We are so pleased with the Climate Seal interior storm windows we installed in the Moody Museum. They have done exactly what we needed them to do. They have blocked air leakage, humidity and heat as well as dust that was a constant problem with the original windows in our museum. Our museum is located in a Victorian home built in 1887 and the original windows needed to be preserved but were no longer sufficient for the purpose of preserving the contents of our historic building.
