SIPs Cost and ROI

Real-World Savings

One Thermocore customer had an Energy Star Home Evaluation. His home was 3,573 square feet, and is located near Green Bay, Wisconsin. The report showed an annual energy savings of $3,265 or $272 per month versus a traditional stick-frame house. That's money in your pocket every month that you can't get from traditional stick framing.

The panels paid for themselves entirely in 10 years.
