Reinforcing Stained Glass Windows

Reinforcement is necessary on larger windows. As a rule of thumb, a window more than three square feet should be reinforced. Either reinforcing bar or rod may be used for support. Be sure to consider this when designing the window so that the reinforcement does not intrude or compromise the design of the finished work. In either case the reinforcement is soldered to the back of the panel in one of two ways. The bar should be pre-tinned before use. You will solder the bar in several places at intersecting lines on the window. Rough the areas to be soldered on the bar with steel wool. Apply flux and coat the areas with solder. Doing this will make soldering the bar to the window much easier. Place the bar on edge and solder to the window in the predetermined areas.

When using rod, a length of pre-tinned wire is first soldered at several intersecting lines on the window where the rod will sit. The rod rests on the wire which is twisted around it. Apply a bit of solder to the twisted wire. Solder either end of the rod (or bar) to the edge came. In some cases the rod or bar extends on either side of the panel and is “buried” in the wood casing of the window to provide optimum security. The casing is notched where the bar will fit and filled over to disguise it.

@coldmntbling We do not have any videos on reinforcement on our YouTube channel. However I sure there is a video out there.

Are there any videos out there to show the process of adding reinforcement to a piece?

@justinew18 For this panel, no you do not need to use reinforcement. However, we do suggest that you hang it from using 2 chains 1 chain per hook.

Hi, I a am making a copper foil hanging panel in a geometric design. The panel is long and thin, 2 ft by 8", there will be 2 hooks and a chain at the top. This is the longest hanging panel I have made and normally on smaller panels I would just solder bead the edges. should the panel need reinforcing in the design and or the edges. Many thanks.

@raeglas18 Yes, you will want to use reinforcement with these pieces. Our stained glass expert prefers Strong Line Flexible Steel Reinforcement, item

Hello! I am creating to larger pieces, I have never made anything so large before. One will be 26x18 and the other 56x17. Do I need to install reinforcement to these pieces? What do you recommend I use for reinforcement? Thank you for the help!

@eugeneosentoski There isn't a one-size-fits-all answer to this question unfortunately. For large projects, a rigid (zinc, brass or copper) came border will add considerable support and strength to your art to help ensure it doesn't bow over time. For smaller projects, the came becomes less necessary, but still never a bad choice to include. The wood frame and installation strips will help support the project, and may be all that's needed for some smaller projects. I would encourage you to err on the side of longevity by installing a came border if there's any question.

@ for a 25-1/2" x 31-1/2" panel, reinforcement is usually recommended. This can be in the form of copper reinforcing strip or steel reinforcing strip run through the panel, or zinc rebar applied to the "back side" of the panel. When installing against and existing window, it is suggested that you leave a small space between the panels, and to complete the installation in a manner that won't trap any moisture. Because of this, many artists will use rebar to reinforce the panel, then position the panel so that the rebar is facing the existing window.

@eugeneosentoski You don't how large is the piece? Round? Square? Commercial frame or self-made? GENERALLY, you won't need extra reinforcing but it will depend on the size/shape of the piece and quality of the frame

I am making a copper foiled glass piece that will go into a wooden frame. I will mount the copper foiled glass with 1/4 inch strips of wood that will be tacked to the frame. Will it be necessary to add came around the edges for support or will the wooden sandwich of the frame and the 1/4 in strips be enough support? Thanks.
