Fume Hoods in Rad Labs

["Denis J. Rinkacs Jr." <dr4i+@andrew.cmu.edu>]

Good morning all,

I am becoming involved in the set up of my first lab here at CMU.  New
professor is renovating spaces for his new lab.  The architect is
inquiring about specs for the fume hood, primarily material of the
surfaces and ductwork.  My thinking is sheet metal of the normal
thickness for ductwork.  Seamless would be great, but I don't whether
that is cost effective or not.

Any thoughts?

Thanks in advance,
