Blown insulation installationYou can invest in a high-efficiency air conditioner or furnace — but in reality, it’s only going to be as efficient as your home’s air sealing and insulation. That means you could still be sending a lot of cool air or heat (and money) out the doors, windows, attic, and walls of your home!

It’s essential to have proper insulation R-values to help keep warm and cool air inside your home and keep the cold and hot weather out.

Insulation Basics

Proper insulation will help you to live greener, save money, and be more comfortable year-round. Here are some insulation essentials you should consider:

  • Attic insulation – This should be at 10 to 12 inches; most homes have only 5 or 6 inches.
  • Exterior wall insulation – Most homes built before 1945 have no insulation in the exterior walls, which allows a lot of air into your home.
  • Rim joist – Located where your foundation meets the first floor, a lot of homes lose significant energy here because the outside air can easily infiltrate. We use a spray foam that gets into nooks and crannies that the old-style batt insulation can’t fill.
  • Air sealing – If most homeowners added up all the cracks and gaps in their house, it would be the equivalent of a one square-foot opening. That’s a lot of air loss and infiltration! Air sealing can close those gaps while also improving air quality.
