In this tutorial, we learn how to insulate your attic with Eric Johnston. To figure out if you have enough insulation, you need to measure the depth of the insulation that you have. Generally, you should have around 22" of insulation in attics. The highest percentage of energy loss is through the attic, even if it's a new home. You can use a blown in insulation system that is easy to install and will not cause a huge mess. With this, you will be able to have your home be much warmed and you will be saving a lot of money on your energy bill!
