4 Ways to Improve Window Energy Efficiency

Posted on Updated on

To improve performance of existing windows, consider storm windows, window films, and exterior roller shades before buying replacement windows.

Below are four ways to help improve window energy efficiency:

1. Replacement windows–  full window replacement, insert windows (the old sashes come out and a whole new window inserts into your old window frame), and sash replacement (primarily for double-hung windows, this option requires jamb liners into which new sashes are installed).

2. Low-e storm windows- airtight storm windows with low-e coatings can rival the performance of just about any window replacement.  And now you can buy low-e storms with high solar heat gain for colder climates and low solar heat gain for warmer ones.

3. Window films can be temporary or permanent– There are two primary types of window films: more permanent, surface-applied films and the stretch-plastic that you install temporarily to interior window trim.

4. Exterior roller shades keep the sun out– If keeping the heat out is your main concern, the most effective window treatment options are exterior; you keep the sun out before it gets in
