I live in a 1960 ex council house.
I have these in 2 rooms, one of which is my daughter's.
I've contemplated knocking it out and placing a hit and miss vent in its place. I don't know what it's made out of though, I've been warned it could crumble and make a real mess?
It seems harder than plastic. So I questioned if it's metal, somewhere in the same area stated it's some form of plaster? I can't see that.
Anyway, I just wanted to know if I'm safe to whack away at this? As I'm really unsure what it is.
