Hi All,
I have a client that is interested in a panel to replace the current window in their door. I seem to remember a discussion about reinforcing bars on both sides of the window. It seems to me that that is overkill, but maybe not. I also wonder if I have room to put 1/4 or 1/8 inch tempered glass on both sides of the panel, will that suffice as reinforcing? Maybe add Strong-line between the lead and glass that goes across the panel.
Thanks,
Tim

There are a number of factors to consider. The first of which is: do they have kids? If so, then maybe your idea of the tempered glass on both sides isn't a bad idea. Otherwise, why cover up the stained glass with two more layers of glass? I dont think it will look good. The reason for bars on both sides of a door is that the panel uis subject to striong forces in both directions: as the door is opened and then closed. In my opinion, the strongline is an oxymoron. It lends little strength to the panel. It simply doesn't have enough rigidity to keep itself straight no less a stained glass panel.

Hi Tim. You cannot rely on sandwiching for reinforcement. Glass and lead will expand and contract with temperature. If the lites are in intimate contact, they will be put under stress and could fracture. In addition it may rattle.
If the sandwich is sealed around the edges, you will also have the effect of barometric pressure which will cause the lites to bow in and out, compounding the problem of temperature changes. With less than 1/4" air gap between the lites and panel, there will be no insulating value in a sealed unit, so that is another consideration if the client wants thermal insulation.
Most tempered glass is 1/4" thick, minimum. Good luck in finding 1/8" tempered. If you do, ask about certification to tempered glass standards. 1/8" is just not enough thickness to create the 9000 psi internal compressive stress that gives tempered glass its characteristics. Those few places that will even do 1/8", do it at your risk with no guarantees.

In Michigan, 1/8 in temepered safety glass is common, and often use with and without leaded glass inserts. It can all be done, but the realization that it will need to be re-done in 5-7 years needs to be taken into consideration.
It is not for use on each side of the house, and if on South side in particular, with no over hang of any kind for shade is inviting disaster. The temperature cycle on a summer day will cause the linseed oil to off gas and stick to the inside of the unit as moisture droplets, then in the evening cool in place leaving a bad situation. A "call back" is guaranteed.
just a thought inthe regard of thermal insulated entry glass...
