Sealing Ducts Repairs and Installations with Aeroseal
In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 percent of the air that moves through the duct system is lost due to leaks and poorly sealed connections. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.
Because some ducts are concealed in walls and between floors, repairing them can be difficult. However, exposed ducts in attics, basements, crawlspaces, and garages can be repaired by sealing the leaks with duct sealant (also called duct mastic). In addition, insulating ducts that run through spaces that get hot in summer or cold in winter (like attics, garages, or crawlspaces) can save significant energy.
Fortunately, there is a even better solution: Aeroseal Duct Sealing. This innovated, patented technology — developed at U.C. Berkeley with funding from the Environmental Protection Agency and the U.S. Department of Energy –stops leaks from the inside out. In fact, this breakthrough technology is so effective that the Department of Energy included Aeroseal among the most beneficial energy technological advances ever developed. Aeroseal has also been honored with Popular Science Magazine’s “Best of What’s New” and the Department of Energy’s “Energy 100″ award
