So what's this R-value I've been hearing so much about?
R-values are a way of measuring the thickness and effectiveness of
insulation materials. Different geographic regions and different-aged
homes vary in the amount of insulation they need. R-values help you
determine what type of insulation is best for your situation.
 In
The Oak Ridge National Laboratory has created an online computer program
that will help you determine the R-value most appropriate for your
home. It will ask you a whole slew of questions, and will make very
specific recommendations based on the way you answer. You can access
the program for free online.
Proper insulation will not only keep you comfortable-it can reduce
your home heating and cooling costs by up to 30%. Once you have determined
what R-value you need, start putting that knowledge to work. If you
can't insulate or re-insulate your entire home at once, consider getting
the work done bit by bit. You should start by insulating your attic,
including the attic door or hatch cover. Then work your way around
to the exterior walls, basement walls, floors and crawl spaces. By
investing just a few hundred dollars, you could reduce your heating
bills dramatically.
