Low-E and LoE –3-366 insulating glass


Our standard Low-E insulating glass lowers energy costs, helps homes keep a comfortable temperature year round, prevents fading of interior furnishings, and reduces condensation. It also delivers greater visible light transmittance than tinted glass. We also offer optional LoE –3-366, for increased heat gain protection and greater energy savings.

Dual Low-E insulating glass

This option is recommended for homes located at altitudes above 4,000 feet and requiring more energy efficiency than our standard Low-E glass.

Windows containing any one of JELD -WEN’s insulating glass options are energy s tar® qualified, which means they exceed the minimum energy efficiency criteria for the climate region you live in (by as much as 40 percent).

• Tempered glass: This optional glass provides extra strength

• Neat glass: Gain all the energy efficiency of Low-E with this glass option, along with natural cleaning convenience

• High-altitude insulating glass: This option prevents glass panes from bowing in higher elevations
