hello again...
In my travels this week, I inspected a building that had:
Steel Roof Trusses
Metal Stud Exterior Walls, sheetrocked on the inside; & sided w/ T1-11 wood panels on the exterior (at least I believe they were metal studs...looked like 2X6 nominal...maybe cold-formed load bearing exterior wall metal studs?)
The building was constructed in the 1990's (according to the insured).
Is this an ISO Class III (light non-combustible)...???...or is it ISO Class I simply because it's frame construction?
(reason I'm asking is...I've never come across steel roof trusses on a frame building)
thanx,
MF
