2018 HPC National Conference Session

Automated House Sealing : Aerosol Envelope Sealing of New Homes

Thursday, April 26
8:30 AM - 10:00 AM
Location: Franklin 2 (4th Floor)
CEUs: BPI, InterNachi, NARI, ASHI

This session will discuss the overall objectives and interim results of a Building America project focused on integrating a new technology for automating the building sealing process in new homes. The technology simultaneously measures, locates, and seals leaks in a building remotely with demonstrations showing 80% leakage reductions with under two hours of injection.
The Building America project team is working directly with builders to identify the best stages for incorporating aerosol sealing, from the perspectives of cost, performance, and seamless integration into the construction process. The cost of the aerosol sealing and resulting house tightness are compared to similar group of houses using conventional sealing methods. In addition to producing tighter houses, conventional sealing methods are evaluated to determine whether they can be eliminated or reduced to further improve cost effectiveness. This talk will present the results of the initial sealing demonstrations for builders in California and Minnesota.
