Aeroseal Envelope is an interior applied air sealing system that seals building envelope leaks up to 12mm. The waterborne sealant is aerosolised and injected into a pressurised home. The sealant is self-guided to the edges of visible and invisible leaks to create a seal by accumulating across the leak surface. The sealant is applied and dries quickly, before system cleanup is complete. This ensures construction can resume shortly after the process is complete with little to no impact on standard construction schedules. The Aeroseal Envelope system measures envelope leakage in real-time, enabling the system to dial-in specific air leakage requirements with precision and guarantee the results.

The Aeroseal Envelope 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.

Aeroseal Envelope modifies its blower door by adding a heater onto the fan. This allows the system to achieve optimal room temperature and humidity during the sealing process, allowing more sealant to be sprayed into the space for a faster, more efficient sealing process.

Aeroseal Envelope seals holes as large as 12mm, and as tiny as a human hair. Aerosol sealing is extremely effective at sealing narrow gaps and extremely small holes that are typically not cost-effective to seal manually, or that are missed using manual sealing techniques.

Our formula is a water-soluble organic compound and is proven safe. The sealant is ultra-low VOC and because it is inert there is no chemical reaction needed to form a seal meaning there is no off-gassing. With more than 150,000 projects sealed to date, we’ve helped hospitals, surgery centers, schools, and public buildings make sure their air is clean, healthy and comfortable – and saved them energy and money in the process. In fact, our sealant is GreenGuard Gold Certified, meeting the stricter certification requirements used in schools and healthcare facilities.

Aeroseal Envelope has been used in small apartments and hallways as long as 170m. As long as the space can be pressurised, it can typically be sealed. Additional blower doors can be added to increase the pressure in larger spaces.

The Aeroseal Envelope 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.

Aeroseal Envelope can be cleaned off surfaces. We recommend using a standard citrus based cleaner as soon as possible.

The area needs to be aired out for 90 minutes after the sealing is complete. During this time, the sealing equipment and coverings are removed.
