By the late Victorian period, "plate glass" became the requirement for high-end builds.Weights and Pulleys: The sliding system relies on a system of lead or cast-iron weights suspended by cotton sash cables over brass pulleys. This counterbalancing system permits even the heaviest windows to be opened with minimal effort.The Importance of Maintenance

This removes rattles and reduces heat loss by as much as 30%.Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed systems into existing wood sashes. These units have an extremely thin profile (frequently 12mm total thickness) and fill the space with Krypton or Xenon gas to provide insulation similar to contemporary windows.Secondary Glazing: For Grade I or II listed buildings where the glass can not be changed, a discreet internal glass secondary pane can be set up.
