Home Energy Efficiency
While new dual pane windows offer great curb appeal they do little for home energy efficiency. The Federal Trade Commission has warned or filed charges against more than a dozen window companies to ensure their marketing is truthful. Some companies were claiming up to a 50% return on investment thanks to energy savings. You are more likely to realize a 3% return sense a window is a hole basically. The place to start to get a return on investment, in relation to energy savings, would be investing in insulation. Insulation generally cost less than half of what windows would cost.
