Typical House Sources of Air Leakage

Make room for a revolutionary insulation material. Not long ago, very little thought was given to the type of insulation installed in homes. But, families today face problems that weren’t even issues when conventional insulation was developed: rising energy costs, unwanted noise, allergies, asthma and mold. Times and attitudes are changing. Homeowners, like you, are beginning to appreciate the increasingly important role insulation plays in their lives. People consider their homes as a safe haven – a place where they can escape the noise and pollution of modern everyday life.
Consequently, insulation must play a multiple role. No longer there just to insulate, today’s insulation must protect a home by providing a Healthier, Quieter, More Energy Efficient® environment. What’s more, today’s insulation should address a real threat to occupant comfort and health – that real threat is air leakage. It has been documented that enough air escapes from a typical house every day to fill two Goodyear blimps (www.urbanoptions.org). And, extra insulation means little without an effective air barrier! Unlike conventional insulation, Icynene® is an insulation and air barrier system that protects both new and existing homes from the adverse health and economic effects of air leakage.

I am SO glad I decided to use Icynene to insulate the entire envelope of my house. We did a full-renovation, and the 100% air barrier has been fabulous. Ameri-spec tested our house for the federal renovation grant, and said we were more heat efficient than most of the new "green" homes going up on the west side. Icynene definitely contributed to the $3800 rebate we got.
