Image of Insulating Glass Certification Council's mascotThe Insulating Glass Certification Council (IGCC) is a non-profit organization jointly established in 1977 by manufacturers, consumers, specifiers, and others concerned with the quality and performance of insulating glass units.

IGCC sponsors and directs an independent true third-party certification program. Periodic Accelerated Laboratory tests by the American Society for Testing and Materials (ASTM) specifications, and unannounced plant quality audits and inspections, assure the quality and performance of sealed insulating glass products.

Trust the industry watchdog to maintain tough standards for insulating glass!

Low E Windows

  • Increase the value of your home.
  • Reduce the noise level in your home.
  • Block UV Rays that fade the interior fabrics on your furniture.
  • All options can be provided in tempered and anneled glass.

Low-emittance (Low-E) coatings are microscopically thin, virtually invisible, metal or metallic oxide layers deposited on a window or skylight glazing surface primarily to reduce the U-factor by suppressing radiative heat flow. The principal mechanism of heat transfer in multilayer glazing is thermal radiation from a warm pane of glass to a cooler pane. Coating a glass surface with a low-emittance material and facing that coating into the gap between the glass layers blocks a significant amount of this radiant heat transfer, thus lowering the total heat flow through the window. Low-E coatings are transparent to visible light. Different types of Low-E coatings have been designed to allow for high solar gain, moderate solar gain, or low solar gain.
