Energy Efficient
Our standard high-performance Low-E insulating glass lowers energy costs, helps homes stay cooler in the summer and warmer in the winter, reducing the fading of interior furnishings and condensation. It also delivers greater visible light transmittance than tinted glass.
Optional Low-E EC is recommended for homes located at altitudes above 4,000 feet and requiring more energy efficiency than our standard Low-E glass. This glass features a second coating of Low-E on the interior side of the glass which provides dual protection to help retain even more heat inside the home. We also offer optional Lodz-366 glass, which provides more protection against heat gain by blocking harmful infrared rays, as well as providing greater energy savings.
All three glass options are available with argon gas, which helps reduce conduction and consequent energy loss, and high-altitude* glass. This option prevents glass panes from bowing in higher elevations. It includes breather tubes (placed between the panes of insulating glass) to equalize the airspace pressure with the atmosphere.
With Low-E, Low-E EC or Lodz-366 glass, ENERGY STAR® qualified versions of this product are likely available. This means they meet or exceed the minimum energy efficiency criteria for your climate region. For more information, ask your dealer how to order JELD-WEN ENERGY STAR qualified products specific to your area.
*High-altitude glass is not available with argon.
