Does anyone have any info as to what the building code (ibc or ubc) is for residential sheet rock nailing/ screwing? I am building a house in a city that I have not built in before. Below are the inspectors comments on the correction notice. The sheetrock inspection failed due to
1. Too many fasteners too close to butt joints- min 3/8″ by code
2. green board cannot be used as a tile backer
3. Ceilings- GWB reqrd to be perpendicular to rafters/ joists unless framing is 16″ oc
4. edge nailing to be 7″ oc.
When we had the insulation inspection it wasnt the usuall inspector that came out. I asked what they wanted to see on the sheetrock insp because they are very picky here and was hoping to be able to get it right the first time. He told me that there should be 12 screws at the seams and 6 in the field. So I told this to my drywall contractor. Now that the regular inspector is doing the inspection there are too many screws???? I am going to talk to him Monday AM but my experiences with this group has not been good in the past. Its either their way or the highway if you know what I mean.
Item 3 The truss system is a vaulted full hip system. There is a girder truss that runs parallel about 8 feet from the exterior wall. Jack trusses connect to the girder truss and run the 8 feet to the exterior wall. The drywall runs perpendicular to the girder truss and the rest of the trusses from that point on. The seams then run parallel to the jack trusses for the 8 feet from the girder to the wall. Is it code that the rock should be turned at the girder? Seems to me that the way it is done now would be a better way to hold every thing together. The sheet rock on the ceiling is CD board made specially for ceilings. Any insite on this would be appreciated.
