[edit] Method of opening

  • Awning: Hinged at the top and opened outwards.
  • Bi-fold: Made up of a number of individual sashes, usually 2, 3 or 4, hinged together.
  • Casement: An opening window fixed to the frame by hinges along one of its edges.
  • Fixed light: A window that is fixed in place and cannot be opened.
  • Louvre: A series of parallel pieces of glazing that are hung on central pivots.
  • Pivot: Hung on one hinge at centre points on each of two opposite sides allowing the window to revolve when opened.
  • Sidehung: A variation on a casement window, side opening controlled by tracks and slides.
  • Tilt and slide: Tilts inwards at the top and slides horizontally behind the fixed pane.
  • Tilt and turn: Include a mechanism that allows them to tilt inwards from one edge or to open inwards from one side.
  • Topguided: Tracks and slides enable the top to slide downwards whist the bottom opens out.
  • Vertical slider / sash: Glass is fitted in ‘sashes’ (moveable panels) that slide vertically past each other.

[edit] Window Energy Rating

The Window Energy Ratings (WER) is a scale developed by the British Fenestration Ratings Council (BFRC) to measure the thermal performance of windows. The BFRC label indicates the rating of the window on a scale running from A+ (the most energy efficient) to G (the least efficient).
