What the experts are saying...

“In my professional experience as an Energy Rater (HERS Rater & LEED Green Rater), the standard building practice is to use open wall cavities for HVAC Return Air.  This practice brings with it the problem of Duct Leakage.  I believe the Eco-Air Seal solves the difficult challenge of testing for Duct Leakage, as mandated by the 2009 IECC, far more simply and cost effectively than any alternatives.”

“Chapter 4, Residential Energy Efficiency, of the 2009 IECC International Energy Conservation Code increases the requirements for HVAC duct systems in terms of testing and acceptable air leakage levels. These new requirements will improve energy efficiency in residential projects, but they make the Energy Code more stringent; so it will be more important than before to properly seal ductwork, especially return air ducts.

Eco Air Seal is an exciting product because it offers an alternative to the use of an all-metal duct system. I believe that Eco Air Seal is more cost effective; easier to install; and uses less natural resources than a full metal system while still providing the performance characteristics necessary to help meet the 2009 IECC Residential Energy Code; and to me this represents a win, win, win situation.”

“New-home sales are expected to increase to 368,000 this year from a record low 301,000 in 2011, and grow strongly to 575,000 in 2013. Housing starts are forecast to rise to 776,000 in 2012 from 612,000 last year, and reach 1.13 million next year”

“The 2009 IECC has been adopted by 30 of the 50 states as a prescriptive method of compliance for residential state energy code. In some cases, unless the tightness of HVAC ductwork is addressed, builders will not pass the necessary testing to receive a certificate of occupancy. In our experience, we have found it to be difficult to meet the requirements of the duct tightness section of the 2009 IECC Residential Energy Code without fully ducting all supplies and returns. If applied correctly, this product can help satisfy the duct tightness requirements without having to fully duct.”
