			6.	Install the first Liner Board panel. The panel length shall be 3/4 inch less than the total height of the framed section. Plumb the panel against the web of the Tabbed Track and bend out tabs in Tabbed Track to secure the panel in place.
			7.	Insert a CT Stud into the top and bottom Tabbed Track and fit tightly over the previously installed 1 inch panel. Allow equal clearance between track and stud at top and bottom Tabbed Track. The stud length shall be 3/4 inch less than the total height of the framed section.
			8.	Install the second 1 inch Liner Board panel inside the Tabbed Track and within the tabs of the CT Studs.
			9.	Install succeeding studs and panels in the same manner as described for the first and second panels until the wall section is complete.
			10.	Anchor the final panel section at 12 inches o.c. with tabs from the Tabbed Track.
			11.	Where wall heights exceed the standard or available length of the Liner Board panels, the panels shall be cut and stacked with joints occurring within the top or bottom third of the wall height. The shorter panels shall be minimum 24 inches long and of sufficient length to engage 2 studs.
			12.	For doors, ducts or other large penetrations or openings, install Jamb Track as perimeter framing. Use 20-gauge track with a 3 inch back leg for elevator doors and block cavity. Install 12 inch wide gypsum filler strips for doors exceeding 7 feet 0 inches height.
		E.	Area Separation Wall: Materials are installed with materials found in Section 09260.
			1.	Foundation: Position 2 inch C-Runner at floor and attach securely to foundation at ends and 24 inches o.c. Caulk under runner at foundation with min. 1/4 inch bead of acoustical sealant when specified to reduce noise transmission.
			2.	First Floor: Install H-Studs and insert Liner Board. Attach two thicknesses of 1 inch Liner Board vertically in C-Runner with long edges in H-Stud. Continue installing H-Studs and Liner Board alternately until wall is complete. Attach horizontal C-Runner to top of Liner Board, fastening flanges of C-Runner at all corners on both sides of Liner Board with 3/8 inch drill point screws.
			3.	Intermediate Floors: Attach C-Runner to C-Runner cap on wall below, staggering end joints at least 12 inches. Fasten C-Runner together using double 3/8 inch screws at ends and 24 inches o.c. Fasten H-Studs to adjacent framing with aluminum breakaway clips. Attach breakaway clips to H-Stud with one 3/8 inch drill point screw and to adjacent wood framing with 1-1/4 inch drywall screw. Install fire blocking between solid wall system and adjacent framing at floor lines, bottom of truss line and any other locations according to code requirements.
			4.	Roof: Cut Liner Board and H-Studs to follow roof pitch. Fasten H-Studs to framing with an aluminum breakaway clip.
		F.	Shaft Wall / Stairwall system finished one side: Materials are installed with materials found in Section 09260.
			1.	Install gypsum board in a double layer on one side, either horizontally or vertically.
			2.	Install the first layer of gypsum board horizontally with approved fasteners spaced 24 inches o.c. and 3 inches from all edges.
			3.	Offset the horizontal joints minimum 12 inches from any splice joints in the Liner Board panels.
			4.	Install the face layer of gypsum board parallel to the framing with approved fasteners spaced minimum 12 inches o.c. and 6 inches from all edges.
