Vertical Sliding Window

Vertical sliding windows, also known as vertical sliding sash windows or sash windows, are a type of window design characterized by their vertical movement. Here's some additional information about vertical sliding windows based on the description you provided:

  • Two Sashes: Vertical sliding windows typically have two sashes or panels. One of these sashes can be moved vertically, either towards the bottom or top end of the window frame. This design allows for controlled ventilation, as you can open the window by sliding one of the sashes.
  • Taller Than Width: These windows are especially suitable when the height of the window opening is greater than the width. This is in line with the concept of the golden ratio (approximately 1:1.618), which is often considered aesthetically pleasing in design.
  • Operation: Vertical sliding windows are relatively easy to operate. They typically rely on a pair of frame-specific, site-tensioned spiral balances. These balances provide the necessary support and tension to hold the sash in any desired position, making it easy to adjust the window for ventilation purposes.
