WHAT IS LOW-E?
Low-E (Low emissivity) is a microscopic transparent coating of metallic oxides that are applied to a glass pane. Low-E glass helps reduce the amount of infrared and ultraviolet light that flows through your windows. Natural light still comes through the windows, unimpeded, so you never notice a difference in the aesthetic value of all that light. Low-E coating protects your furniture, floor and carpets from fading and helps protect you from the harmful UV rays. It also helps reflect the interior temperatures back into your home, instead of letting the warm air flow out through the window. It keeps your house warmer in the winter and cooler in the summer.
How it works?
The glass is coated with a microscopically thin, optically transparent layer of silver sandwiched between layers of anti-reflective metal oxide coatings. A protective coating is applied to assure durability and long life. The coating is virtually invisible to the eye – it’s just like looking through clear glass. Low-E coating is virtually clear, blocking the heat and reducing solar gain while optimizing light transmission. This helps to reduce electrical loads while protecting interior furnishings from UV damage.
The vast portfolio of energy-efficient glass options includes one, two and three layers of performance to keep rooms comfortable, views glare- free and energy bills manageable for homeowners in any weather.
BENEFITS OF LOW-E COATING
The purpose of LoE coatings is to minimize the amount of heat that can pass through the glass while allowing visible light to transmit through. These coatings work by reflecting a significant portion of infrared (heat) radiation, which helps keep the interior of a building cooler in hot weather and warmer in cold weather.
The specific characteristics of LoE coatings can vary depending on the manufacturer and product, but generally, they offer the following benefits:
-

Improved Insulation
LoE coatings reduce heat transfer through the glass, which helps maintain a more consistent and comfortable indoor temperature. This can result in energy savings by reducing the need for heating and cooling.
-

Solar Control
LoE coatings can also help control the amount of solar energy that enters a building. By reflecting a portion of the sun’s heat, they can help minimize the impact of direct sunlight on interior temperatures and reduce the need for air conditioning.

UV Protection
Many LoE coatings also offer ultraviolet (UV) protection by blocking a significant portion of harmful UV rays. This helps protect interior furnishings, such as carpets, drapes, and furniture, from fading and sun damage.

Enhanced Light Transmission
While reducing heat transfer, LoE coatings are designed to maintain high levels of visible light transmission. This allows natural light to enter the building, reducing the reliance on artificial lighting and creating a more pleasant indoor environment.

Reduced Energy Demand
By minimizing heat transfer through windows, LoE coatings reduce the demand for heating and cooling systems. This leads to lower energy consumption and associated costs, promoting energy efficiency and environmental sustainability.
GLASS OPTIONS FOR WINDOWS
It’s important to note that there are different types and variations of LoE coatings available, each with its specific characteristics and performance metrics. When selecting windows or glass products with LoE coatings, consider factors such as the climate in your region, desired energy efficiency, and aesthetic preferences.
Consulting with our professionals specializing in energy-efficient windows can provide further guidance on the best LoE glass options for your specific needs.

LOÉ 180
When the weather turns frigid, LoĒ-180™ glass is the perfect cold remedy. It keeps homes warm and comfortable by blocking heat loss to the outside and letting the sun’s heat stream in. With a glass U-Factor of just 0.26 and an SHGC of 0.69, LoĒ-180 is the ideal product for passive solar applications.
Features:
- LoĒ-180 delivers outstanding cold weather performance – its insulation value is excellent with a low 0.26 U-Factor. With an SHGC of 0.69, it lets the winter sun’s heat pass into the home
- It blocks 71 percent of the sun’s harmful UV rays. While blocking out the cold and UV rays, it lets the daylight stream in – more light than ordinary low-e glass.
- Summer solar gain is about 10% less than ordinary double or triple pane clear glass and the low U-Factor blocks heat gain from the hot weather outside.
Recommend for:
- Cold weather climates
- North facing windows
