The Energy Efficiency Myth

A common argument for replacing historical windows is energy savings. However, data from organizations like the National Trust for Historic Preservation recommends that a well-kept historic window coupled with a high-quality storm window can attain thermal efficiency nearly equal to a brand-new double-pane window.
