Nevertheless, the Victorian era brought two significant changes: the abolition of the Glass Tax in 1845 and the advancement of glass manufacturing technology. These elements enabled designers to move far from small, multi-paned windows toward larger, much heavier panes of glass.

By the late Victorian duration, "plate glass" became the requirement for high-end builds.Weights and Pulleys: The Sliding Sash Window Installers system relies on a system of lead or cast-iron weights suspended by cotton sash cords over brass wheels. This counterbalancing system allows even the heaviest windows to be opened with very little effort.The Importance of Maintenance

This removes rattles and minimizes heat loss by approximately 30%.Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed systems into existing lumber sashes. These systems have a very thin profile (frequently 12mm total density) and fill the gap with Krypton or Xenon gas to supply insulation comparable to modern-day windows.Secondary Glazing: For Grade I or II listed buildings where the glass can not be altered, a discreet internal glass secondary pane can be set up.
