Measure your insert window carefully

When you want to replace your insert window , two options are available to you:

  • your window is still in place
  • your window is broken

If your glass still fits on your heater door, simply take its dimensions in height and width and then order it.

If your window is broken:

  • You must measure the dimensions of the frame inside the door and subtract  0.118 inches from each side, or 1/4 inch from each dimension obtained, so that the window ordered adapts to the dimensions of your door.
  • (example: your frame is 23.62 inches x 17.72 inches, you must order a window measuring 23.39 inches x 17.48 inches).
  • Please note: depending on the site from which you order, the dimensions to be removed may vary, due to cutting techniques. Be sure to follow the advice given by the supplier with whom you place your order.
