What is the cost vs. other insulation mediums?
Typically SPF insulation cost between 3 and 4 times the cost of fiberglass batt, cellulose and blown-in insulations. Pay back is typically 4-5 years if only the 30% to 40% energy cost savings are considered, but there are other cost savings to be considered. ECO-THERM SPF insulation being impervious to moisture, eliminates the need for additional moisture barriers and building wraps. The per inch R-value of 6.5 will yield a total 2×4 built wall R-value of 25.5, to achieve an equal R-value with other insulation mediums would require 2×6 built walls increasing building costs 30%. Sealing the building envelope and eliminating exterior air infiltration will allow for the engineered down sizing of the HVAC system. The builder will qualify for an IRS energy efficient tax credit. www.resnet.us/taxcredits www.energystar.
