    Why

    Noise reduction

    Modern studios require almost incomprehendable sound deadening. The ductboard is used most of the time to eliminate noise traveling through the ducts. Studios are very moisture sensitive so a dehumidifier is probably planned, hence no mold. Am I right David?

    Sound

    New orchestra hall in my town. You can walk through the supply ducts. Noise engineer said the key to low noise is big ducts at low velocity but same needed volume. You may want to see how large you can go.

    David, I'm sorry it took so long to find this I had to dig through the old text books :)

    Red tool = 2 3/4

    Black tool also = 2 3/4

    I can't remember what the blue tool does If you can remind me I'll try to look it up.

    By the way if you'll e-mail a fax number to me I'll gladly send you a few pages from my Owens Corning Manual.

    Your friend in the industry,
    Alan R. Mercurio
