Storm doors can increase energy efficiency by 45 percent. By sealing drafts and reducing air infiltration, storm doors decrease the heat loss that tends to occur around this opening of the house. Storm doors also offer options for light and ventilation and come in a variety of attractive designs. They are built to last long and offer reliable protection against the elements.
Energy Star labeled storm doors must meet specific U-value and shading coefficient ratings for at least one U.S. region. The products are tested by the National Fenestration Ratings Council (NFRC). Consumers are eligible for a tax credit of 10 percent of the cost of the door, or up to $500. In order to qualify for the tax credit, consumers must install the door in combination with a wood door assigned a default U-factor by the International Energy Conservation Code (IECC). In order to collect your credit, be sure to save your receipt and Manufacturer’s Certification Statement, which ensures that the product you purchased is qualified. Many manufacturers, such as Larson Storm Doors, provide this documentation on their website.
Energy efficient doors typically have multiple glass panes to reduce heat flow, a tighter fit and improved weather stripping to reduce air leakage, and improved core materials such as fiberglass, wood cladding, or steel with polyurethane. Home envelope Energy Star products are available at Ace Hardware, The Home Depot, Lowes, Sam’s Club, Sears, Staples, and Wal-Mart. Manufacturers of Energy Star labeled storm doors include Larson and Gorell.
