Low E Windows for Impressive Energy Efficiency

Option – Low E Windows

Low E (Low Emissivity) is the term used to describe the amount energy that transfers through materials. When referring to energy transfer through windows, the IR (infrared) and UV (ultraviolet) light or energy that allows heat transfer and fabrics and objects to fade is minimized and the visible light spectrum is maximized. In windows, a low e coating is applied to flat glass during a special manufacturing process. At Ringer Windows, we offer 3 different types of Low E windows, all specifically suited for Texas.

Low E glass contains two to three layers of silver nitrate (depending on which type is used) that are molecularly bonded to the glass.  Low E glass is slightly darker than clear glass, but not by much. The Low E coating is micro-thin, never peels, and is nearly invisible. Its powerful component drives efficiency in all our replacement windows and new construction windows.

In summer, it’s what keeps the heat out during the summer months and inside during the winter.

The “Ins and Outs” of Low E Windows

Sunlight is primarily composed of 3 components, Ultraviolet Rays (UV), Infrared Rays (IR), and the Visible Spectrum of light. The visible spectrum of light is desirable and harmless. The ultraviolet spectrum causes fading and discoloration to interior furnishings and paint. The infrared spectrum is what heats-up interior surfaces, flooring, and fabrics, causing your home’s interior temperature to rise. Infrared is the “hot” component that we aim to keep out!

The superior low E glass in Ringer Windows blocks most of the harmful UV and infrared spectrums while allowing most of the good visible (desirable) light to pass. We’ve dubbed this glass, “spectrally smart” because it stops most of the bad stuff and allows just the good stuff to pass!

Ringer Windows Glass Options for
Low E Windows

We offer several types of Low E glass options, starting with our basic Low-E 270 and our spectrally smart Super Low-E 366. Our 270 blocks 86% of UV and Infrared while our Super Low-E 366 stops a phenomenal 95% of the harmful infrared and UV light, making it the most efficient Low-E glass we’ve ever seen! For those that seek a much darker look or serious glare control, LoE3 340 is our darkest Low E glass option.
