475 Presentation: Foam Free High Performance Building Enclosures

Foam Free High Performance Building Enclosures presents a clear and practical guide to achieving the highest levels of resilient and sustainable building enclosures while eliminating foam.   The growing performance demands of air control, vapor control, thermal control, health and sustainability are examined.   Foam insulation, dominant in today’s high-performance marketplace, is increasingly recognized as hindering many of these building performance goals.  Practitioners are therefore wanting and finding new solutions that virtually eliminate foam and provide greater performance.  This presentation is a careful look at how to do it.


Learning Objectives:  Upon completion participants will be able to:

    1. define what qualities differentiate high-performance enclosures from typical construction and how those qualities are evolving.
    2. describe practitioner concerns of foam insulation hindering efforts to meet the evolving high-performance qualities.
    3. describe how a foam free enclosure can more robustly achieve the qualities of high-performance.
    4. describe practical methodologies practitioners can implement, to successfully produce a high-performance enclosure that is foam free.

Who Should Attend:

    • Architects
    • Facade/Enclosure Consultants
    • Designers
    • Builders
    • Building Science Consultants
    • Air sealing contractors
    • Insulation contractors

    My inquiry is for a two family retrofit home. Our primary goal is air sealing to eliminate exchange of air between unconditioned and conditioned space. Reduce stack effect and improve air quality and energy efficiency. lHeat and hot water appliances and laundry occupy this full height basement which gets occasional moisture penetration. Slab foundation. No insulation on walls. Could “The system” be used on the basement ceiling to accomplish these goals? (New England climate)

      Thank you. I will be in touch next week.

    Zeke, yes the system would work well in your situation to completely eliminate the air exchange between the basement from the rest of the house. Retrofits are more challenging since there might be existing partitions and pipes that you need to work around.

    Depending on the humidity levels of the basement you can use INTELLO Plus (when basement is relatively dry) or use DA membrane when basement is more humid.

    Connecting to the foundation, and airsealing that connection/the foundation itself, will help as well to increase comfort and IAQ. Please send us some pictures if you would like further specific recommendations.
