Why an air barrier system?
While many people believe that simply adding insulation is the best way to make a home more energy efficient, most traditional insulation products do nothing to stop uncontrolled air leakage. And uncontrolled air leakage has been proven to be the biggest energy vampire in almost any home. The U.S. Department of energy (DOE) reports that up to 40% of the energy cost of heating and cooling a building is wasted by uncontrolled air leaking.
Uncontrolled air leaking contributes to premature building deterioration, condensation, ice damming, poor air quality (IAQ) and mold growth. Most homeowners notice the problem through accompanying comfort issues such as chilly drafts, cold floors, or excessively dry or damp conditions. Building science experts agree than an effective air barrier system is the best way to substantially reduce both air leakage and the passage of moisture through the building envelope.
A residential study by ADVANCED CERTIFIED THERMOGRAPHY shows that Comfort Foam installations can reduce energy costs by as much as 60 percent each year compared to traditional insulation systems. Over 20 years, this can mean as much as $15,000 in savings at today's energy costs. With escalating energy costs, realized savings may be even greater.

"...Although many stories in the media attribute indoor air quality problems to houses being built too tightly, the reality is that homes need to be as tight as practical. Air leaking into and out of homes has created many of the problems. Moist air leaking out in cold weather can condense on wall and attic surfaces, creating mold growth and in some cases structural decay. This is a direct result of the home not being tight enough. Moist air leaking into a home in hot humid weather can have the same effect on finished surfaces of walls. Air leaking into a home from an attached garage has been shown to be a significant source of carbon monoxide in homes..."
The United States Department of Energy’s ENERGY STAR® program also recommends making homes more airtight to improve energy efficiency, comfort and indoor air quality while preventing mold infestations, wet attics and ice damming.
