How much does spray foam insulation cost?

Though there are many types of insulation on the market, spray foam insulation has become the standard type for thermal insulation in many homes. You may be wondering how much does spray foam insulation cost. Several factors influence the price such as:

  • insulation type (open or closed cell)
  • labor costs
  • size of the area to be spray foamed
  • the brand
  • geographic location
  • your home
    contractor’s rates.

It’s no surprise that spray foam has become one of the top insulation types on the market. This kind of insulation not only helps maintain your home’s temperature and assists you in creating your ideal indoor space, but it also helps you to save money on heating and cooling bills. The amount you save on monthly heating and cooling bills will help pay for the cost of the insulation over time.

Of course, cheaper DIY options, such as blown-in cellulose fiber or fiberglass batts are available. These options, however, will not seal cracks and gaps to prevent air leaks, like XCELUS spray foam will do, and they will likely deteriorate over time. 

New Homes

It’s best to install spray foam insulation when your home is new or under construction for easy access to all areas of the home, including the walls. When your whole home is insulated with XCELUS spray foam, you’ll realize monthly savings of as much as 40% on heating and cooling bills, when your HVAC is right-sized. The thermal barrier will protect against cold and hot spots, sounds from outside and room to room will be reduced, and the built-in moisture barrier will help to prevent mold.

Existing Homes

The most cost-efficient places to insulate an existing home with spray foam are attics and bonus rooms.

The purpose of attic insulation is to prevent airflow from inside to outside, and from outside to inside. This flow of air is called a ‘stack effect’. Airflow consumes a tremendous amount of energy. Over time traditional types of insulation, such as fiberglass, may degrade and no longer stop this airflow. When that time comes, spray foam insulation is the best solution.

Rooms over garages, or bonus rooms, are often under insulated. In cold climates, floors can be as much as 10°F cooler than the room. In warm climates, summer heat makes them unbearable. Spray foam insulation helps keep the temperature even, throughout the seasons creating a more comfortable room


After noticing a lack of understanding, passion, and knowledge of the market, we developed XCELUS out of our passion to create better living conditions for our communities.
