What are Low-E (Low-Emissivity) coatings?
Low-E (Low-Emissivity) coating is a thermal performance coating applied to the inside glass face to reflect long wave radiation and restrict heat transfer, thus improving the glass U-value. It is transparent when applied to float glass and iridescent on channel glass. Bendheim’s Lamberts channel glass with Low-E coating has an approximate U-value of 0.41.
