I'm having an Energy Star home built. Why would I need foam?

The Energy Star program is sponsored by the U.S. government and its intent is to give incentives to builders to exceed the minimum necessary energy requirements for a new home. Although the program has resulted in more energy efficient homes, it is a relatively easy hurdle to reach. The program allows fiberglass insulation to be used, which is ironic because Fiberglass is literally the least efficient insulation permitted by code — and the US Government has concluded that it is a likely carcinogen. Every bag of fiberglass sold in America is labeled with a cancer warning. In short, an Energy Star home using foam insulation will be 30%-50% more efficient for heating and cooling than a fiberglass insulated Energy Star home.
