Will sealing my building with spray foam cause indoor air quality problems?

Your building does need to be ventilated in order to maximize the quality of indoor air (moisture levels and contaminant levels). Most design professionals will advise you to seal the structure as tight as possible and provide the necessary ventilation through the heating and air conditioning system. Many systems employ a highly energy efficient "air exchanger" which is designed to pre-condition (either warm or cool) the incoming outside air with the outgoing exhaust air. In this manner, you can build an extremely energy efficient exterior shell using high performance spray polyurethane foam while still providing controlled and energy efficient ventilation.

With Icynene in our townhouse, our energy bills are 35% less than our neighbors who used fiberglass. And with the addition of an air filter, our son is having less asthma attacks.
