However, the Victorian age brought 2 significant changes: the abolition of the Glass Tax in 1845 and the improvement of glass manufacturing innovation. These factors allowed architects to move away from small, multi-paned windows toward larger, heavier panes of glass.

By the late Victorian period, "plate glass" became the standard 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 sheaves. This counterbalancing system allows even the heaviest windows to be opened with very little effort.The Importance of Maintenance

This removes rattles and lowers heat loss by approximately 30%.Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed units into existing lumber sashes. These units have a really thin profile (typically 12mm overall density) and fill the space with Krypton or Xenon gas to offer insulation comparable to modern windows.Secondary Glazing: For Grade I or II noted buildings where the glass can not be changed, a discreet internal glass secondary pane can be set up.
