The Fenestration and Glazing Industry Alliance (FGIA) will host a webinar entitled “The Impact of Cavity Reduction on Triple Glazed IG Units” on Tuesday, March 9 at 11:30 a.m. Eastern.

During this webinar, attendees will learn about the recent study commissioned by the Natural Resources Canada (NRCan). It was undertaken to help insulating glass unit (IGU) manufacturers understand the impact that glass deflection can have on the energy performance of triple glazed IG units. This webinar is complimentary and open to the public.

NRCan contracted with the presenter, Jeff Baker, President at WESTLab, who will cover highlights of the study including:

  • Examination of variables that impact glass deflection to determine which variables have the largest impact on the deflection and could be factored into the IGU design to minimize the impact on the energy performance of IGUs
  • Focus on the changes in U-factor resulting from glass deflection under winter conditions
  • Development of a spreadsheet tool to allow IG manufacturers to study their own products and examine their designs

Additionally, Baker will review the research and results of the study and demonstrate the spreadsheet tool that serves as an integral part of this NRCan report.

Register now for this webinar. FGIA’s Marketing team will live-tweet this presentation from FGIA’s Twitter account, @FGIAonline, using the hashtag #FGIAwebinar.
