Air distribution is a part of a construction project that is often ignored, yet accounts for up to 30% of the HVAC energy utilized. Building construction has employed thermal transmission reduction initiatives though the emerging energy codes, but most ducting systems in the US have not even achieved the performance of the average windows being installed today. When you combine the thermal performance with air leakage rate experience...your existing duct is letting you down.
More imminent in most duct systems is migration of water into the air passage system. The proof is on the roofs of buildings that employ outdoor ductwork. As duct systems leak, they inflate and deflate the outer protective layer that is intended to provide water integrity. Over time...the performance of the moisture barrier degrades to a point where moisture is allowed in. Moisture reduces the performance of the insulation and augments microbial growth either on, or in, the duct.
KoolDuct offerings of industry solutions like no other that meet or exceed the ASHRAE and ICC Energy Codes not only today...but 10 years from now.
