What Are Low-E Glass Windows

Krasiva Windows and Doors in Phoenix recognizes that one of the main concerns of homeowners searching for window and door replacement services near Greenway High School is maximizing energy efficiency, so this is the main factor behind the high demand for Low-E glass windows among homeowners in this locality. Should I consider getting Low-E glass windows? Do they indeed get the job done? Kasia expounds on the interest and gives responses to top inquiries.

What is Low-E Glass? 

The abbreviation of Low-E stands for Low Emittance or Low Emissivity. It is used in the replacement of doors as well as windows to decrease the exchange of internal & external temperatures. Low-E Glass offers an energy-efficient solution.

A reflective layer is added on top of the glass surface as an application for redirecting heat back to its source since energy-conscious individuals looking to lower their energy use can benefit from using a metallic oxide coating since it allows light to pass through while reflecting unwanted heat away thereby decreasing their utility bill expenses.

Brief History of Low-E Glass

Low-E glass was created during the 1980s with one major goal—to minimize window heat loss, and the first version of Low-E glass had only one layer coated on one side. But later versions have improved efficiency by adding more layers, and Low-E Glass’s popularity has recently increased among individuals looking to reduce their environmental impact by increasing building’s energy efficiency.

Importance of Low-E Glass for Arizona Homes

Arizona’s famous hot & dry weather encompasses lengthy summers and comfortable winter months, so an ideal spot for Low-E glass window installation is here, as it can greatly decrease the quantity of heat entering your house in summer. In warm areas like Arizona, research shows that Low-E glass can lower cooling costs by as much as 25% and, besides this, by reflecting heat back into your home during winter months, Low-E glass helps in maintaining a warm environment inside, which ultimately leads to significant cost savings by reducing heating expenses.

By installing Low-E glass windows in your home, you can benefit from energy savings and protection from the damaging effects of UV radiation on furniture and artwork. Low-E Glass can increase privacy and security levels by obstructing outsiders’ views.

Given that hot temperatures are an all-year-round concern in Arizona, it’s imperative that homeowners pay close attention, and by reflecting radiant heat outside via windows and doors, Low-E glass helps to reduce the amount of indoor heating. Achieving greater home comfort at a lower cost is possible by following this approach.

Are Low-E Glass Windows and Doors Worth it?

When considering window and door replacement, one of the most common questions is whether Low-E glass is worth the investment. Not only are Low-E windows comparatively priced, but they also pay for themselves in savings. According to Energy.gov, between 25-30 percent of heating and cooling use is due to heat loss or gain through glass windows and doors. When calculating heating and cooling costs, it is easy to see why Low-E glass is a huge advantage. 

What are the Types of Low-E Glass?

The two primary kinds of Low-E glass are passive and solar control, whereas passive Low-E glass reflects heat back inside the house instead of letting it escape outside, which makes it ideal for colder regions with high heating expenses. Solar control Low-E glass can help homeowners in warmer climates save on cooling costs since it is specifically designed to reflect heat away from a room while still allowing natural light into the building.

Solar heat gain coefficient (SHGC) is lower in Passive Low-E Glass that makes it possible for less solar heat to enter buildings, unlike Solar Control low E-Glass, so if you live in an area with frigid temperatures and want to reduce your heating expenses using passive Low-E glass can help. While limiting sunlight infiltration may be possible with some glasses, such as low-e-glass with no solar control, Solar Control Low-E Glass allows for better penetration of sun rays. Hence, the use of Low-E glass to control solar heat gain makes it a suitable option for warmer climates where reducing cooling costs is important.

Hard coats and soft coats are the two main types of Low-E glass coatings, and the addition of a coating on Hard coat Low-E glass happens in its manufacturing process. The trade-off for increased durability and scratch resistance is lessened energy efficiency when compared with soft-coat low-E glass.

Following its manufacture, a layer is added onto the glass surface of the soft coat Low-E, and the energy efficiency of the coating is improved. However, the susceptibility of glass to scratches and damages has increased. Pairing Soft coat Low-E glass with laminated or tempered often enhances the overall safety and durability of the final product.

How is Low-E Glass Made?

The application of metallic oxide onto the surface of the glass results in Low-E glass, typically applying a sputter coating method employing either silver or tin oxide as materials to form a layer for the surface finish.

The glass undergoes sputtering by exposing it to an electrical charge fired from a metallic oxide target in a vacuum chamber, so the result is that they become ejected from their starting point as atoms of metallic oxide make their journey across a vacuum chamber prior to reaching its end destination on top of the glass—bonding between metallic oxide atoms and the surface of glass results in the formation of a thin coating.

Once the coating has been applied, the glass is typically tempered or laminated to increase its strength and durability. Tempered glass is heated to a high temperature and then rapidly cooled, which causes the glass to become stronger and more resistant to breakage. Laminated glass is made by sandwiching a layer of plastic between two layers of glass, which provides increased strength and safety.

