The Formula Behind the AeroBarrier X1 Sealant

AeroBarrier X1 sealant is a stable, non-toxic, airborne-applied, waterborne acrylic sealant. It is atomized into small particles that deposit only at the leak sites and build to form a complete and tight seal, remaining firmly in place for years while staying completely pliable and flexible.

The X1 sealant:
• Ultra-low in VOC – no off-gassing
• GreenGuard Gold certified and is safe to use in any type of building
• Built Green certified
• No flame spread / no smoke spread
• Made in Canada


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.
