Fully tested and approved assemblies for shaftwall construction
Provides maximum flexibility to choose from a variety of board manufacturers.
ClarkDietrich provides fully tested and approved assemblies for shaftwall construction. What makes the ClarkDietrich system unique is that it has been tested with almost every gypsum board and shaft liner manufacturer in the country. Unlike competing systems, the ClarkDietrich C-T Stud and J-Track system provide maximum flexibility to choose from a variety of board manufacturers. Other systems are only tested with one type of gypsum board and shaftliner.
This unprecedented flexibility means quick availability of product at economical costs. It provides you with a choice and peace of mind knowing you’re using a tested and approved assembly.
Shaftwall System consists of 1" shaftliner panels supported by 2-1/2", 4" or 6" C-T Studs and faced on one side with two layers of 5/8" type "X" or 1/2" type "C" gypsum wallboard.
Stairwall Systems are designed to enclose stairwalls, this system is finished on both sides with a single layer of 1/2" fire code board.
Shaftwall systems are interior nonload-bearing fire rated wall assemblies that provide critical, life safety, fire-resistant protection for elevator shafts, stairwells, vertical chases and mechanical enclosures. Shaftwalls in elevators and stairwells are one of the most important wall assemblies in a building. They provide the only means of evacuation from the building in an emergency. Vertical chases and mechanical enclosures keep vital communication, power, water, fresh air and exhaust systems intact when a fire occurs.
Cavity shaftwalls are constructed utilizing one of two methods: masonry/CMU or light-gauge steel and gypsum. Gypsum drywall shaftwall construction has become the preferred and most widely used shaftwall assembly. These shaftwalls are lightweight, install faster, and provide lower inplace costs. They also significantly reduce structural framing and foundation costs. Masonry shaftwalls in high-rise buildings historically weigh between 20 and 45 lbs. per square foot compared to gypsum assemblies that weigh between 10 and 13 lbs. per square foot.
In addition to substantial weight reduction, gypsum shaftwall assemblies can be installed from the exterior of the shaft at each floor, eliminating the need for scaffolding. Shaftwall installation is easy, quick and clean. Light-gauge steel and gypsum assemblies provide fast, lightweight, low-cost and high-performance assemblies.
ClarkDietrich C-T Stud Profile
ClarkDietrich C-T Cavity Shaftwall Studs are rigid high-performance members engineered to maintain shaftwall integrity. C-T Studs are designed for use with 1" thick gypsum shaftliner panels. C-T Studs are friction-fitted between top and bottom J-Track. Gypsum shaftliner panels are inserted into the stud flanges. The flanges provide an airtight friction fit along the length of the panel. Studs are automatically spaced 24" o.c. maximum. The system is finished with fire rated gypsum board to complete and achieve the designated fire rating.
C-T Studs are available in 22mils (25ga), 33mils (20ga) and 43mils (18ga).
43mils (18ga) C-T Studs are only available in select markets (43 mils/18ga C- T Studs are for interior systems only)
ClarkDietrich J-Tabbed Track Profile
ClarkDietrich J-Track is used at the floor and ceiling in shaftwall assemblies. C-T studs and gypsum shaftliner panels are friction fit between the top and bottom J-Tracks. J-Tracks have unequal legs. The longer leg (available in 2-1/4" and 3") is installed against the shaft. The leg provides a backstop for easy installation of the liner panel. Three-inch leg track is typically used as a jamb strut around closure details, including duct and door openings, abutments and intersections.
J-Tracks are available with optional "tabs" for ease of C-T Stud spacing.

INSTALLATION REQUIREMENTS
*** Reference design assemblies and gypsum board manufacturer for details of the wall system ***
- Reference ICC-ES Evaluation Report ESR-5050 for detailed requirements of construction of ShaftWall assembly.
- In structural steel-frame construction, install perimeter J-Track sections before applying spray-on fireproofing.
- Pre-cut C-T studs 3/4" less than the opening’s height between top and bottom J-Track.
- Items to be anchored to the wall (cabinets, sinks, handrails, etc.) should be fastened to steel plates secured behind or between layers of 1/2" gypsum.
- Use Type-S screws for 25-gauge steel framing. Use type S-12 screws for 20-gauge (or heavier) steel framing.
- It is important that the job engineer approve the type, size, and maximum spacing of track fasteners to meet the design load requirements.
LIMITATIONS OF USE
- DO NOT STACK WALLS
- Shaftwall assemblies are designed as interior non-load-bearing partitions only.
- Do not install in areas which will be adjacent to occupancies of unusually high moisture conditions.
