Material for enclosure interior

[blhale]

Still planning my cyclone enclosure, OSB exterior ('cause I got a bunch) 2x4's with Roxul batts. But what is a good material to cover the Roxul? I'm considering acoustical ceiling tiles, possibly covered with 1/4" Luan in the areas that might take some abuse like where the collection bin is.

This is assuming the air exiting the filters will continually blow Roxul fibers into the shop....

I just used some 1/2" thick sound insulation board from Home Depot on the inside walls of my enclosure. It might be a slightly higher density than Roxul. I keep the return air duct area at least 18" by 6" to reduce the air speed. I was still worried about it shedding particles into the air, but so far it is holding up.

The soundboard web site recommends sheetrock on the surface. The high density sheetrock and low density soundboard work together to cancel noise.
