Document which shows the absorption coefficients for plastic covered rockwool?

I have (or had) this document on my computer somewhere, but I don't remember which doc it is ( I think it's one of the BBC papers that Andre' is always linking to). There was a chart that showed the affect of covering broadband (i.e. - wool filled) absorbers with plastic ranging in thickness from 1 mil to 6 mil (IIRC).

Anybody know which one I'm referring to?

I'm sure Andre will come along and post a link, but in the mean I did a test sort of like that:

Sorry, I don't recall such a document with varying covering material thicknesses.

Uncovered,
Andre

Dang! I literally just read this a few days ago, and now I can't find it!

I'll have to re-double my efforts to find it now. I'll post it up when I track it down.
