NFPA 13 (02ed) section A.3.7.1(1)for beam and girder construction states the beams to be "either supported on or framed into girders". Wouldn't the "supported on" help confirm calling a purlin building obstructed? I have treated purlin buildings as obstructed construction in the past. Dewayne

It clearly does not fall into panel construction due to the space above the beam. They are not girders. I am not fighting for or against, I just would like a conclusive answer. Is there not a manufacturer or committee member there that could enlighten us? I would think that the tests run on these storage heads and such would have forced a definition for the manufacturers.

The insulation goes in between the purlins. Is the insulation going on the metal deck roof?If the insulation comes to the bottom of the purlin, it will create a fairly flat ceiling and I would consider it unobstructed. If there is no insulation, I would think it would be considered obstructed. At 02:51 PM 10/18/2007, you wrote: >No, above them.
