henever possible, double channel frames that accommodate both the stained glass windows and their protective glazing should be used. Their use facilitates the installation, and any future removals, of either glass panel without affecting the other. We recommend the frames of the J. Sussman Company.
esthetically, these frames are preferential as well, since retrofitted “storefront” frames become wider with the necessary framing add-ons. This increased visual mass is more intrusive on the stained glass design than the double channel frames. It is also more expensive to retrofit “storefronts” than to use the double channel frames from the beginning.
