Although this is a question you don’t think about on a day-to-day basis (and you may not be able to answer), it’s important when it comes to your home’s energy efficiency.

Do You Need More Insulation for Your Attic?

So how do you know if your attic has enough insulation? One of the easiest ways to tell if you need more attic insulation is by poking your head up there and taking a quick look around. If you can see your floor joists (if the insulation is level with or below them), you probably need more insulation.

Other signs that indicate you may need more insulation include:

  • Energy bills that are higher than normal
  • Walls and floors that are unusually cold in the winter
  • Snow melting off your roof too quickly and/or ice dams forming in the winter
  • An uncomfortably warm second story
  • AC running more than normal in the summer

Whatever your case, it’s a good idea to talk to a local insulation company.

For specifics—including the type of attic you have, how much insulation is already installed and more—it’s best to talk to insulation professionals. Generally speaking, however, it’s important to insulate attic floors, knee walls, etc.

Attics are commonly insulated with loose-fill/blown-in cellulose and fiberglass insulation. To truly maximize energy efficiency, it’s important to also seal gaps, ducts, the attic hatch and any other space that is prone to air leaks.