After the glass has been tempered or laminated, it is cut to size for custom window and door replacement. Low-E glass is typically used in double or triple-pane windows to provide increased energy efficiency and reduce heat transfer through the glass.

What Does Low-E Glass Do?

The low-emissivity (Low-E) coating on the surface of Low-E glass is a thin, transparent layer of metal or metal oxide. This coating reflects heat back to its source, which reduces the amount of heat that is transferred through the glass. The Low-E coating works by reflecting the heat back to the source in one of two ways:

  • Reflecting short-wave infrared energy (heat) back outside during hot summer months.
  • Reflecting long-wave infrared energy (heat) back inside during cold winter months.

The amount of heat that is reflected depends on the type of Low-E glass and the orientation of the glass. For example, a solar control Low-E glass will reflect more heat than a passive Low-E glass.

How Low-E Glass Reduces Heat Loss and Gain

By reflecting infrared sunlight instead of allowing it to travel through a window pane, Low-E glass effectively preserves energy, and a transfer of heat takes place through infrared radiation, where the energy radiated as electromagnetic waves by a hot surface gets absorbed by a cooler surface. In winter, using Low-E glass windows redirects warmth from outside toward your home’s interior, thus promoting comfort by reducing your reliance on heating systems. Low-E glass operates effectively throughout the year by reducing reliance on air conditioning during hot weather and heating systems when it’s cold outside. A substantial reduction in electricity usage could reduce expenses related to utility services.

What Are the Top Benefits of Low-E Glass?

When paired with efficient frames and components, Low-E glass offers a range of benefits for homeowners and builders, including:

  • Energy Efficiency: Low-E glass reduces heat loss and gains through windows and doors, which can lead to significant energy savings.
  • Comfort: Low-E glass can help to maintain a more consistent indoor temperature, which can improve comfort levels in the home.
  • UV Protection: Some types of Low-E glass also provide protection against UV radiation, which can help to prevent furniture, carpets, and other items from fading over time.
  • Improved Home Value: Installing Low-E glass windows and doors can increase the value of a home and make it more attractive to potential buyers.

Differences Between Low-E Glass and Standard Glass

Low-E glass differs from standard glass in several ways. Standard glass has a high level of emissivity, which means it absorbs and emits a large amount of radiant heat. This can lead to significant heat loss and gain through windows and doors, increasing energy costs and decreasing comfort levels in the home.

In contrast, Low-E glass features a reduced transfer of heat due to its special layer of coating. This coating reflects heat back to its source, decreasing the amount that passes through the glass. This can lead to lower electricity expenses, enhanced comfort levels, and more effective safeguarding against damaging UV rays.

In comparison to standard glass, Low-E glass is less effective in passing through light, transmitting approximately 70-80%, whereas standard glass is successful in passing through 90% of visible light. The lack of luminosity is a result of the Low-E finish, which curbs the amount of visible light that gets through the window. Nevertheless, picking a better grade Low-E glass or adding extra windows and doors can balance out the depletion in visible light transmission.

Advantages of Low-E Glass Over Standard Glass

There are several advantages of Low-E glass over standard glass, including:

  • Energy Efficiency: Low-E glass is significantly more energy-efficient than standard glass, as it reduces heat loss and gains through windows and doors. This can lead to lower energy costs and improved comfort levels in the home.
  • Comfort: Low-E glass can help maintain a more consistent indoor temperature, improving comfort levels in the home. This is particularly important in areas with extreme temperatures, such as Arizona.
  • UV Protection: Some types of Low-E glass provide protection against harmful UV radiation, which can help to prevent furniture, carpets, and other items from fading over time.
  • Improved Home Value: Installing Low-E glass windows and doors can increase the value of a home and make it more attractive to potential buyers.
  • Customizable Options: Low-E glass is available in a range of customizable options, including different insulation levels, solar control, and visible light transmission. This allows homeowners and builders to choose the best option for their specific needs and preferences.

How Custom Windows Differ from Stock Windows

Stock window frames are offered in standard measurements and designs, often making them less costly compared to custom windows. They can usually be found in home improvement shops. Nonetheless, stock windows may not align properly in all homes and may not offer equivalent levels of energy efficiency, comfort, and aesthetic appeal as custom windows.

Alternatively, custom windows are crafted and assembled to fit the exact specifications of a home. This might mean using exclusive materials, non-standard sizes, and shapes, or specific features like reinforced insulation or noise reduction. Custom windows can promise a better alignment, more efficient energy efficiency, and increased aesthetic appeal compared to stock windows.

If you live in Arizona, installing custom windows featuring Low-E glass is the best way to ensure your home has optimal energy efficiency and comfort while protecting against UV radiation. Custom windows can also be designed to take advantage of natural light and ventilation, improving air quality and reducing energy costs.
