Research from the U.S. Department of Energy (DOE) has consistently shown about 30-40 percent of the air traveling through ductwork leaks, and if air is being pulled from somewhere, like a dirty crawlspace, it is going to effect IAQ.
Designed for flexible duct media, Eco-Touch® insulation delivers thermal and acoustical characteristics to HVAC systems in residential and commercial settings. It is designed with an impervious inner air barrier film, which prevents insulation from entering the airstream, reducing the possibility of further air friction loss.
Over the last 10 years, there has been a growing trend toward using insulated products like fiberglass duct board and flexible duct, especially in the new construction market. Today this trend is continuing because of the emphasis on the whole-home approach to energy conservation and home performance contracting.
