Why You Should Air Seal Before Insulating

Air Seal Before Insulating

Atlanta, GA homeowners focus on upgrading their insulation, but before adding fiberglass, cellulose or spray foam insulation, they should consider getting the house air sealed. This is the first step toward reducing energy waste and saving money on heating and cooling bills.

The biggest reason to do this is because of how much heat escapes a home through cracks and holes. In fact, Sealed’s home energy audits show that the average house exchanges air at a rate 3-4 times greater than it needs to, which is like leaving a window open in your house 365 days a year!

Insulation alone won’t stop this unwanted flow of air, but it does slow down the movement of heat. That’s why the 2012 and 2015 IECC include air sealing as a key component in the building envelope system.

When paired with insulation, air sealing reduces drafts and improves comfort by regulating temperatures in different parts of the house. It also prevents moisture and mold problems by keeping outdoor pollutants, allergens and humidity out of the house.

Air sealing can be done by a professional or by the homeowner. The most common locations for this work are doors and windows, where caulking is needed to address leaks. Other places are where electrical wiring and plumbing come through walls or into the ceiling, ducts and soffits over cabinets, or outlet and switch plates where foam gaskets can be installed. When performed properly and by an experienced contractor, there is virtually no risk of over-tightening the house or causing health concerns.
