Single glazed old sash windows are notoriously less energy efficient than new ones. While new double-glazed windows will save on energy bills in the long run but less effective when it comes to noise reduction. Replacing old sash windows in a period property may actually decrease the value of the house. So when it comes to upgrading old windows, the homeowner has to be careful and consider all the options available.
