Adding Insulation to Our Attic


I received a $10 off $50 coupon at Lowes Home Improvement with my Discover Card in the mail this week. These are a great excuse to start a home improvement project and I can see why Lowes finds it profitable to send this out.

After some thought I decided it was a perfect time to pick up $50 of insulation with the coupon and add some additional insulation in the attic of our house. After looking at the options I decided to go with 5 rolls of R30 fiberglass insulation as it was actually cheaper than the R19 for the same coverage. $9.97 for 31.25 sq feet of R30 which I believe is down from ~$15.87 last year.

I was able to roll out the insulation within 20 minutes and strategically applied it to areas where I suspect we have the greatest heat loss in our attic - a cathedral ceiling and the ceiling area of our 2-story foyer.

If I can just save $5/year in energy costs from this additional insulation I feel like I'm making a decent (10%+) rate of return on this investment. Add on top of that the 10% Federal Energy efficient tax credit and while I won't be able to actually measure the results, I do feel comfortable I'm getting a decent return on this investment, despite it being small change.

Am I crazy to think I can already tell a difference? I can't help but notice the temperature on our thermostat is staying higher through the night despite the HVAC being turned off.
