Polycarbonate glazing on 1930's front door

We have a 1930's front door which (together with its surrounding framework) is mostly leaded stained glass. We've recently had some glass replaced (at a considerable cost) and it was suggested that we try and put some Polycarbonate sheets on the outside to protect the glass from future damage. The rebate is at least 1/2 an inch deep but I was wondering what thickness I should be using in order to get the best protection but ensuring that it can be beaded up to fit it over the top of the existing leaded glass.

Has anyone tried this on this forum before or something similar perhaps?

Any information will be appreciated.

As above said, use glass maybe even laminated, poly will start to discolour and scratches easy

I hadn't considered real glass as I wanted something that was going to be difficult to break in the first instance. Also, I hadn't planned on taking out the existing beading from around the stained glass so it was a case of fitting some polycarbonate the size of the existing glass and then add new beading to that which would merge into the existing pattern.

However, now that real glass has been suggested, I would expect to have to remove the existing beading first so that there is enough depth to fit new beading as I would need the panels to be thicker if I use glass.

I think the original suggestion of using polycarbonate would be a much easier option.
You can get solid polycarbonate sheets in different thicknesses, so you can order in a thickness that would suit your needs.
It is totally clear and has all the properties of glass but the advantage is that unlike glass, you can cut it yourself. It is much lighter than glass and so easy to handle, and it is practically unbreakable - so gives you all the benefits you originally wanted.
