Sliding Sash windows are a classic window style that has been popular for centuries, particularly in traditional British architecture. Here are the key points about sash windows:

What Are Sash Windows?

Sash windows consist of two framed panels (sashes) that slide vertically up and down within the window frame. The sashes are counterbalanced by weights connected to cords and pulleys hidden inside the frame, allowing smooth operation.

Key Features

  • Typically have two sashes – one in front and one behind
  • Slide vertically to open, rather than swinging outward
  • Often divided into multiple small panes using glazing bars
  • Counterbalance system allows sashes to stay in position when opened

Types of Sash Windows

  • Single-hung: Only bottom sash moves
  • Double-hung: Both top and bottom sashes can move independently
  • Georgian: Multiple small panes in a 6-over-6 pattern
  • Victorian: Fewer, larger panes in a 2-over-2 pattern
  • Edwardian: 6-over-2 pattern combining Georgian and Victorian styles

Benefits

  • Excellent ventilation options
  • Classic, elegant aesthetic
  • Adds character and value to homes
  • No outward swing, good for tight spaces
  • Can be energy efficient with modern glazing

Considerations

  • May require more maintenance than other window types
  • Can be more expensive initially
  • Older versions may be less energy efficient

Sash windows remain popular for their timeless style and ability to complement both period and contemporary homes. Modern versions often incorporate energy-efficient glazing and materials while maintaining the classic look

Materials:

Sliding sash windows are typically made from two main materials:

  • uPVC (unplasticized polyvinyl chloride):
    • More affordable option
    • Low maintenance – doesn’t require painting
    • Good thermal efficiency
    • Typical cost range: £825 – £1,500 per window installed
  •  
  • Timber:
    • Traditional, authentic look
    • Higher cost than uPVC
    • Requires more maintenance (painting/staining)
    • Typical cost range: £1,500+ per window installed
  •  

Colours

  • White is the most common and affordable colour for uPVC sash windows
  • uPVC windows are available in woodgrain foil finishes to mimic timber
  • Popular colour options include:
    • White
    • Cream
    • Golden Oak
    • Rosewood
    • Black
    • Grey
  •  
  • Timber windows can be painted any colour

Costs

Factors affecting cost include:

  • Size of window
  • Material (uPVC vs timber)
  • Glass type (standard vs acoustic etc.)
  • Color/finish
  • Additional features (decorative bars, run-through horns etc.)

Typical price ranges:

  • uPVC sash windows: £825 – £1,505 per window installed
  • Timber sash windows: £1,500+ per window installed
  • Draught proofing existing sash windows: £280 – £385 per window
  • Full restoration of existing sash windows: £500 – £2,005 per window

Overall, uPVC offers a more affordable option while timber provides a more authentic traditional look at a higher price point. The exact cost will depend on the specific requirements and features chosen.
