Sliding and double-hung windows - flexible ventilation and space-saving design

Timber sliding windows give you ventilation without requiring space for an outward-opening window, making them a practical choice for both traditional and contemporary homes and buildings. Because the window opens within its own frame, sliding windows work particularly well alongside decks, pathways and other areas where an outward-opening window could get in the way.

Horizontal or vertical sliding window options


Horizontal sliding windows can be manufactured as single or multi-panel systems, with fixed and sliding panels arranged to suit the opening.
Double-hung windows have two vertically sliding sashes and are especially appropriate for villas, bungalows and heritage-style homes. They retain traditional proportions and character while allowing ventilation through the upper or lower sash.
Options can include:
  • Traditional cord-and-weight double-hung windows
  • Modern balance systems where appropriate
  • Single or multiple-window combinations
  • Fixed lights above, below or beside the opening sashes
  • Glazing bars and heritage mouldings
  • Thermawood double glazing
  • New windows designed to match existing joinery
  • Retrofit double glazing for suitable existing windows
