New Technology for Efficient Multifamily Building Envelope Sealing

This webinar covered findings from CEE's recently completed field study demonstrating the abilities of an aerosol sealant to seal leaks in building walls, floors, and ceilings in multifamily applications. Discussion includes recommendations on how utilities and contractors can take advantage of this new sealing application.
About the Research:

While tight envelopes have become standard for Minnesota single-family homes, these construction practices are just starting to be applied to the multifamily sector. Multifamily buildings have many of the same leakage paths as houses, with additional paths hidden in walls or other cavities that are difficult to seal with conventional methods.

Researchers at UC Davis Western Cooling Efficiency Center developed an aerosol sealant to seal leaks in building walls, floors, and ceilings. The process has the potential to be more effective and convenient than conventional methods for sealing envelopes, as it requires less effort and provides greater leak coverage. CEE and the Western Cooling Efficiency Center recently complete a field study demonstrating the abilities of this new technology in multifamily applications. Results showed a reduction in leakage of 67% to 94% for 18 new construction units and an average of 68% for nine existing units.
