- Package Frame: The outer frame that houses the sashes and the internal sliding system.
- Sash Cords and Weights: In conventional windows, lead or iron weights concealed in the frame balance the sash through a cable and pulley-block.
- Spring Balances: A modern-day option to weights, utilizing a tensioned spring to hold the sash in place.
- Sash Horns: Decorative protrusions on the bottom of the upper sash, initially created to reinforce the joints in much heavier Victorian glass.
- Meeting Rail: The horizontal part of the frames where the top and bottom sashes overlap when closed.
Selecting the Right Material

- Draught Strips: Modern weather-stripping integrated into the channels to prevent wind penetration.
- Low-E Glass: Special finishes that show heat back into the space.
4. Acoustic Insulation

- Spring Balance: These use a pressurized spring hidden within a slimmer frame. They are typically more economical and enable bigger glass areas since the "box" frame does not need to be as broad to accommodate weights.
Upkeep Checklist for Longevity
To make sure sash windows stay in top condition, a regular upkeep schedule is needed, especially for wood options.
Yearly Maintenance Tasks:
- Cleaning: Wash the glass and frames with moderate soapy water.
- Lubrication: Apply a silicone-based lube or beeswax to the sliding tracks to guarantee smooth operation.

|---|---|---|
| Standard uPVC Sash | uPVC | ₤ 600-- ₤ 900 |
| Premium Timber Effect uPVC | uPVC | ₤ 900-- ₤ 1,300 |
| Standard Softwood | Pine/Engineered | ₤ 1,200-- ₤ 1,800 |

Why do my sash windows rattle?
Rattling is normally an indication of a gap in between the sash and the beads (the strips of wood that hold the sash in place). In older windows, this is triggered by wood shrinking. Setting up contemporary brush pile draught-proofing can usually eliminate this issue.
