Low-E Glass in Double Glazing: Right for Your Home?


In recent years, the superior insulating power of Low-E glass in double glazing has become increasingly popular due to its numerous benefits. Let's delve into the details…

Low-E glass, or low-emissivity glass, is a type of glass treated with an invisible metallic oxide coating designed to significantly reduce the amount of heat, ultraviolet (UV), and infrared light that can enter your home. This innovative coating enhances the thermal insulation performance of double-glazed windows, providing a comfortable and energy-efficient living space.

What Is Low-E Glass?

Low-E glass owes its effectiveness to a special coating that allows the sun’s rays to pass through while reflecting indoor heat back into the room. This significantly reduces the amount of heat, UV, and infrared light entering your home.

Double glazing involves using two panes of glass with a gap in between, filled with air or a special gas like Argon. This insulation gap not only helps retain heat but also reduces outdoor noise, such as traffic. Combining Low-E glass with double glazing results in windows with superior insulation properties, leading to a more energy-efficient home, lower energy bills, and a comfortable living environment.

Energy Efficiency and Comfort Benefits of Low-E Glass

Heat Insulation

Low-E glass significantly improves the energy efficiency of double-glazed windows by controlling infrared light, perceived as heat. By reflecting heat back into a building during cold months and keeping solar heat at bay in warmer seasons, this microscopic coating reduces UV and infrared light penetration. Combined with the insulation provided by double-pane windows, this ensures superior thermal performance.

Reduced Energy Consumption

For homeowners looking to cut their heating bills, Low-E glass and double glazing can work together to reduce energy consumption. Enhanced thermal insulation means less reliance on heating systems in winter and air conditioning in summer. Energy-efficient glazing prevents heat from escaping through windows, improving a building’s overall energy efficiency. This translates to a more comfortable indoor environment and lower energy bills.

Noise Reduction

In addition to temperature regulation and lower energy bills, Low-E glass in double glazing contributes to noise reduction within a property. The low-emissivity coating and the gap between glass panes absorb and minimize external noise transmission. This feature is particularly beneficial in urban areas where traffic noise and other disturbances can impact tranquility and well-being.

Low-E Glass = Lower Carbon Emissions

One significant benefit of Low-E glass in double glazing is its ability to lower carbon emissions. By reflecting heat back into the room, Low-E glass reduces the need for additional heating, thus lowering energy consumption and resulting in lower carbon emissions from buildings. It also allows natural heat and light to enter the building, further reducing the need for artificial heating and lighting.


Sustainability is a priority for many homeowners and businesses. Low-E glass in double glazing promotes sustainable building practices. It blocks more than 90% of UV rays, preventing damage to furniture, flooring, and window treatments. This contributes to a more comfortable and healthier indoor environment, reducing drafts and cold spots, and creating a stable interior temperature.

Low-E Glass = Reduced Heating & Cooling Bills

Low-E glass is an excellent choice for improving your home's energy efficiency. Installing windows with Low-E glass in energy-efficient double or triple glazed units can significantly lower heating and cooling bills, saving you money. Low-E glass can reduce energy use by up to 30-50%, particularly during the hot summer months.


Many homeowners worry about the durability of Low-E glass. Soft-coat Low-E glass is durable and can be cleaned confidently since the coating is sealed between the glass layers, ensuring it cannot be wiped off or scratched. This makes it a long-lasting, cost-effective, and energy-efficient option for your home.

In conclusion, Low-E glass in double glazing offers numerous advantages in terms of comfort, energy efficiency, and sustainability. Its ability to regulate indoor temperatures, reduce noise, and lower energy bills makes it an ideal choice for modern homes.
