   24" is fine for stud & truss..

   *Tom, You certainly don't have to worry about the walls coming down from the weight, but personally I don't like studs on 24" spacing if you are using OSB for sheeting because they have a tendency to bow in and out severely. Be sure you leave plenty of space between the sheets so they don't expand and bow the walls. You will get enough bowing just from uneven drying of the studs. If you have a long,unbroken wall and you are using vinyl siding, I can almost guarantee you an ugly looking wavy wall no matter what you sheet it with. Another thing to consider is that 2' spacing on the studs is too far (in my opinion) to use 1/2" sheetrock on the inside.

   *Why not? we hang rock on trusses 2' apart allthe time.

   *We use nothing but cellulose insulation in our houses. 1/2" sheetrock doesn't have the strength to support a ceiling with a heavy blanket of cells without noticeable sagging over time, and walls won't stand up to blown in at that spacing without bowing the sheetrock.

   *Just completed a 1 1/2 story house with 2x6 studs 24" oc. No problem with the code people. Had to use a double top plate otherwise floor joists above must be stacked directly over studs. Use 1/2" OSB sheathing with tar paper and cedar shingles over that. Worked fine. On the interior we used 1" of drywall (thermal mass) and cellulose insulation. Have not had a problem to date.

   *Sandy,One inch of drywall ? That's quite a bit of added expense using double 1/2". Are you aware that USG manufactures 3/4" drywall which achieves a 2 hour fire rating at a price not all that much more than 5/8" ? Just a thought.

   *Yes 24" oc works okay but... gyproc finish on long walls can be wavy. How about framing the walls @ 19.2 " oc 5 stud spacings / 8'. This gives a higher R value to the wall but doesn't compromise as much on wobbly visuals. Again check design values and loads look at code book.

   *Tim:House is passive solar and needed the thermal mass as a heat sink. Seems to be working great. Was not done for fire rating. We looked for 1" board, but it was not available. It was expensive and drywallers did alot of head scratching.

   *1/2" Drywall ceilings hung on 24" centered trusses, after 5 years, have more waves then the ocean during a hurricane. Because it is done does not make it right.Not in my house! No way!
