Coated heat-insulating glasses

Abstract

Coated heat-insulating glasses were developed after the first energy crisis at the beginning of the seventies. With these glasses heat insulation in the window area has been improved essentially. A review will be given on the construction and on the mode of action of these glasses, containing as central element of function a highly transparent coating on the base of tin oxide or a layer system on the base of silver. In the meantime the latter coating has succeeded worldwide because of its better technical values. The manufacture and the difficulties with the processing of this coating are dealt with. Coated heat-insulating glasses with metal filter layer systems on the basis of silver are compatible with today's sheet glass technology and have proved to be reliable as glazing for 8 years.
