AeroBarrier

Project Description:

AeroBarrier is a cutting-edge envelope sealing system that simultaneously measures and seals building envelope air leakage. This product meets passive house airtightness standards, achieves airtightness requirements in less time without costly delays, as well as eliminating noise and odour complaints by concurrently sealing exterior and interior walls. AeroBarrier is a single-component, high-performance, synthetic, permeable, aerosol-applied sealant that performs as an air barrier around ceilings, floors, walls, windows, doors, and electrical and plumbing fixtures. It is UV stable, seamless, monolithic, and can be applied over a wide range of temperatures. AeroBarrier microscopically seals joints and seams of the building envelope from any gap of ⅝” to nothing.

The research approach for this project is to analyze the performance of the AeroBarrier sealing technology by conducting a series of air depressurization tests with the use of a blower door. The process will be to investigate why air leakages occur during finishing construction and if the AeroBarrier is affected. The experimental testing was conducted at the Minto Communities Arcadia low-rise residential construction site, on a block of 8 slab-on-grade townhouses. The chosen method for AeroBarrier application at this site and many others is to spray the product post-drywall. It should be noted that AeroBarrier may be applied at any time between rough-in and prior to occupancy. Although, the ideal time to apply AeroBarrier is pre-drywall or post-drywall. This experiment will demonstrate how the 1.6 ACH50 (Air Changes per Hour at 50 Pascals of pressurization) for a townhouse may fluctuate during the finishing construction stages and ultimately evaluate the performance of AeroBarrier. The goal is to find out where, when, and why air leakages occur after the AeroBarrier sealant is applied.
