Low E Glass

Low-e Glass for Replacement Windows in The Finger Lakes

Low-e energy efficient window installation in NY

The label doesn't lie. Every replacement window unit should come with a detailed NFRC (National Fenestration Registration Council) label. The Solar Heat Gain Coefficient will tell you how effective the low-e coating is at blocking unwanted heat gain in summer and reflecting indoor heat in winter.

We use the best glass to promote energy efficiency in New York

Most of us have heard about "low-e glass," which is used in both new and replacement windows. Low-e technology has been used on windows since the mid-1970s, and every major window and door manufacturer offers low-e glass on their products.

If you're in the market for replacement windows or exterior doors that contain insulated glass, it's smart to get up to speed on how low-emissivity films work, what the difference is between "hard-coat" and "soft-coat" versions, and how to make sure your new glass qualifies for different rebate programs.

Let's get started with the benefits of low-e glass:

  • Improved energy efficiency. This is a big deal, since windows can be responsible for 25% of a home's wintertime heat loss. In addition to reducing heat loss during winter months, low-e glass also reduces heat gain during the cooling season.
  • Less UV damage. By blocking most ultraviolet (UV) radiation, low-e glass helps protect fabrics, leather, carpeting, artwork and finishes from the fading effects of sunlight.
  • Reduced condensation. Condensation on window glass can be a problem during the heating season, as warm air comes into contact with cold window glass and gives up its moisture, forming water droplets on the glass surface. Low-e glass will minimize or eliminate this unwanted condensation.
  • Rebates on windows & doors. If you install new or replacement windows and/or doors that are ENERGY STARĀ® qualified (which include low-e glass), you may be eligible for a tax credit. Halco can provide you with the most up-to-date information on tax credits for energy-saving home improvements.

How low-e glass works

The "e" in low-e stands for emissivity - the ability to emit radiant energy. A dark asphalt driveway has a high e-factor; it will absorb and emit a great deal of heat. A low-e coating emits almost no radiant energy. The coating is actually an invisible metal or metallic oxide film that's deposited on the surface of the glass during or after the manufacturing process. This microscopic layer allows light (short-wave energy) to penetrate the glass, but blocks most ultraviolet (UV) long-wave energy, which we feel as heat. Here's how low-e windows improve energy efficiency during summer and winter months:

  • Winter mode. Light is admitted through the glass, but heat from interior spaces is reflected back into the house interior by the low-e coating.
  • Summer mode. Light is admitted through the glass, but heat from outside is reflected, helping to reduce cooling costs.
