• Package Frame: The hollow frame that houses the weights.
• Weights and Pulleys: Lead or iron weights linked by Sliding Sash Window Specialists cables over a pulley wheel, allowing the window to stay open at any height.

The Restoration Process Explained

An expert restoration is a systematic process designed to return the window to its initial magnificence while improving its efficiency.

Step 4: Draught-Proofing

This is perhaps the most substantial functional upgrade. Discrete brush seals are machined into the staff beads, parting beads, and the conference rails. This gets rid of rattles and lowers heat loss by as much as 80%.

Step 5: Priming and Painting

The wood is treated with a preservative, primed, and completed with premium microporous paint, which enables the wood to "breathe" while supplying a weather-resistant barrier.

• Exercise the Windows: Open and close the sashes at least once a month (even in winter season) to prevent them from taking.
