Seeking Perfection in Air-Sealing

The invention of the blower door was an important step in minimizing thermal losses from buildings. By depressurizing the envelope and using tracer smoke, we can find the air leaks and seal them. A new method has emerged that seals air leaks using an aerosolized acrylic caulking and pressurization, sealing even hidden leaks. Join us in a discussion about the advantages of both methods, best practices, and real world examples.
