As you know, we think historic windows are really important. Historic windows are the eyes of a building. The size of the pane, the profile of the muntin, and the joinery provide clues to date windows, tell a building’s history, and are an important part of the beauty of historic buildings. Yet, historic windows are disappearing at an alarming rate, often because property owners think they can only get energy savings with replacement windows.
We understand that owners of historic properties often struggle with energy efficiency issues. In the past few months we have become familiar with a Vermont-made product that will help save energy.
EcoSmart shades from Gordon’s Window Decor have been tested and have received a rating of an R-4+, so that the combination of a weatherized historic window, a good quality storm window, and an EcoSmart shade will yield in the range of R5.5+. Clearly this is a significant improvement over a storm window and historic window combination as well as an improvement over thermo-pane replacement windows which generally yield an R value of R2.5-R3. Unlike replacement windows, the combination of storm, historic window, and an EcoSmart shade offers the potential for harvesting solar gain during the day.
