By the late Victorian duration, "plate glass" became the standard for high-end builds.Weights and Pulleys: The sliding mechanism depends on a system of lead or cast-iron weights suspended by cotton sash cords over brass wheels. This counterbalancing system enables even the heaviest windows to be opened with minimal effort.The Importance of Maintenance

This gets rid of rattles and lowers 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 systems have a really thin profile (often 12mm total density) and fill the gap with Krypton or Xenon gas to supply insulation equivalent to modern windows.Secondary Glazing: For Grade I or II listed structures where the glass can not be altered, a discreet internal glass secondary pane can be installed.
