Installing ENERGY STAR certified windows will not only reduce your energy bill by an average of 12% per year, but it will also stop cold air from leaking out in the summer and keep heat in during the winter. ENERGY STAR windows increase your home’s comfort year-round and can even reduce UV sun damage to floors, drapes, sentimental photographs and furniture.
Energy-efficient windows are created by putting sheets of glass together with spacers. These multi-layers have air pockets between the panes, which are sealed shut and prevent air from entering or escaping. Once this is complete, the windows are filled with argon, krypton, and other gases, all of which are non-toxic, odorless, and colorless to increase their efficiency.

Windows in new and old homes are candidates for replacement. Older homes built before the 1980’s usually have single-paned wood windows, which are very inefficient. These windows decrease the overall comfort of your home and increase your energy bills due to air leaks from cracks or disintegrating putty. Even if your home is only 15-25 years old, new windows might be worth the investment. You should at least be making repairs regularly, which might include adding insulation, fixing drafts, or repairing cracks in the frames, but you will need to replace the entire unit eventually. If your home has vinyl or aluminum windows, these can’t be repaired or restored, because they are all one piece. You will need to update these types of windows entirely.
