Energy Efficiency: Can Old Windows Perform?
A common argument for replacement is that old windows leakage energy. While single-pane glass is a bad thermal insulator, windows are just part of the thermal envelope.
Studies conducted by the National Trust for Historic Preservation have actually revealed that a brought back historical window coupled with a quality wood or aluminum storm window carries out comparably to a new double-pane replacement window. Storm windows create an important dead-air space that significantly cuts down on heat transfer, while still enabling the historic interior window to stay noticeable and functional.
