Old, drafty windows don’t get the final say. NES offers some easy fixes to improve the efficiency of your windows without having to spend a lot of money to replace them.
You can increase the comfort level of your home by sealing air leaks and investing in better insulation to stop air loss around your windows. Follow these five simple steps to help lower your energy bill.
STEP 1: PREPARE EXISTING WINDOWS
Check each existing window to ensure there is no missing glass, rotting wood or broken parts. If there are obvious leaks around the frame of the window, use caulk or weather stripping to stop the air loss.
STEP 2: INSTALL HIGH EFFICIENCY STORM WINDOWS
If your primary windows are in fairly good condition, attaching low-e storm windows can boost energy efficiency at about a quarter of the cost of a total replacement. Storm windows reduce air infiltration, whether they are coated or not. However, low-e coating, a nearly invisible layer on the glass, can improve overall energy savings 10-15 percent more than standard storm windows.
STEP 3: ORDERING LOW-E STORM WINDOWS
Typically, storm windows should be custom ordered to fit your existing windows. They are available at both independent window dealers and big-box retailers.
STEP 4: REBATES FOR ADDING STORM WINDOWS
NES offers rebates of up to $250 through eScore for purchasing and installing storm windows to single pane windows. Check out the incentives at nespower.com/escore.html.
STEP 5: KEEP STORM WINDOWS UP ALL YEAR
Modern storm windows can be left in place year-round, with sashes and insect screens that can be opened in the summer.
If storm windows aren’t an option, try applying heat shrink film, which looks like a thicker version of plastic wrap. Sheets of the film can be cut to size and attached to the inside of the window frame with double-sided tape. Use a hair dryer to shrink the film to provide a better seal around the window.
