Hello,

Just had wooden window frames replaced with uPVC. The old frames had
those
magnetic sensors screwed into the Window/Frame. Whats the best way of
fitting these on the new uPVC frames ? I was told it invalidates the
guarantee if you screw things into them ?

Any thoughts?

Cheers,
Tim.




The bloke that fitted my alarm told me that uPVC doors can be specified
with reed switches built in. I don't know if this is true (and I guess
it's no help to you, but I'd like to know if that is correct or not).
