4. Acoustic Insulation

To ensure sash windows remain in top condition, a routine upkeep schedule is needed, particularly for wood alternatives.
Annual Maintenance Tasks:

- Visual Inspection: Check for indications of flaking paint or timber rot, especially on the sill (the bottom-most part).
- Hardware Check: Ensure sash locks and lifts are tight and functioning properly.
- Cable Inspection: For standard windows, check the sash cables for tearing to prevent the weights from dropping.
