I'm decorating a room where the fireplace was closed up many years ago

ventilation from the room to guard against condensation in the chimney.
Also the windows have no trickle vents (and being aluminium framed I
can't fit any). I'd prefer a vent we can close when it's parky and
blowing a gale. *Something like a round soffit vent in the skirting
board might be OK but I can't find any which are closable. I don't fancy
a plastic hit-and-miss in the wall or skirting board (we're not
houseproud but there are limits to what 'er indoors will stick). *All
I've found so far are trickle vents for windows which I think I could
fit to the skirting boards by just drilling a line of holes. *(I'm not
up to router work.) *Any other ideas please?
