Low-E Glass Windows for Impressive Energy Efficiency

Option – Low-E Glass 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 low-e glass is the controlling component in energy efficient Low-E Glass Windows. IR (infrared light) is the heat energy. UV (ultraviolet) light is the unwanted energy that fades fabrics and paint. Low-E glass windows filter unwanted IR and UV light. Visible light is maximized. The Low-E coatings are applied to flat glass during a special manufacturing process.

NEW! Double Pane Low-E Glass with Triple Pane Efficiency!

Enhanced 366!

At Ringer Windows, we offer 4 different types of Low-E glass windows, all specifically suited for Texas. Low E glass Windows have two to three silver nitrate layers that are molecularly bonded to the glass providing a permanent coating. . The LoE-i89 glass has three silver nitrate layers and an Indium layer for the ultimate low-e glass protection. Low-E glass windows have a slightly lower visible transmittance than clear glass, but provides outstanding energy efficiency in your windows. The Low-E coating is micro-thin, never peels, and is nearly invisible. Its powerful component drives energy efficiency in all our replacement windows and new construction windows.

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

The “Ins and Outs” of Low-E Glass 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 during the summer, but keep in during the winter!

Superior Ringer low-E glass windows block 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!

Options for Low-E Glass Windows

Ringer Windows offer several types of Low-E glass windows.
The basic two-coat Low-E 270 blocks 86% of UV and Infrared. while our he spectrally smart triple coat, Super Low-E 366 Low-E 366 stops an impressive 95% of the harmful infrared and UV light. The Low-E i89 takes the Low-E 366 triple coat glass and adds an additional reflective Indium coating on the room side glass surface to reflect heat back inside during cold weather. The i-89 is the most efficient Low-E glass we’ve ever seen! For those that seek a much darker look or serious glare control, Low-E 240 is our darkest Low E glass option.
