Low-e glass, or low emissivity glass, is a type of energy-efficient glass that is designed to reduce the amount of heat that is transferred through windows. It works by reflecting infrared and UV light, while allowing visible light to pass through.
Infrared, or heat, is able to reach the low-e coating on the glass but is then reflected back towards its source. This helps to keep the heat inside during cold weather and outside during hot weather, resulting in lower energy costs for heating and cooling.
Yes, some infrared light is able to pass through low-e glass. The amount that is able to pass through depends on the type of low-e coating and the thickness of the glass. However, the majority of infrared is reflected back, making low-e glass more energy-efficient.
Low-e glass is safe to use for windows and is commonly used in residential and commercial buildings. It does not emit any harmful substances and is designed to improve energy efficiency and comfort.
Using low-e glass for windows has several benefits, including improved energy efficiency, reduced energy costs, and improved comfort by reducing heat transfer. It also helps to block UV light, which can fade furniture and flooring over time. Additionally, low-e glass can help to reduce outside noise and make a building more soundproof.
