My master bedroom has a set of French doors with a window above the doors. During a recent thunderstorm, I noticed the window was rattling. Upon further inspection, the window is held in with little strips of wood at the top, left and right, but not the bottom. there is also nothing sealing the gap between the glass and the frame/wood.
I'm going to remove the strips and the glass this weekend and reinstall it properly. My question is: what type of product should I use to seal the glass in the frame?
