We would like to thank you for supplying Climate Seal Window Inserts. We have been installing these inserts over the past five years in our 90-year old Shaker Heights French Normandy home. Every window is composed of leaded glass as shown in the photograph; the living room window alone has 135 panes of glass. While these old windows are beautiful, they certainly let in lots of drafts and provide minimal insulation.
The Climate Seal Inserts not only provide a barrier against the cold outside air, but they minimize the outside noise. Installation is not difficult and maintenance is very simple. Most importantly, they do not detract from the beauty of the original windows. We will continue to use this product and tell our friends about it.
