Oh, forgot about the doors for the room. Find solid core doors (wood, fire doors will usually be good). Have someone run a router around all four edges (stopping just before the latch and hinge mount points) so there is a 1/4" grove in the middle of all edges. Make sure it'll be installed into a frame with four sides (not open on the bottom, but with the little bump). Into the routed grove, glue industrial grade felt. This way the door will provide a bit of a seal when closed, and also be ridged on it's own.
