For true glass, you will need to order your chosen glass inserts and have them cut to size. Apply caulk or glass clips. Apply silicone caulk to the inside perimeter of the door frame, or screw in glass clips no farther than 12-inches apart. Insert glass and reassemble.

Run a bead of silicone around the inside edge of the opening. Press the glass pane into the opening, wiping away any excess silicone as you go. For extra support, add glazing (push) points to help secure the glass to the door. Use a trowel or putty knife to push the spikes on the points into the wood.

Install Glass in the Cabinet Doors Insert glass into the back of each cabinet door. Cut and paint thin keeper strips to hold the glass in place, positioning them against the glass and securing them to the wooden door with small brads and a brad pusher.
