Attic Insulation and Air Quality: What You Need to Know

When warm, stale indoor air leaks into a cool attic space, it condenses and creates moisture. The moist attic insulation then becomes a breeding ground for mold and mildew, which can then spread to living areas. The spores that these organisms release can irritate lungs and cause respiratory problems in people with asthma or other respiratory conditions. Additionally, if the insulation is old or contaminated, it can release fibers into the air which can also aggravate health symptoms.

Gaps in insulation and wall cavities allow outdoor air to enter return ductwork, carrying with it dust, pollen, vehicle exhaust, allergens, and other pollutants. These irritants can be pulled through your HVAC system and recirculated throughout the house, clogging filters sooner than normal.

Having an adequately insulated attic helps prevent this infiltration. In addition to reducing your energy costs, proper attic insulation can improve IAQ and extend the life of heating and cooling systems. As more homebuyers prioritize energy-efficient features, a well-insulated attic can boost your home’s resale value.
