On recent episode of PowerHouse you said ice dams were caused by insufficient insulation and air sealing in the attic. Could you please tell me more about air sealing?
Have a Home Performance with ENERGY STAR evaluation.
Here are two links to web sites that do a good job of describing air sealing and the importance of doing it prior to adding insulation, especially in attics.
1. Background information on air sealing
2. Air-seal and Insulate with ENERGY STAR®
The most thorough and reliable way to determine your home's air leakage and identify where the leaks are is to have a home evaluation completed through the Home Performance with ENERGY STAR® program. Find a consultant in your area and get started today!
