To allow for seasonal expansion or contraction by subtracting 1/8 inch from the measurements of the width and height. These measurements can be sent to a hardware or home center store to have an item cut from stock glass to the right size. Alternatively, you can cut the glass yourself, if you have the tools you need.

After installing the glass After installing the glass, grani.by apply caulking to the edge. This will make the glass weatherproof. Install a glazier’s point on both sides of the frame.

Before applying the putty, work it in a gentle manner until it's soft and free of lumps. Then, roll it into pencil-size strips. Apply the first strip to the frame's corner. Work from one corner to the next, making sure it is even and smooth.

Glazier's Points

Note down the dimensions of the frame. Take these measurements to a hardware store or home center and have the new pane cut smaller than the frame's opening. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new window in the frame and press it into place firmly using your hand. Then, you can use the point of your chisel, or the back of the putty knife to pierce the glazier's facets, as shown in Figure 11. The glazier's points should be in line with the top edge of the pane and the raised shoulders should be just below that lip.

Apply a thin bead of glazing compound on the edges of the new glass and in the rabbet grooves, to seal and protect them. Allow this to dry and cure completely.

After the glazing compound dries and the glazing compound is dry, you can install the new window replacement panes sash. The first step is to coat the wood with a thick layer of linseed.

Remove the glazing points from the rabbets, or the grooves in the sash, where the glass is. If they're difficult to cut out, you can try holding an instrument like a heat gun over them to soften them up first.
