Phoenix home window company explains Low-E windows

Jason Mariner, owner of a Phoenix home window company called Clear Cut Glass, explains the benefits of Low-E windows.

Low-E windows are simply low-emissivity windows. Low-emissivity refers to a low heat emissivity meaning that it prevents the transfer of heat from one side of the window to the other. Low-E windows are windows that have a coating on them to give them this property.

In Arizona, because the goal is to keep heat out, a metallic coating is applied in a thin film to the inside pane of an insulated unit on a home’s windows. The film can be applied in several layers depending on need and because they are applied to the window and not bonded to it like in a window tint, Low-E windows look uniform to the eye.

Low-E windows work by filtering out the types of light. There are three types of light that interact with a Low-E window. The first type is infrared light or heat and these types of light wavelengths Low-E windows prevent these from permeating through the window. UV, or ultra-violet light is the light that gives sunburns or fades furniture. Low-E windows filter this type of light as well. The last light is visible light, or the light we see, and these rays are allowed to penetrate Low-E windows’ metallic film.

Because they reduce the heat absorbed in the home, Low-E windows save consumers money by reducing the amount of money spent on cooling their houses. They also reduce fading in home décor, furniture and floors, which can save money over time as well. Low-E windows are a great affordable option for Arizonians looking to protect their home from the heat and save money on their energy bill.
