[Beowulf] materials for air shroud?

I have experimented with some simple ducting for my Limulus
system. I found a Vinyl Flashing from Union Corrugating Company
(purchased at Lowes home center) that has some nice features, it is
bendable, holds its shape, easy to cut, and has a low carbon content
(harder to burn than most plastics), and it is fairly stiff.
My needs are "low temp" air ducting. I have not tested it
with constant warm/hot air.

> Background. We have an older Supermicro SC-823 server with dual
> processors. The air shroud it came with only covers the first
> processor. That didn't matter much when it had two low power processors
> in it, but after upgrading it to dual Opteron 280s, the uncovered second
> one runs considerably hotter than the covered front one. (Swapping the
> processors around didn't help - the heat stayed where it was, so a
> ventilation issue, not a processor issue.) Supermicro does make a newer
> shroud which extends to the back of the case, but the manual (google for
> "SC-823 air shroud user's guide") indicates that it is designed for
> Intel CPUs. So it may or may not fit around the Opterons.
> The redesigned air shroud will probably work, but I'm about 90%
> confident that taping a sheet of plastic onto the back of the existing
> shroud would work as well - if I can find a plastic that won't flap
> around or melt.
