Question about a ceiling in a pole barn.

[chuck356]

A couple years ago I scraped up enough money to build my retirement building, a 30x63 pole barn built by a company named Blitz, they did an awesome job, I am very happy. I have the building divided into 3 sections: one is cold storage for mowers, skid steer, etc, the center is my shop area, it is finished out as I like, and last but not least the west end is my mancave/office. I have 16" on center studs (like a house) and want to finish the mancave. The side walls are spray foamed but not the roof in this area.

So I an trying to figure out how to go about installing a ceiling in the 30x21 mancave, I want to be able to use blown in insulation after the ceiling is installed. I want to use 7/16 OSB for the ceiling material, or any suggestions you may have, but where I am really getting hung up is the joists (what the ceiling attaches to, not exactly sure on the terminology). The room will be divided off, so it will be roughly 17x21, the other side (13x21), will get it's ceiling eventually. The 17' span to support the ceiling is where I am not sure about.

The roof trusses are really wide spaced (about 9'), and the isn't much else up there to grab onto for support, if that is even permitted with this style of building. I just want a finished room that is easy to heat.

1 x 3 strapping screwed to the bottom of your rafters on 2' centers. Run them perpendicular to the rafters. Attach your ceiling material to the strapping.

Is the room ceiling going to be the same as the building ceiling or will there be an attic/loft space above ?

With your trusses set at 9 foot spacing you will need more than 1 x 3 strapping. That isn't heavy enough to prevent sagging. If you look at your roof they probably used 2 x 4 stood on edge and nailed to the top of the trusses with 6" ring shank nails.

This would work on the bottom chord of the truss but you'll lose 3-1/2" of ceiling height and driving 6" nails over head is hard. In the past we've usually used 2 x 6 on edge between the trusses. Nailing through the truss face into the end of the 2x6. Or you can use joist hangers if you like.

They do make tall rib metal that will span your nine foot spacing if a metal ceiling would work.

What if you just used floor joists or equivalent sitting on your framed walls. You'll need to frame out the exterior walls as well and sit the rafter or joist on it. Tie your wall into existing structure.
