When it comes to attic insulation, how much is enough? For most modern homes, the average is around R-25. But if you have an older home, you may not have anywhere near that.
It really comes down to comfort and cost. If you are cold and uncomfortable, than more than R-25 would be good for you. If you can add more insulation to your attic and earn a return on your money, than you may want to add more as well.
Your attic insulation accounts for a lot of your heating bill. So contact me and I can help you make the right determination.
