How to Insulate Your Basement Ceiling How to Insulate Your Basement Ceiling

As a homeowner with a house in an area of the country with extreme temperature ranges, you will need to insulate your basement ceilings if you expect to reduce energy consumption and costs. But before you buy your insulation and begin installing it you will need to know something about your choices of insulation and how to install it.

Things you'll need:

  • Staple gun
  • Ladder
  • Protective goggles
  • Wallpaper scissors
  • Insulation Foam Sprayer

Step 1 – Inspect Your Ceiling

Depending on whether or your basement ceiling is finished or whether your ceiling joists are still exposed, this will influence your decision as to which type of insulation you can use. If your ceiling is finished, your choices will likely be limited to spray foam or loose fill. For unfinished ceilings use fiberglass batts, rigid foam, or spray foam.

Step 2 – Installing Fiberglass Batts

For a ceiling where you're installing fiberglass batts, place a batt into the space between two joists, paper side facing down. Use your staple gun to attach these strips to the sides of your joists.

Step 3 – Installing Spray Foam

When installing spray foam insulation, use a spray applicator and spray the foam into the spaces between your joists. Be sure the foam doesn't extend below the lower edge of joists that are exposed.
