I work in an architectural practice and have heard the term 'res bar'
mentioned quite a few times recently. I'm assuming it's related to
sound and the dampening of, in a wall. Does anybody know what it is?
And before you suggest to ask my work colleagues, I'm at a level in
the firm where I should know what the term means, but don't, so asking
the question would be a bit embarrasing. TIA.
