• Weight and Pulley: This is the authentic method used for centuries. It involves a cable, a pulley wheel, and a lead/iron weight. It is preferred for Grade II noted buildings because it allows for the conventional deep "box" appearance.
• Spring Balance: These use a pressurized spring hidden within a slimmer frame. They are usually more economical and permit for bigger glass areas because the "box" frame does not require to be as broad to accommodate weights.

Maintenance Checklist for Longevity

To ensure sash windows stay in top condition, a regular maintenance schedule is required, especially for timber options.

Annual Maintenance Tasks:

3. Visual Inspection: Check for signs of flaking paint or wood rot, especially on the sill (the bottom-most part).
