Today’s Tip from The Green Year: 365 Small Things You Can Do to Make a Big Difference: Winterize your windows.
You don’t have to replace your windows to take advantage of the latest energy-saving technology. Plastic film with low-E coating, an invisible layer of metallic oxide, helps reduce heat loss through old windows by up to 40 percent.
Home improvement stores sell low-E film for $3 to $12 per square foot. The self-adhesive film helps trap heat indoors during the winter. In less than one year, you’ll save enough on your utility bills to cover the cost of low-E coating.
