Secret Architectural Features of Victorian Sash Windows

• Glass: Early Victorian glass was "cylinder glass," which often has slight ripples or imperfections. By the late Victorian period, "plate glass" became the standard for high-end builds.
• Weights and Pulleys: The Sliding Sash Window Specialists mechanism relies on a system of lead or cast-iron weights suspended by cotton sash cords over brass sheaves. This counterbalancing system permits even the heaviest windows to be opened with minimal effort.

The Importance of Maintenance

Because these windows are made of natural materials, they require constant care to endure another century. Neglect is the main cause of sash window failure, causing rot, rattling, and draughts.

List: Essential Maintenance Tasks for Victorian Sash Windows

• Cill Inspection: The bottom cill is the most susceptible part of the window as it bears the force of rainwater. Guarantee it is clear of particles and well-painted.

1. Draught-Proofing: Specialized brush strips can be routed into the meeting rails and staff beads. This gets rid of rattles and reduces heat loss by as much as 30%.
2. Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed units into existing timber sashes. These systems have an extremely thin profile (often 12mm overall thickness) and fill the space with Krypton or Xenon gas to supply insulation comparable to modern windows.
3. 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.
