Spray foam insulation, if installed properly, can make a dramatic difference to your utility costs. Getting a reliable estimate of the kind of savings you may realize is not so easy though. This is because there are many factors that will affect your overall savings. Also, while we tend to talk a lot about heat loss, it should be noted that in warmer climates, loss of cooler air or warming of a home through radiant heat, are just as relevant and costs can be reduced just as effectively as heat loss is in colder climates by applying spray foam insulation. For structures with existing walls that need to be insulated, there is also the option of injection foam insulation, a process very similar to spraying, where the foam is injected into walls without removing the drywall, which uses the same foam as that which is sprayed, and has the same cost savings.
Factors That Affect Cost Savings with Foam Insulation
- What areas in your home or office is the foam insulation being applied to?
- These may include ceilings, roofs, attic spaces, all or selected exterior walls, internal walls, basement areas, under flooring.
- The type of foam insulation, open cell or closed cell?
- The general construction of your building.
- Properties vary a lot in the extent to which they are draft proof. Note, depending on where it is applied, foam insulation aids in significantly reducing drafts. The type of windows installed can make a big difference to drafts and general heat loss or heat gain.
- Use of the building.
- Frequently accessed buildings or rooms, doors left open etc. all make a big difference to the loss of the internal environment.
- The type of heating or cooling system installed.
- This can make a big difference, HVAC systems vary a lot in power and efficiency and are sometimes miss-sized for the building they are installed in.
- The temperature of choice.
- Some people prefer cooler or warmer environments than others.
- The local environment.
- Different parts of the States experience very different temperatures than others. That coupled with general weather trends, wind speed, humidity and rain all naturally make big impacts on the internal environments in any building.
- What are you comparing your new spray or injection foam insulation to?
- What was the previous form of insulation installed and how well was it installed? Are you applying spray foam insulation to areas where there was no insulation or poor/partial insulation?
Spray and Injection Foam Insulation, 30% – 40% Utility Cost Savings – Rule of Thumb
In general, when comparing foam insulation as a replacement solution to typically installed forms of insulation you can expect to see about a 30% – 40% reduction in utility costs. This may vary by about plus or minus 10%, depending on the above factors. For example, a very drafty house with poor seals will not experience as great a savings as a home with modern doors and windows with good seals.
Therefore the greater the temperature difference maintained in the building, compared to outside conditions, then the greater the impact foam insulation may have on cost savings.
Average residential home heating and cooling costs vary greatly around the U.S. Annual estimates range between $1,000 to $2,500. Our rule-of-thumb calculation is that we’re going to assume an annual HVAC utility cost of $1,850. This does not include such things as furnace repair and maintenance costs. If we apply a 35% savings, we are looking at a potential annual saving of $648. Based on that, we project a break even or return on investment at between 5 to 7 years.
This means that for an “average” householder that invests in foam insulation, they can expect to recoup their investment in about 6 years. After that it is realistic to project that they may be saving $648 a year in reduced utility bills.
