FAQs
The entire AeroBarrier process, from setup to completion, takes approximately four-hours for a typical single-family home. When targeting reduced envelope leakage levels of Passive House or ZERH, additional time may be required.
AeroBarrier may be applied at any time between rough-in and prior to occupancy. Although, the ideal time to apply AeroBarrier is rough-in or post-drywall. Other factors that affect install is the build process (i.e. vented or unvented attics) and the site’s climate zone.
If AeroBarrier is applied at rough-in or right after drywall is installed, there is very minimal preparation required. Vertical surfaces like walls, doors and windows require no covering. All designed openings, such as ducts, electrical and plumbing, need to be covered prior to sealing. All finished horizontal surfaces need to be covered.
The AeroBarrier sealant is based on a waterborne acrylic that has been used as a fluid-applied permeable air barrier for many years. The sealant is GREENGUARD Gold certified and has been tested according to various ASTM standards and NFPA 285 for fire spread, smoke production, adhesion, antifungal properties and tensile strength. The sealant is ultra-low VOC and has no off-gassing.
The AeroBarrier system uses a modified blower door to measure envelope leakage during the process. The blower door is calibrated to meet ASTM Standard E779, E1554, CGSB-149.10-M86, EN 13829, ATTMA Technical Standard 1, NFPA 2001, RESNET and USACE.
Third-party lab testing reveals AeroBarrier withstands a simulated 50-year durability test, with little or no seal degradation. Click here to see the durability test results.
The area needs to be aired out for 30 minutes after the sealing is complete. This is done by opening doors and windows while running the fan. During this time, the sealing equipment and coverings are removed.
