- "Insulation is SEXY stuff" that was the message President Obama was sending to Congress today! Obama is pushing for incentives to make homes more energy efficient to help Americans reduce their utility bills! It’s interesting that in 1973 the payback was 12-18 months to get your money back by adding insulation to your attic.....today it’s less because of the artificial equation...added stimulus rebates...now 40% ROI sounds great and remember once you get the initial payback..it last forever...not bad...beats anything else I could find to invest in????
