#RuleYourAttic: Check Your Results

Rule Your Attic for comfort and savings

In the second installation of the Rule Your Attic! series, we’ll check the results of your insulation measurement and learn what the numbers really mean.

For commonly used blown (loose-fill) fiberglass, mineral wool, or cellulose insulation (assuming an R-value of about R-3 per inch):

  1. If you live in a Northern State and have less than 16-18 inches of insulation you are below the recommended levels.
  2. If you live in a Southern State and have less than 12-14 inches of insulation you are below the recommended levels.
Map that indicates northern and southern states regarding insulation levels

In the map above, zones 4-8 are considered Northern, zones 1-3 are Southern.

Now, if your levels are good, relax and have a cup of hot cider. If you are below the recommended levels, don’t sweat it. It’s not too late to make an improvement and lower your annual energy bills by up to 10% by sealing air leaks and adding insulation to your home.

From now through November 20, post a picture or short video of your attic floor insulation using the hashtag #RuleYourAttic

The next question is: should you do it yourself or hire a contractor? Check back in a few weeks – or check out the links below – and we will help you Rule Your Attic for comfort and savings!
