Do impact windows save energy?

Additionally, impact windows block 99% of transmitted UV light, which can be especially helpful to energy bills in the sunshine state. Impact windows can help Florida residents save approximately 40% on cooling costs. Additionally, the stronger framing materials used with impact windows also provide superior draft protection.

If you're seeking optimal energy savings, talk to your provider about glass with lower U-factor (measure of heat transfer) and Solar Heat Gain Coefficient, or SHGC, (how effectively the window blocks solar heat). The lower the U-factor and SHGC ratings, the more energy efficient a window is.
