| I have a 34 yr old building that has trusses on 10' spacings, has a steel ceiling & 30" of insulation in the attic We can get some pretty wet snows, read heavy, at times & so far have not had a problem with the trusses. Personally, I would worry about the design of the truss more than the spacing, within reason. A truss with a 1o or 12" bottom chord will hold a lot more than one with an 8". Last year we put up a 80'x120'18' building. Double 10" trusses are on 8' center. It will eventually have a steel ceiling & insulation above. Neighbors put up a 76' x 140' x16' building using single10" trusses. That would tend to worry me but the contractor gauranteed it.
FWIW, In this area I have never been in a building that had the trusses on 4' ceilings. | |
