Windows add light to your home, but they can also be a source of energy loss if they’re drafty, outdated, fit poorly or contain single-paned glass. If you notice drafts coming from window areas, or your window frames are cracked or damaged, they may not be performing as they should and costing you energy dollars. Even multi-paned glass windows may not be working properly if the glass has condensation or appears cloudy.

How Should Windows Perform?

Windows are designed to allow light in and provide views to the outside. Glass by itself is not a good insulator, so modern windows have developed technological innovations to improve their energy performance. Some of these advances include:

  • Double- or Triple-Pane Construction

The thermal performance of windows can be enhanced by employing two or three layers of glass, often separated by a layer of inert gas and sealed tightly within the frames.

  • Low-e Coatings

These energy-efficient coatings can reflect radiant heat while untreated glass allows that energy to dissipate through into the home.

  • Solar Heat Gain

In the winter, windows on the south side of your home can collect the sun’s energy and provide free heating to those rooms.

  • Well-Sealed Frames

Energy efficient rated windows also ensure that the frames are well constructed of materials with recommended R-values and sealing to keep air from seeping into the house.

  • Proper Installation

Upgraded windows should be professionally installed so that the wall areas around the openings are sealed with foam and securely attached to the wall frame.
