How Low-E Glass Keeps You Cooler in Summer

Heat naturally flows from hot objects to cool objects, which is why an ice cube melts on a hot day, rather than becoming colder. During the summer, this spontaneous process can have a dramatic effect on the indoor temperature of your home as heat moves through glass into the cooler interior. Unwanted heat gain can happen in two ways: by sunlight shining directly on the windows, and when heat is radiated by your driveway, sidewalk, plants and other surfaces into your home.

The Power of Low-E Coatings

Low-Emissivity (Low-E) coatings are one of the newest innovations in window performance. On a sunny day, windows with untreated glass let in heat energy and make it difficult to control indoor temperatures and utility costs. Metallic Low-E coatings applied to the glass surface reflect outside heat and light from the sun, yet are so microthin you can still see through the window clearly! The reflective power of Low-E glass is important in climates where solar heat gain is a primary concern.
