What is low e argon gas?
Low-E glass is manufactured by depositing a microscopically thin, transparent metal or metallic oxide layer on the glass. Low-E coatings reduce radiant heat loss, and can reduce the passage of UV rays. Use of heat-resistant (or absorbing) glass began in the 1950s, as did the use of reflective (or mirror) glass. This type of glass cuts the loss of heat during the winter and the absorption of sun in the summer. This provides year round savings by lowering your energy bill.
