How To Remove The Internal Glass Of A Low-E Storm Window?

Low-E glass storm windows are designed to reduce air leakage, provide increased insulation, and reduce ultraviolet light entering your home. These windows are made from multiple pieces of glass with a special coating applied to the innermost layer of glass. To remove the glass on a low-e window, use light pressure and be careful not to cut into the glass. Remove the sashes (aka screens) from the inside by sliding them upward. Most sashes have small latches that must be pulled and held inward before you can slide up and tilt these out of place.

Removing the glass on a low-e window is a relatively simple process that can be done with a few basic tools and the right knowledge. Low-E coatings applied to exterior window panes prevent heat gains from exterior radiation, while coatings applied to interior windows help prevent heat loss. Manufacturers usually offer several types of Low-E coatings.

On a national average, ENERGY STAR certified (low-e) storm windows can save homeowners $350 on their annual heating and cooling bills when installed over single-pane clear glass. Low-E storm windows can reduce noise, reflect radiant heat 35 better than clear glass storm windows, act as an air sealing measure, and reduce overall home air leakage by 10 or more.

To install a low-e storm window, follow these steps: use light pressure, be careful not to cut into the glass, remove the sashes from the inside by sliding them upward, and caulk the top and sides of the existing window opening. Low-E storm windows are a good option for improving energy efficiency, being less expensive than replacement windows and allowing homeowners to keep their existing windows clean.
