Special Glass calls for special protection. We have a number of storm window models and a variety of special materials which can provide different levels of protection for these valuable windows. Large undivided panels are available, as well as special shapes. It is very important to provide venting for stained or leaded glass, to relieve the heat which builds up between the windows. We use a variety of venting methods, including spacers, reticulated foam tape that breathes, and special screened vents.
