However, the Victorian period brought two significant modifications: the abolition of the Glass Tax in 1845 and the development of glass production innovation.

Victorian houses often featured thick masonry walls. Sash windows were typically held up from the outer face of the brickwork into a "reveal." This safeguarded the wood from the elements. The mechanism itself-- the weights and pulley-blocks-- was hidden inside a hollow lumber box frame constructed into the wall.
3. Ornate Architraves and Surrounds

Products and Construction
The durability of original Victorian Sash Window Refurbishment Company windows is a testimony to the quality of materials utilized in the 19th century.
Timber: Most original windows were constructed from slow-grown softwoods, such as Baltic Redwood, or hardwoods like Oak and Teak for more affluent homes.

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

A typical criticism of Victorian sash windows is that they are "cold and draughty." Nevertheless, modern-day remediation techniques have actually resolved these issues without compromising the window's look.
Draught-Proofing: Specialized brush strips can be routed into the meeting rails and staff beads. This eliminates rattles and reduces heat loss by up to 30%.Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed units into existing timber sashes. These units have a really thin profile (typically 12mm overall density) and fill the space with Krypton or Xenon gas to supply insulation equivalent to contemporary windows.Secondary Glazing: For Grade I or II noted structures where the glass can not be changed, a discreet internal glass secondary pane can be set up.
