Low emissivity coatings, or Low-E coatings, consist of a fine silver mist sprayed on the interior side of the exterior pane of insulated glass. The coating reflects room-side infrared energy back into the room. The better the glazing is at reflecting these waves, the lower the U-value. The U-value assigned to an insulated glass unit indicates the amount of heat transmitted through the glazing material.
All Windsor products utilize Cardinal’s LoE glass, which has been setting the standard for energy efficiency for the past 20 years. These products offer high transparency, low reflectivity and excellent thermal insulation, all of which combine to provide energy-saving benefits to the homeowner.
LoE 366 is Windsor’s standard glazing. This provides the ideal balance of solar control and high visibility for the highest levels of year-round comfort and energy savings.
