Location: University of Toronto- Hart House - Great Hall- 7 Hart House Circle, Toronto, Ontario M5S 3H3 Canada

Time: 8:00 AM - 2:00 PM

Owens Corning is running a free educational session on April 12 at the University of Toronto on the benefits of designing for acoustic comfort for multi-unit residential construction.

Tarion Builder Bulletin 19R (BB19R) requires condominium projects to undergo design and field review and reporting as of January 1st, 2017. This new version of BB19R builds on the previous version of BB19R, effective July 1, 2010. One of the major changes to BB19R, is the separation of Acoustical Review and Testing into a separate Risk Area to highlight the importance of warranty claim risks associated with inadequate acoustical performance. In addition to the revised Tarion requirements, the Ontario Building Code will feature new acoustical requirements as of January 1st, 2019. These new requirements will focus on system performance rather than component. The new language designers and builders/developers will need to focus on is ASTC (apparent sound transmission class) rating. This 3+ hour interactive session is intended to inform building designers, architects, consultants and builders/developers on the importance of Tarion BB19R conformance, how to design for ASTC ratings, and best practices in acoustical design/construction to limit risk and exceed performance.
