If you are a long-time Windows on Washington reader, you will know we talk a lot about insulation. Why? Because good insulation is perhaps one of the most important components of an energy-efficient and comfortable home. As a quick recap, insulation works to inhibit the transfer of heat. In the winter, it prevents cold air from the outdoors from penetrating the interior of a house, helping to keep the home warmer inside. During the summer, insulation helps trap cool, conditioned air inside the home while resisting heat from the outdoors. Essentially, it helps improve the comfort of your home by maintaining a constant indoor temperature, while reducing the frequency and duration of your air conditioning unit (good for the wallet and environment!)
