Definitions for "Low-Emissivity glass"
A coated glass to reduce heat transfer by reflecting electromagnetic waves.
Glass with a transparent metallic oxide coating applied onto or into a glass surface. The coating allows short-wave energy to pass through but reflects long-wave infrared energy, which improves the U-value.
Glass which restricts the passage of radiant heat, in and out; a metal or metal oxide coating applied to the glass to provide low emissivity.
