Vitro America is a leading provider of insulating glass used for high-quality residential and commercial windows. Insulating glass consists of two or more hermetically sealed glass panes separated by an air space in combination with various sealants, spacers, gases and desiccants. It is designed to reduce heat loss in cold weather and solar heat buildup during warm weather, and to filter out unwanted noise. Insulating glass can be made with the amount of space between the panes determining energy performance and acoustical benefits.
