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.
Low-E glass offers many benefits for replacement windows, including that it:
- Is not visible, so it will not impede or darken the view out of your windows
- Is more effective at reflecting infrared heat than traditional window tinting and glazing options
- Provides energy-efficient qualities all of the time, as opposed to shades and shutters that only block the heat when the shades are closed and the entire view is blocked
- Can also help block damaging UV rays from entering through your windows, keeping your carpeting and furniture from fading or deteriorating prematurely
- Can also help reduce glare on your TV screen and other shiny surfaces by blocking UV and infrared rays
- Contributes to less strain on the HVAC system, which can help reduce monthly energy bills and reduce your carbon footprint
- Can be used in conjunction with other great window features, such as enhanced security features, so it’s not an either-or decision
