    Hi,

    what's the best way to fix acoustic foam to the ceiling? I have a concrete
    ceiling, so glueing directly onto the render is no good. And I don't want it
    to "hang through" in the middle. How did you do that?

    Thanks

    If your concrete ceiling is a relatively smooth surface, I don't see
    why "Liquid Nails" or similar tube adhesive would not work. I used
    this stuff to attach acoustic foam and acoustic ceiling tile to a
    drywall ceiling. You might want to work in smaller pieces of acoustic
    foam (say 1' by 1' or 2' by 2') rather than the usual 2' by 4' to make
    the project go easier. The stuff cuts very easily and straight with
    an electric 2-blade carving knife.

    Try gluing the foam to thin sheets of masonite or heavy duty corrugated
    cardboard, then attch that to the concrete with the fastener of choice. 3M
    DualLock works nicely if you don't want to penetrate the concrete.

    Someone (once per thread on this topic, perhaps) should also remind you
    please to keep fire safety in mind, and to choose a type of acoustic foam
    that doesn't easily leap into flames and emit poisonous gases.

    At present there are still many quite dangerous types of acoustic foam on
    the market, in the U.S. at least.

    If you've got the head room, you might consider setting up a net of fishing
    line tied to eye-loop screws in the walls just below ceiling level, and hold
    the foam up that way. There are some acoustic advantages to the foam being
    set off the surface too.
  6. Why not use fiberglass wrapped in acoustically transparant fabric.

    Can all be found/made firerated, plus fg is much more efficient than
    the (often smelly) foam. And you're not stuck with two colors. Fishnet
    is firehazard.

    If in the fiberglass is a panel type, glue it is place, or attach to
    2"x2" strips that are srewed into the ceiling (extra airspace
    increases the effected bandwidth downward (1/4 wavelength thing) .
