Replacement Windows
Modern replacement windows made of gas-filled Low-E glass can increase the warmth of your windows threefold over your existing windows. However, this option will cost you somewhere between $300 to $500 or more per window. The cost of replacing existing windows often requires the owner to take out a second mortgage to pay for the bill and it might take decades to break even on the return of the investment in energy savings. For example, replacing windows on an average home with 12 windows will cost $3,600 to $6,000 or more and some estimates might run up to $10,000 or more depending on the type of windows selected. Obviously replacing windows on a larger home with many more windows is an expensive proposition!
