My project design requires that a continuous run of USG Cavity Shaft Wall be installed beyond the limiting height allowance listed in the SA926 brochure. What can I do to solve the problem?
For heights exceeding the limiting height tables found in the System Catalog (SA926) brochure, we recommend installing the 20 gauge x 6" C-H Stud in combination with a standard 4" C-Stud of heavier gauge. The two stud sections should be fastened together (back-to-back with fasteners spaced 12" o.c. and staggered. The design or project structural engineer must review any design.
