I was all set to hang some wooden slatted blinds in the bedroom the other
day. I measured up to hang them from the top of the window recess (if
that
makes sense) as we already have curtains up and wanted the blinds for
privacy. When I started drilling the holes, I drilled about 10mm into the
plaster and hit what must be a metal strip. We live in a six year old
house with uPVC glazing.

What's this metal strip for, how thick is it and is it ok to drill
through
it in order to fit the blinds?

Thanks in advance.

===============================
If you hit metal at 10mm you've probably got a 'Catnic' lintel which is a
hollow steel box section. Try continuing drilling with a metal drill for
about about another 4mm and if your drill then breaks through into a void
it will confirm that you've got a 'Catnic'.

If this is confirmed you can attach your blind using self tappers into the
steel lintel.

I have tried drilling through the metal, but it seems very hard and doesn't
like me trying to drill through it, even a pilot hole.
