What is AeroBarrier?

AeroBarrier is a cutting-edge envelope sealing system that simultaneously measures and seals building envelope air leaks.

How It Works


Temporarily block windows and doors; cover electrical receptacles and switches; protect finished surfaces.


Spray a fog of sealant particles that travels to the air gaps and holes.


Pressurize the space and its air leakage with a computer-controlled atomization system.


Allow the particles to build up around any gaps and holes to seal leakage areas without coating surfaces.
