Step 3: Re-cording and Balancing
Old cords are changed with modern, wax-coated cotton cords with a polyester core for added strength. The weights are examined to ensure they perfectly counter-balance the weight of the sashes (particularly important if brand-new, thicker glass has been set up).
Step 4: Draught-Proofing
A contemporary draught-proofing system is generally integrated during the repair. This includes machining small grooves into the beads and sashes to house brush strips. These strips close the spaces, getting rid of rattles and substantially lowering heat loss.
Step 5: Glass and Putty Work
Broken panes are changed with period-appropriate glass (such as crown glass or slim-profile double glazing), and the putty lines are restored to provide a weather-tight seal.
Improving Energy Efficiency While Preserving History
Among the most persistent misconceptions is that sash windows need to be changed to make a home "warm." In reality, a brought back and draught-proofed sash window can equal the thermal efficiency of lots of modern windows.

Approaches to increase efficiency include:
Draught Excluders: Professional brush seals can minimize air infiltration by as much as 80%.Slim-Profile Double Glazing: Specialized double-glazed units are now available that are thin enough (as low as 11mm) to suit original sash frames without altering their look.Secondary Glazing: An internal glass pane can be added, which is typically the preferred option for Grade I or Grade II listed structures where the original material can not be modified.Maintenance Tips for Long-Lasting Sash Windows
