My question relates to the walls of the new 'study', which is basically the back half of the garage. Wall construction is:
- single-leaf brick - 25mm wooden framework for polyfoam boards - 55mm polyfoam boards, incl 9.5mm plasterboard.
When doing heavy duty work (like worktop battens, and 'kitchen' units, I intend to use fixings that go straight through the intermediate layers, and embed into the original brickwork. That's what I did for the internal partition wall.
But for lighter duty things, like a curtain rail, I get confused. I have a small-ish window (640mm x 850mm approx), and I want some small curtains for it. I could go straight back to the brickwork, and secure that way, but that seems like overkill. Can I get away with plugging the plasterboard with what B&Q term as 'Medium Weight' fixings? Basically oversided looking plugs?
Cheers
