   if you set the depth well enuf, go for it. I hand nailed it for yrs with roofers (before plastic caps were around)..just dont over drive the bullets. And side asap.

   edit: oh yeah, ya still need ply corners or rack braces..in case yer unsure. Or in a seismic zone, foam may be a NO NO..

   Sorry but that reminded me of ...

   When volunteering some time on a habitat house, a dude was using a framing nailer to apply the foil-backed Iso to the OSB.   ha ha, he had done a whole side of the house before someone stopped him.  Hmm, wonder why the iso isn't staying up?  Maybe because he was shooting the nails right through the iso into the OSB (nails were a weeeeee bit long as well).

   I had a couple "oops" on that volunteer job, but fortunately there isn't anyone here to tell you about it.  (But none of my oops were as bad as the iso guy).  :)jt8

   Hey Everyone,

   Thanks for the replies.

   I seemed to remember using my roofing gun to fasten foam sheathing years ago, but I wasn't really sure.

   Thanks Again.

   Sphere mentioned this earlier but I just want to expand on it.

   Foam sheathing has zero shear capacity so if you're in a higher seismic zone or a high wind zone the omission of the OSB is a bad idea and probably not allowed. If you're in a lower wind or seismic area the code requires bracing but it doesn't need to be sheathing...let-in braces are alright in certain areas. Do not rely on the foam for lateral resistance...if you do, the house will fall over if you slam the front door.

   I think it was a big mistake for that foam manufacturer to advertise foam "sheathing" as a replacement to high priced OSB. Foam is insulation...not sheathing. I can see some law suits down the road from this advertisement

   Amen bro'...I hate to admit it but when I was first starting out framing...cookie cutter 4 br. colonials in Pa. We used 1/2 polyiso..all over..and metel rack braces on the corners.  A skill saw kerf, and a few 7d gunnails is all that it entailed.

   The worse part was one day when I arrived to trim the interior, I saw that someone had taken a knife and cut the vinyl siding, cut the polyiso, wadded up the FG batt, cut the sheetrock, and unlocked the door...all the cords, hoses, compressor...et al...gone.

   If no where else, hang a solid sheet of ply at the doors.!!!!

   I used to trim out those same houses, except in Iowa.

   I was in one one day when a wind storm came up, thought the whole damn house was going to blow away!

   I always said that you could break into one by going through the walls easier than the door way!

   Dang, sounds as bad as a mobile home.  The first mh wall I opened up...  Took panelling off.  Pulled the fg bat out and was looking at sheet metal.  We don't need no stinking sheathing or drywall...

   Then you go work on a REGULAR house and its plaster, lath, rock wool (maybe), 1x sheathing, wood clapboard, crappy sheathing, vinyl/al siding.

   I know which one I'd rather be in when the neighbor gets liquored up and starts firing indiscriminately.jt8

   Did this earlier in the year, insulating under a floor in a crawl space.  1" polystyrene, 1.5" roofing nails in the gun, and tin disks.  Worked great.  Beat trying to swing a hammer while on the back with about 24" clearance, anyway.

   I never met a tool I didn't like!

   Probably shouldn't admit this, but we often used a pnuematic staple gun to apply Styrofoam sheathing.

   Maydell:  Bostitch just came out with a new cap stapler . It shoots a 1" plastic cap held on by a 5/16 crown staple from 3/4 to 1-1/2" long. Its a neat unit and not that all expensive, retails for about $229.00.  Call your local Bostitch tool store and ask about it. Good luck
