Windows are wonderful! Or at least they should be. But there's a great deal more to enjoying wonderful windows the just keeping them crystal clearly clean. Windows let in a lot more than sunlight. They allow heat and cold transfer and are prone to minor drafts. Multiply this by the size and number of windows in most homes, and it can have a serious impact on energy efficiency. Any opening in the exterior of your home can increase your utility bills by as much as 15 percent! So it's important to weatherize whenever and wherever you can. Windows are a great place to start!
