New in 2025: BuildGreenCT’s Lunch & Learn Series will spotlight specific topics, products, and solutions brought to you by our Annual Sponsors.
Join us for our inaugural Lunch & Learn Webinar: Foam Free High Performance Building Enclosures on February 20th from 12-1pm. In this presentation, John Deans of 475 Supply will dive into the challenges foam insulation can present in passive building design and the building science behind great, resilient assemblies.
Foam insulation, dominant in today’s high-performance marketplace, is increasingly recognized as hindering building performance demands of air, vapor, and thermal control. Practitioners are therefore wanting and finding new solutions that virtually eliminate foam and provide greater performance.
This webinar presents a clear and practical guide to achieving the highest levels of resilient and sustainable building enclosures while eliminating foam. After only an hour, you’ll leave with an AIA HSW credit and a newfound practical understanding of how to achieve the highest levels of sustainable building enclosures while eliminating foam.
Attendees will be able to:
- Define what qualities differentiate high-performance enclosures from typical construction and how those qualities are evolving.
- Describe practitioner concerns of foam insulation hindering efforts to meet the evolving high-performance qualities.
- Describe how a foam free enclosure can more robustly achieve the qualities of high-performance.
- Describe practical methodologies practitioners can implement, to successfully produce a high-performance enclosure that is foam free.
