Drilling in the loft conversion for curtain pole

pieroabcd

Hi,
I'm not new to DIY, but i'm definitely very new to loft conversions that seem to be made of "fiber of nothing". Frankly my loft doesn't fill me with confidence, to say the least.

I need to install a curtain pole (1.5 m) over the window. With the finger I've knocked the area of the wall around and above the window (not the ceiling, of course) and It's clear that the area around it is hollow while the area above it sounds much less hollow (that doesn't mean that it sounds full like a brick wall).
Is it ok to drill 2+2 holes in the area tha sounds less hollow? Or do I risk getting too deep and damaging the outside, maybe even creating potential for water penetration?

What kind of  drill tips do I need for this kind of walls? I imagine that there's plasterboard and... what else is there behind it?

Thanks.

I'd drill holes with a 6mm masonry drill, if it's hollow or solid you will soon discover which, so use an appropriate plug and don't drill a hole that's much deeper than the screws you intend to use.

~30mm is plenty deep enough. I'd also suggest fixing a batten to the wall to hang the curtain pole from. Put some grab adhesive along the full length of the batten, and use the screws to hold it in place while the adhesive hardens. That way, you are spreading the load over a greater area, and the pole is less likely to fall down.

If it  aloft conversion it’s likely to have an internal stud wall  plasterboard, but might have plywood at the back of the plasterboard. I’d use a small pilot bit to drill/ test hole.
