Sliding Sash Windows

Sliding sash windows are typically installed in traditional Victorian and Georgian homes to replace existing timber sash windows operated with cords, weights and pulleys. PVCu sliding sash windows have all the style and character of the original designs but with modern day energy efficiency and security built in.

The original box sashes are often removed and the reveals re-lined in plasterboard to create a more modern appearance inside whilst retaining character.


  • Choice of ‘A’ or ‘C’ Rated energy efficient, double glazed PVCu windows to lower your heating bills and keep your home warm
  • ‘Two systems are available. The authentic weight and pulley system with pre-stretched nylon cords, ball race pulleys and weights or, as a more modern option, pre-tensioned spiral balances with lockable ‘fitch’ fasteners.’ 
  • Gold or chrome fittings, traditional ironmongery and sash horns complete the authentic sash window appearance.
  • Both sashes slide independently, whilst having an optional tilt function to enable cleaning from inside or to provide a fire escape
  • External cills replaced as standard
  • Sliding sash windows are often customised with Georgian fret or Astragal bars. Gold or chrome fittings and sash horns complete the traditional sash window appearance. Night vents and child restrictors are also available.
  • 10 year guarantee covering every part of every window – frames, glass, locks, hinges and installation.
  • Every guarantee is covered by the Glass and Glazing Federation Insurance Scheme for complete peace of mind
