In this episode of the HVAC Know It All Podcast, host Gary McCreadie is joined by Gord Cooke, President at Building Knowledge Canada, and Ian Walker, Sales & Marketing Manager at Aeroseal, to talk about air sealing technology and how it improves building performance. They explain how AeroBarrier works to reduce air leakage and why airtight homes need proper mechanical ventilation. The conversation covers common concerns about sealing homes too tightly, the role of HVAC systems in fresh air control, and how ventilation systems like ERVs help maintain comfort. Gary, Gord, and Ian also share real job site examples, costs, and how better air sealing can improve energy efficiency and system sizing.

In this conversation, Gord and Ian explain how AeroBarrier is used to seal air leaks in homes and improve building performance. They describe how the system uses pressure and a misted sealant to find and close gaps, while stressing the need for proper ventilation to maintain air quality. Gord, Ian, and Gary discuss common concerns about making homes too tight and explain why controlled ventilation is important. They also cover real job site examples, costs, and how reducing air leakage can improve comfort, energy use, and HVAC system sizing.
