This equates to $100–$300 in annual savings, assuming a $1,000 annual heating/cooling bill.

On average, low-e storm windows can save you 10%–30% in heating and cooling costs.

This coating improves the window’s insulation ability, in turn lowering your heating and cooling costs. In fact, installing a low-emissivity (low-e) storm window over a single pane window can lower your utility bill just as much as replacing the window with a new energy code-level window.Ĭoated with an ultra-thin, virtually invisible layer of metal, low-e windows reflect infrared heat back into the home. They’re easy to install and cost a fraction of replacement windows. Storm window installation is one of the most cost-effective solutions for upgrading energy inefficient existing windows.