- C-T Studs cannot be spliced. They must be installed full length and one piece. J-Tracks when not attached to the structure shall not be spliced. Do not attach the J-Tracks to the C-T Studs unless noted otherwise by the manufacturer's installation procedures.
- All Shaftwall members shall be simple span members with no intermediate supports.
- Provide control joints so that maximum length of continuous partition is 30 feet. Wherever possible, the partition control joints should coincide with those in the building structure.
- Elevator door frames should be supported independently of the shaftwall. However, interfacing of elevator frame to shaftwall system may require attachment with jamb clips and/or grouting.
- Where penetrations occur in the partitions, additional reinforcement at corners may be necessary to distribute stresses if control joints are not used and if excessive loads need to be supported.
- To prevent air movement and resulting whistling, the partition perimeters, as well as all penetrations, should be effectively sealed with a non-hardening sealant.
- Finishing of all joints in face layers should be done within temperature limitations of the specific joint treatment used.
- Not recommended for use as an unlined HVAC supply shaft or duct.
- Hollow cavities must be fire stopped at each floor.
- Openings and Penetrations in Shaftwall/Stairwell systems: As tested per ASTM E119/UL 263, these systems do not contain any Openings or Penetrations.
- All Opening and Penetration covering assemblies must be approved for use per Section 713.7 and 713.8 of the 2018 IBC.
- Any Opening or Penetration framing detail provided here is not a tested detail, but a generally accepted practice coinciding with approved assemblies in noted a. above.
- C-T Studs are Nonloadbearing, and where an Opening or Penetration is required the J-Track must be supported by a designed structural element.
- All Opening or Penetration fire rated assemblies require independent structural support, as the Shaftwall/Stairwell systems are not designed or tested under this condition.
LOCATION OF GYPSUM BOARD JOINTS
- Shaftliner panels may be abutted (spliced or stacked) within the cavity as shown in the drawing to the right. The shorter panel should be at least two feet long or of sufficient length to engage two stud tabs on each panel edge. NOTE: In addition, some local codes may also require that these splices be back-blocked with a 12" x 24" piece of gypsum even though the tests were preformed with these joints unblocked. Also, back blocking may be done with the C-T Stud of proper length and placed horizontal. Please check with your local jurisdiction.
- For the shaftwall system, finished one side, install the first layer of 1/2" fire code board horizontally with 1" Type-S screws spaced 24" o.c. and 3" from all edges. The horizontal joints must be offset from any splice joints in the shaftliner panels by at least 12".
- The face layer, also fire code board, installed parallel to framing with 1-5/8" Type-S screws spaced 12" o.c. at all framing members maintaining a 6" edge distance. All edge and end joints should be offset from the base layer by 24".
- For the stairwall system, finished both sides, each side must be installed vertically with 1" Type-S Screws spaced 12" o.c. maintaining a 3" distance from edge. Offset edges and ends on opposite sides 24" o.c.
- Caulk all perimeter edges and abutments with dissimilar materials, and penetrations in the facing layers with a non-hardening flexible sealant.
- All joints on face layers are to be taped and finished and fastener heads finished with joint compounds meeting ASTM C475 standard specification.
INSTALLATION - VERTICAL SHAFTWALLS
- Layout per construction drawings. Secure J-Track as perimeter framing and plumb to ceiling, floor and sides. Attached with suitable fasteners, spaced not more than 24" o.c. Apply a bead of non-hardening, flexible sealant to the perimeter.
- Pre-plan the stud layout 24" o.c. and adjust the spacing at either end so the end studs will not fall closer than 12" from the end.
- Erect the first 1" Shaftliner panel, cut 3/4"-1" less than the total height of the framed section. Plumb the panel against the web of the J-Track and bend out optional tabs in J-Track to secure panels in place.
- Insert C-T Stud, cut 3/4" less than overall height, into the top and bottom J-Tracks and fit tightly over previously installed 1" panel. Allow equal clearance between top and bottom J-Track.
- Install the next 1" Shaftliner inside the J-Track and within the tabs of the C-T stud.
- Progressively install succeeding studs and panels as described above until the wall section is enclosed. The final panel section may be secured with tabs from the J-Track at 12" o.c.
- Where wall heights exceed the standard or available length of Shaftliner panels, the panels may be cut and stacked with joints occurring within the top or bottom third points of the wall. Joints of adjacent panels should be alternately staggered to prevent a continuous horizontal joint. Gypsum panels must engage a minimum of 2 tabs.
- C-T Studs cannot be spliced. They must be installed full height, one piece.
- For doors, ducts or other large penetrations or openings, install J-Track as perimeter framing. Use 20-gauge track with a 3" back leg for elevator doors and block cavity with 12" wide gypsum filler strips for doors exceeding 7'-0" height.
