- Package Frame: The outer frame that houses the sashes and the internal sliding system.
- Sash Cords and Weights: In standard windows, lead or iron weights hidden in the frame balance the sash via a cord and pulley-block.
- Spring Balances: A contemporary alternative to weights, utilizing a tensioned spring to hold the sash in place.
- Sash Horns: Decorative protrusions on the bottom of the upper sash, initially developed to strengthen the joints in much heavier Victorian glass.

- Spring Balance: These utilize a pressurized spring hidden within a slimmer frame. They are normally more cost-efficient and enable bigger glass areas since the "box" frame does not need to be as broad to accommodate weights.
Maintenance Checklist for Longevity
To make sure sash windows remain in leading condition, a regular maintenance schedule is needed, especially for timber options.
Yearly Maintenance Tasks:
- Cleaning: Wash the glass and frames with mild soapy water.

- Cable Inspection: For conventional windows, inspect the sash cords for fraying to prevent the weights from dropping.
Expense Considerations
The cost of sash windows varies based on the intricacy of the installation and the products utilized. Custom-shaped windows (such as arched tops) or specific heritage requirements will increase the investment.
