Describes a recently developed technology from California which provides a way to duct seal installed residential systems in two to three hours. The Aeroseal technology uses a fan to blow a small quantity of dry adhesive particles through the temporarily seald duct system. With registers and the furnace blocked, the suspended sticky particles travel in the airflow toward the only place left for the air to exit - the cracks and leaks. As the air stream turns sharply through leaks, the particles are deposited directly on the edges of holes to create seals.
