Thought I'd post an update on the radiant barrier. Our last electric bill was about $82. which I think is pretty good for a 1400 sf. home. We've been keeping the house at about 75* inside. I think the radiant barrier is well worth the money I spent. Where I was living in NC last year I was only cooling about 1000 sf. and the electric bill was running about $100.-$120. per month and the house wasn't as cool as where we are living now. I've also noticed that the a/c doesn't usually run for extended lengths of time. Since the 1st day of this month we have used about 400kwh and there have been a couple days where the heat index was between 110*-120*. I think our power bill for May when we didn't use the a/c at all was about $45. so the actual cost of cooling the house was less than $40. last month. I'd definitely recommend radiant barrier to anyone who's considering building a new home or just wants to make improvements to help on heating and cooling costs.
