What is the cost of spray foam insulation?

How much does spray foam insulation cost?

“You get what you pay for” is perhaps never truer than when it comes to insulating your home or business. Spray polyurethane foam has been called the “miracle insulation” for a reason. While the upfront spray foam insulation cost may be a bit more than that of other products, when properly installed by a skilled and knowledgeable professional, it can net you unbeatable savings and comfort for years to come.

The cost of open cell and closed cell spray foam

Spray foam comes in two forms: open cell and closed cell. According to homeadvisor.com, open-cell spray foam cost ranges between $0.44 and $0.65 per board foot, while closed cell spray foam comes in at $0.70 to $1 per board foot. The average cost to have spray foam professionally installed is about $1,795.

Spray foam cost variables

Cost, of course, can vary depending upon a number of factors, including whether the home being insulated is newly constructed. With a newly constructed home, installation is often simplified since the insulation contractor may be able to coordinate with the architectural crew in a manner that offsets costs. Accessing all areas that need to be sprayed may be more difficult and time-consuming in existing homes.

Initial insulation investments are offset by long-term savings

Some industry professionals indicate that the initial cost of installing spray polyurethane foam is two to three times the cost of more traditional insulation forms such as cellulose or fiberglass batts. However, homeadvisor.com asserts that it also insulates homes at least 50% more than traditional products. In short, spray foam insulation offers a number of benefits that make it an appealing option despite the higher initial investment that it requires:

  • Increased energy efficiency
  • Reduced energy costs
  • Reduced noise
  • Improved structural strength
  • Resistance to moisture, mold, and mildew resistance
  • Resistance to settling, deterioration and decomposition over time
  • Suitability for a number of locations in your home/building (attics, crawlspaces, basements, walls, ceilings, windows, garages, foundations, around HVAC pipes, condensers, floor registers and ductwork; around plumbing pipes and outdoor faucets, etc.)
