Article #133 - Drywall Clips - Code Notes
Metal or plastic drywall clips can be used to replace a third stud at a corner, at a partition intersection backing stud, or in the ceiling to replace a nailer. The reduced attachment (wood to drywall) resulting from the use of dry wall clips allows small movements without drywall cracking and nail pops. Small movements are normal as wood responds to changes in temperature and moisture content over time.
Eliminating unnecessary wood framing within walls can increase the thermal efficiency of the wall system. Less framing allows more insulation to be installed and also eliminates hot and cold spots (from thermal bridging through the frame) within the wall system.
Nails and screws are used only to fasten the clip to the stud; they are not used to fasten the drywall to the clips.
Two-stud corners and drywall clips are often used in combination with airtight drywall, where the drywall and well sealed gypboard seams provide an effective interior air barrier.
