This window was fun to work on. The stained glass is not original to the house but it sure does add to the character of the home. Amazingly, when the glass was originally set, there was no window glazing used. That window was just sitting in the frame with a few glazing points.
That makes for a drafty room, especially considering that’s a bathroom. In old house speak we call that good ventilation.
I picked the window and surrounding trim work clean. Important draft eliminating glazing and caulk is applied. A new storm window is on the way.
It will be as efficient as a new window. To make it so cost me nothing but a few hours of time, my own labor, minimal cost of a new storm and some supplies I already had on hand.
