First of all is there any point in fixing the vibration sensors from the old
wooden windows back onto the new upvc ones? I guess someone could still
break them, albeit with a bit more effort than the old ones?

Secondly, what is the the best way of fixing them? Can you screw into the
upvc or is some sort of sticky stuff a better idea (but maybe not sticky
pads as you wouldnt want to absorb too much vibration). What about sticking
the wires to the frames too?
