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

A common criticism of Victorian sash windows is that they are "cold and draughty." However, modern-day remediation strategies have actually solved these concerns without compromising the window's appearance.
Draught-Proofing: Specialized brush strips can be routed into the meeting rails and staff beads. This eliminates rattles and lowers heat loss by up to 30%.Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed systems into existing timber sashes. These systems have an extremely thin profile (frequently 12mm total density) and fill the gap with Krypton or Xenon gas to supply insulation similar to modern-day 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 installed.
