TECHNICAL GUIDE GYPSUM BOARD
ToughRock® Gypsum Products ToughRock® Product Overview ToughRock® Gypsum Boards include paper-faced drywall panels for a wide range of interior and exterior applications, including fire-rated wall and ceiling assemblies, exterior sheathing, soffit and more. The standard-weight, 1/2” panel has been enhanced and now carries a fire rating with the introduction of ToughRock® Fireguard 45® Gypsum Board.
ToughRock® Gypsum Products ToughRock® Interior Gypsum Board Calculator Determine the wall and ceiling areas: Width of the room x Length of the room = Ceiling area (Width + Length) x 2 x Height of the room = Wall area For example, a 12’ x 16’ x 8’ room has a wall/ceiling area of 640 sq. ft. Ceiling area: 12 x 16 = 192 Wall area: (12 + 16) x 2 x 8 = 448; 192 + 448 = 640.
ToughRock® Gypsum Products Interior Gypsum Board Installation ToughRock® Gypsum Board products should be installed according to the most current versions of Gypsum Association GA-216 “Application and Finishing of Gypsum Panel Products” and ASTM C840 “Standard Specification for Application and Finishing of Gypsum Board for Non-Fire Rated Construction.” Walls Several methods are used to attach gypsum boards to the framing including fasteners, adhesives, and fasteners and adhesives together.
ToughRock® Gypsum Products Finishing Interior Gypsum Board Joints/Levels of Finish Please refer to the Recommended Levels of Gypsum Board Finish, Gypsum Association publication GA-214, for recommendations of various levels of finish of gypsum board surfaces prior to the application of specific types of final decoration.

ToughRock® Gypsum Products ToughRock® Shaftliner – Area Separation Wall As land costs and construction costs increase, more builders are constructing multi-family housing. Any time families share walls, there is a concern about safety and comfort. A fire started by a careless tenant can destroy the accumulations of a lifetime. The irritating noise of a neighbor can affect quality of life.
ToughRock® Gypsum Products Installation of 2” (51 mm) Area Separation Wall 1. Position 2” (51 mm) C-Track a minimum 3/4” (19 mm) from the framed wall of the adjacent unit. Fasten C-Track to foundation with fasteners spaced a maximum of 24” (610 mm) o.c. When specified, apply a minimum 1/4” (6 mm) bead of acoustical sealant under the C-Track to maximize acoustical privacy. Run the C-Track to the end of the foundation. In case of offset units, see 15 under Special Conditions. 2.
ToughRock® Gypsum Products Special Conditions 1. When an H-Stud does not align with the adjacent wood framing, insert blocking between wood framing members and attach breakaway clip to blocking using one 1-1/4” (32 mm) drywall screw and to the H-Stud using a minimum of one 3/8” (9 mm) minimum length pan head screw. 2. If gaps are present between back-to-back C-Tracks, caulk using appropriate fire caulking material. 3. When wall framing is spaced greater than 1” (25.

ToughRock® Gypsum Products Shaftwall/ Stairwell Systems ToughRock® Shaftliner is used as a component in a system used to enclose elevator shafts, construct fire rate stairwells, duct protection, air return systems, and horizontal membranes. Unlike heavy and expensive masonry construction in the building core, stairwell/shaftwall enclosures are lighter weight, maintenance-free, and go up quickly without construction delay during cold weather.
ToughRock® Gypsum Products Shaftliner/Stairwell Installation Instructions 1. Lay out per construction drawings. Secure J track as perimeter framing on floor and plumb to ceiling and sides. Attach with fasteners no more than 24” (610 mm) o.c. 2. Install the ToughRock® Shaftliner, cut 3/4” (19 mm) (or as required by fire test reference) less than the total height of the framed section. Plumb the board flush against the web of the J track and secure with 1-5/8” (41 mm) Type S screws 24” (610 mm) o.c.
