Double silver Low-E glass is a kind of top grade Low-E glass. The glass underlines the shielding effect to the solar energy; the high visible light transmittance performance and low transmission performance of solar heat are skillfully combined. In addition to the features of Low-E glass listed in the foregoing, it also provides the following special features:
Higher visible light transmittance: ensuring the excellent natural lighting
Very low solar heat gain: effectively warding off the solar energy
While maintaining the same visible light transmittance, it has lower shading coefficient. The double silver Low-E glass is more suitable to the climatic features of California with far better comprehensive energy saving effect. The production of double silver Low-E glass requires the production line with over 24 cathodes.

Warm-edge technology Visit www.warmedge.com for more information
"Warm-Edge" spacer system for I.G. units creates an effective thermal barrier to help reduce thermal conductivity. Lower U-Values and improve higher insulation performance.
“Warm-Light” by Azon USA is a combination of aluminum and polyurethane designed to provide numbers improvements over conventional aluminum spacer or stainless steel spacer.
Double Low-E + “Warm Light” Spacer
The I.G. units of Double Low-E with “Warm-Light” spacer result in a high performance, highly structural, thermally improved, warmer glass temperature, eliminates condensation and saves energy in any climactic condition.
