I've never tried it, but I'm told uPVC doors and windows are easy to
get through with the help of a blow lamp. Plastic melts. Of course
the burglar may suffer from dioxin poisoning. :-)

Good point!
The uPVC doors I looked at, had steel inserts in the uPVC sections. Though the steel inserts weren't very big and weren't
fixed to the uPVC; they were just slotted in.
