Frequently Asked Questions
What is the difference between open cell and closed cell foam?
Open cell foam is a softer, less dense foam closed cell, and has an R-value of approximately 3.5 per inch of thickness. Closed cell is a hard rigid foam that can be used as a vapor barrier and has an R-value of approximately 7 per inch of thickness.
How much energy would spray foam save me in an existing home by retrofitting it into the roofdeck?
We have seen an average of 40% reduction in home energy usage over the hundreds of retrofit houses we have done. Results can vary based on additional structures, pools, etcs.
What is the average payback time on a new home if I use sprayfoam instead of fiberglass insulation?
Depending on which foam you use, the average payback due to the vast reduction in electrical usage is usually from 3 to 4 years.
Are there other benefits to using polyurethane spray foam besides just its ability to super insulate?
Absolutely! Spray foam does not contribute to any dust in a house, fiberglass degrades over time and can contribute to dust problems in an older home. Sprayfoam can also make a house much stronger when the closed cell version is used. Likewise, as energy efficiency of homes becomes more of an issue, the use of spray foam in a house can greatly add the value of the home.
Does the use of spray foam in a new home affect the tonnage of air conditioning and heating needed in that home?
Yes, since the house is much tighter and has less air infiltration, the tonnage of heating and air conditioning in a home can be decreased by as much as 40% depending on the structure. We can give you even run a Manual J Load Calculation on the house to better address your needs.
