefit of creating “a harmonized, consistent approach” with A500 “will facilitate work for regulators, reduce uncertainty for designers, make designs more consistent, make installations more reliable and, ultimately, increase public safety.”

Some typical challenges in glass guard designs, Gulletson said, are issues with fasteners, connections to surrounding structures and connections to glass components.

Responsibilities for the new standard fall on designers and fabricators, alike, as it includes considerations of materials and components, design requirements, deflection and geometry. He adds that glass requirements include references to CGSB 12.20 and ASTM E1300 and apply to all types of glass.

Testing requirements in the standards include procedures, guard load, impact resistance, post breakage retention, anchors and fasteners, as well as on-site and documentation.
According to Gulletson, A500 is expected to go to public review in June, be approved sometime this summer and published by fall or winter.

The Top Glass show floor featured more than 40 industry exhibitors, and other seminar topics included challenges in façade glazing, off-shore curtainwall glazing challenges and opportunities, and challenges unique to large applications of glass.
