If the glass is double-paned, you can take a piece of the old pane to check that the new one fits correctly. Spread a thin layer silicone sealant onto the inner frame rabbet, and then press the new glass onto it. Cut off any excess sealant with the blade of a razor, then paint the exterior to complete.

If you have only one pane of glass, skip this step. If the thickness of your new glass is different from the original one, you'll require a new piece of glass in the proper size from your local glass cutter.
