There are a variety of different things to think about when reinforcing stained glass window panels because every window is different. Essentially, it prevents bowing and sagging in years to come by stabilising the window. Larger windows often require more reinforcement but you will have to avoid compromising the design. With that in mind, consider the design before beginning the reinforcement process. If it has both vertical and horizontal lead lines, it is doubtful that it will need as much reinforcement as it will already be very strong.
You’ll also need to factor in things like whether the panel is internal or external; does it move like a door or is it static like a window? The constant opening and closing of a door will cause the window to bow if it is not adequately stabilised. The same applies to external windows that are exposed to the wind and rain from outside.
There are lots of different ways to reinforce a stained glass windows. Steel incased is another reinforced option and better for larger panels and straighter lines, as it doesn’t bend as easily as other materials. Another option is saddle bars, which are metal rods that are drilled into the frame and held to the panel by thin copper ties which are soldered to the panel and then twisted around the saddle bar.
