A friend of mine would like a stained glass window with a bespoke design at the top of her stairs to replace the existing window. Real stained glass would be too expensive, even if I was capable and were to have a go myself, so I was thinking of making it with adhesive lead strip and glass paints on a clear "plastic" sheet and then fixing this on the inside of the existing glass. I've seen a few links on t'internet for this kind of thing but have a few questions.
The existing window is a double glazed unit approx 500 mm x 1200 mm.
1 I'm confused re the different materials and what would be best for this. Polycarb? Acrylic?
2 Would 2 mm thickness be OK?
3 Whats the best method for cutting a sheet to the exact size of the existing glass? Score & snap?
4 I was thinking of fixing it to the existing glass by making it a few mm smaller all round and then using a narrow silicone bead to hold it in place. Any other ideas?
5 If I fix it rigidly in place as above, what about differential expansion? Would it buckle?
Grateful for any advice.
Cheers
