Take these measurements to a hardware store or home center and have a piece of stock glass cut to size. You can also cut the glass yourself if have the appropriate tools.

After putting in the new glass After installing the glass, apply some caulking on the edges. This will make the glass weatherproof. Then, place a glazier's tip on each side of the frame to secure the pane into the right place. The points should not be so tight that they create friction between the sash and the frame, but they also shouldn't be loose.

Before applying the putty, knead it thoroughly until it is smooth and free of lumps. Then you can roll it into pencil-sized strips. Place the first strip to the corner of the frame, moving from one corner to another so that it is smooth and even.
