Drywall is installed over InSoFast panels in the same exact way it is installed over traditional framing. Simply attach drywall to the InSoFast studs using all-purpose coarse drywall screws. Type W Bugle Head Screws attach single layer gypsum panels to InSoFast framing. Screws provide greater holding power than wallboard nails, minimize popping and help prevent damage to the panels.
Follow the standards set forth by the drywall industry that the screw be at least a #6 x 1-5/8” long Phillips Drive Coarse Thread Drywall Screw for the Flat Panel UX2.0 and a #6 x 2” long Phillips Drive Coarse Thread Drywall Screw Flat Panel EXi 2.5. At a minimum the screw length should be long enough to pierce through the InSoFast stud 1/2″ so the tapered point is all the way through the stud.
This picture demonstrates the variety of fasteners that will work with the stud and not crack or split for a secure and positive attachment for the finishes.
