Signa Insulating Glass installation which provides all the benefits of hermetically sealed double glazed windows including drastic sound reduction. General Information What is Signa System? The SIGNA SYSTEM is an insulating glass unit created out of your existing single glazed window by adding and hermetically sealing an additional layer of glass by means of a special, patented air spacer. The spacer contains a moisture absorbing desiccant, which will keep your insulated glass free of moisture and condensation. The dead air space between the two llayers of glass will keep you warm in the winter and insulated from heat in the summer. This process has been developed in Denmark, by the founder and president of SIGNA SYSTEM, Inc. Ryszard Borys, and has been in commercial use since 1976.
