Replacing damage glass in double glazing

[MJT]

One of my double glazed windows, an upstairs one, is misting up and I want to replace the glass panel.

I can lean out of the window and measure the outer edges of the window pane, but I do not know how much to reduce the measurements to get the size of glass panel I need to order.

Regards

The surest way to measure it is to take the glazing beads out, check the dimensions, then pop the beads back in temporarily.

You could work out the dimensions by making deductions but there is a risk that your profiles have a different design from others.
