Moderate Cost; High-Performance; Moderate ER Number.
Low-E Glass is double glazed and Argon gas filled, which helps to reduce heat loss, in winter, to the cold outdoors by dramatically reducing radiant heat transfer and actually reflecting interior heat back into the room.
It allows more of the sun’s rays to enter a home as solar energy to be converted into usable heat. In the summer, it helps to reduce the flow of hot outside air into the cooler interior. Therefore, it helps to lower your energy cost all year long. Low-E Glass also reduces transmission of the sun’s UV ray which is the leading cause of premature fading and degradation of fabrics and carpeting.
