Your home or office should have a well-sealed envelope to achieve the highest energy performance possible, which will provide you with the lowest utility bills possible! A building’s envelope includes the outer walls, windows and other openings. When a building is properly sealed and insulated, air leaks are minimized and your property is more affordable to operate with fresher indoor air quality.

According to, "Most homes in the United States don't have enough insulation and have significant air leaks. In fact, if you added up all the leaks, holes and gaps in a typical home's environment, it would be the equivalent of having a window open every day of the year!"

Shirley Air's air sealing and insulation services offer you the greatest indoor air quality and energy efficiency possible.

  • Air Sealing, unlike insulation, doesn’t involve filling spaces within your home’s infrastructure. It concerns the outer walls, windows, doors, and other openings, your home's or office’s envelope, where air can pass freely from the outdoors to the indoors and vice versa. When you create a well-sealed envelope in combination with the proper amount of insulation, you can greatly increase energy performance and reduce your energy bills.
  • Insulation prevents heat transfer between your home’s interior and the outside environment. Insulation is available in various forms including spray foam, cellulose and fiberglass. It is used to fill spaces within walls, floors and ceilings to reduce the convection and conduction of heat. All insulation has an "R-value", with the higher the R-value,or resistance to heat flow, the greater the insulation power. Call Shirley Air and our expert technicians will help you select the best insulation for your property. 
  • Crawlspace and Basement Air Sealing and Insulation: For a whole house or whole building solution, don't forget to have your crawlspaces and basements checked for air leaks. Shirley Air can inspect these areas at the same time we check your property's ductwork and other areas for air leaks and other potential problems. Check out our crawl space encapsulation system with vapor barrier to reduce moisture and improve the environment of the crawl space as well as the entire home. 

Our expert air care technicians will locate and seal any air leaks, evaluate levels of insulation, look for signs of moisture control issues, such as excessive mold and mildew, and use an infrared camera to find trouble spots in walls and ceilings. We will then create a service plan that incorporates whole building approach to make your residential or commercial property safer, more comfortable and energy efficient.
