Window Frame Styles Can Affect the Average Double-Glazing Cost

  •  Casement Windows

These windows open outwards and are fixed on hinges. These are more like doors. Attached to the window frame with the help of hinges on either side, these are opened and closed using handles. These are easy to use and, when open, provide ample ventilation. The cost of an uPVC casement window could range from  £600 to £1,800 per window. It could vary in size, number of windows, glazing design, and more.

  • Tilt & Turn Windows

These windows tilt from the top to open inwards as well as swing inwards, resembling a door. These are versatile and practical, providing ample ventilation and fresh air. This type is quite popular in high-rise buildings and modern homes. The double-glazing cost of tilt and turn is at least ¼ times higher than casement windows.

Bay windows have three or more windows that are joined to give a bay shape. Bay & bow windows light up the rooms dramatically and also enhance the aesthetics of the place. Double-glazing these windows is the costliest as the cost can be almost 3/2 times that of double-glazing casement windows.

  • Sash Windows

These window types have movable vertical panels that can slide past one another. The windows are mostly made of wood and give a classic look to the building. Double-glazing sash windows can cost ½ more than casement windows.
