How is air sealing related to insulation and energy efficiency?

Is your home as energy-efficient and comfortable as it should be? If it isn’t properly insulated and sealed, it isn’t! Homes that don’t have enough insulation and sealing are more vulnerable to heat loss and air leakage.

When it comes to maximizing the energy efficiency, you should ideally both insulate and seal your home. In fact, air leaks undermine the performance of insulation, so homes that are insulated but not sealed aren’t doing much to help increase overall energy efficiency.

Insulation & Sealing

Common Sources of Air Leaks

Places in your home where you can usually find air leaks include:

  • Attics
  • Crawl spaces
  • Around windows and doors
  • Duct vents
  • Dryer vents
  • Fireplace flues
  • Where the chimney and siding meet

Common Places to Insulate

Not surprisingly, some of the most common places to insulate are where air leaks commonly occur:

Usually, if your home is drafty and uncomfortable (particularly near the windows), temperatures are uneven from room to room or the second floor is unusually hot and stuffy, chances are your home isn’t adequately insulated and sealed.

Benefits of Insulation & Air Sealing

Increasing the energy efficiency of your home and helping reduce utility bills are the major benefits of insulating and sealing homes. But there are other benefits as well.

Installing insulation and sealing air leaks can also help:

  • Your home stay comfortable all year long
  • Reduce noises from outside and between different rooms and levels inside
  • Reduce the amount of pollen and dust entering your home
  • Control humidity levels
  • Lower the risk of ice dams forming on the roof
