Feeling Chilly? Make Sure You Insulate These Important AreasCan you feel a draft in your home? Maybe it’s only cold in one spot, or maybe there are several rooms in your home that are significantly warmer or colder than the thermostat’s set temperature. This might happen for a number of reasons, but the culprit is often insufficient insulation. Here are some areas that are critical to insulate for optimal home comfort and efficiency.


Your attic must be well-ventilated for consistent fresh airflow, so it’s one of the most important areas to properly insulate. Add fiberglass bats or loose-fill insulation over the entire floor of your attic and seal air leaks to cut down on thermal exchange with the living areas below.

Exterior Walls

Exterior walls are the first major barrier between your home and the elements outdoors. You should insulate exterior walls by:

  • Having dense-pack insulation blown into empty cavities.
  • Adding protective sheathing before adding new siding.
  • Adding spray foam during major home renovations that open up the wall cavity.

Spray foam and blown-in insulation should both be installed by an insulation professional to prevent damage caused by overfilling and to ensure the best possible thermal barrier.


If you’re building a new home, insulating the foundation will head off a lot of potential problems. It’s easier to heat and cool a home with an insulated foundation, which also provides a barrier between your home and the ground.

This barrier can help reduce moisture, prevent radon infiltration and keep pests out. For existing homes, talk to an insulation contractor about the options and benefits of insulating basements and crawlspaces.


Floors are frequently the most overlooked areas when it comes to insulation, but they can exchange a lot of heat. If your floor is always cold, especially if it’s over an unheated garage or unfinished space, then it’s time to add some insulation.
