Does anyone know if it is still possible to purchase the thin foil strip that was used for alarming windows in the old days. I have tried google but no luck.

Don't use it on anything that might contaminate it. It corrodes and goes open circuit.

We didn't use aluminium at Chubb, it was soft lead. You fitted it by masking a strip with tape, painting it with varnish, sticking the tape on and then varnishing it again.

I always thought it aluminium in days gone by, but then I just assumed. Anyhow another question. Are the connectors attached to the glass or the frame?

It was over 30 years ago when I worked at Chubb, things probably changed.
The chubb ones were on the glass and were connected to a junction box on the frame with fine wire that would break if the glass were removed from the frame.

how were the corners done, where the lead changes direction on the glass? I suppose it could be folded over, but I always saw square corners.

You fold it up which gives a 45 degree angle and then you fold it down which gives a 90 degree angle that covers the 45 degree angle.
Not that I ever did any like that.

thanks, now I know. I wonder how foil oxidation was prevented in storage, the stuff was always bright finished.
