Residential Air Barrier Solutions

Think doors and windows are at the top of your heat’s escape plan? Think again. Walls, ceilings, floors and ducts can account for 90% of heat loss if not properly insulated.

Air leakage is one of the biggest sources of heating and cooling loss in a home. In fact, according to ENERGY STAR, if you added up all of the leaks and gaps in a typical home’s envelope, it would be the equivalent of having a window open every day of the year.

Coupled with insulation, air barriers are crucial for effectively limiting the air leakage in a home. Air barriers tightly seal the building envelope, allowing for an overall more energy-efficient space. Air barriers improve the air quality in your home and help keep moisture from spreading. Problem areas can include gaps around lighting fixtures, fireplaces, windows, where the flooring or foundation meets walls, or around wires. Green Building Advisor offers more information about the importance of air barrier installation, and why it’s critical to use a trained and professional installer to seal your home’s building envelope.
