Glass Coatings

Energy Efficient LoE Coatings

  • Notes:
    Lo E coatings exhibit certain color characteristics depending on viewing angles, reflected light and time of day. For example, Cardinal LoE 366 exhibits a greenish hue. When Clear glass is coupled with a LoE 366 coating, during certain times of the day the reflected color can appear green from the outside. This LoE 366 coating offers an excellent combination of thermal performance, visible light transmittance, and value. 
    When heat strengthened glass is used, roller wave distortion is an inherent possibility.
