The Add On Glass system was developed in Europe forty years ago. The system was introduced to the United States in 1980 and has been installed to hundreds of thousands of windows in the past twenty years. The Add On Glass system creates a double insulated glass unit without removing the original glass or window frame. The Add On Glass system provides all the benefits of a factory made thermo-pane window at an incredible price. In addition to a great value the Add On Glass system is installed in such a way that that commercial and residential building owners are not inconvenienced during the installation of the system. The system is installed to the original glass in a clean and quiet manner that does not disturb the homeowner or business where the work is being performed.
Experience and history have shown that conversion of single-pane window glass to double-insulated thermal glass can greatly reduce heating and cooling costs. The average installation can pay for itself in just five years.
