Shaftliner for Area Separation Walls

Area Separation Walls

Area Separation Walls from CertainTeed (formerly BPB)

offer the advantages of fire resistance and noise

attenuation between adjoining housing units. These

walls offer a 2-hour fire rating line of defense between

units and provide STC sound ratings up to 60-64.

Area Separation Walls are solid type separation walls

assembled using 1" ProRoc® Shaftliner Type X gypsum

board, metal framing and 1/2" ProRoc® Regular gypsum

board for the interior finish. The wall is easily stacked,

floor to floor, allowing progressive construction.

Breakaway aluminum clips are used to attach the interior

wall to adjacent structural framing and provide lateral

support. When one side is exposed to fire, the clips yield

from the heat and break away allowing the gypsum board

interior finish on the fire side to collapse. Thus the area

separation wall remains intact to protect neighboring

spaces.

Area Separation Walls can be built higher, are easier and

faster to construct, lighter weight, and take up less space

than masonry wall systems.

Area Separation Walls

HANDLING AND STORAGEProRoc® gypsum boards should bestacked flat on a smooth, level surface,not stored directly on the ground. Whenspacers are used, position them closelyenough together to minimize warpage.Care should be taken to prevent damageto edges and corners. Always keepProRoc® gypsum board dry prior toinstallation.CertainTeed assumes no responsibility for consequential damages thatmay result from the presence of standing water or where moisture isin direct contact with area separation wall system components.

CUTTINGThe score and snap method is a fast andefficient way to cut gypsum board.Steps:1. On the face side, position a straight

edge along the line of cut.2. Score sheets with a knife or other

suitable tool.3. With a quick, firm motion, snap back

away from the face.4. The back paper can either be cut with

a knife or separated by snapping thepiece in the opposite direction.

WORKING WITH THE PRODUCT5. Smooth all cut ends and edges to

ensure tight joints.

Gypsum boards can also be cut with a saw.For information on avoiding dustinhalation, refer to a Material Safety DataSheet available where CertainTeedproducts are sold. Safety glasses shouldalways be worn when using power tools.To make cut outs, score around theperimeter on the face and back and tapout the waste piece from the face side. Cutouts can also be made with a drywall saw.

INSTALLATIONSteel Framing and Installation of 1"ProRoc® Shaftliner Type X board for SolidType Area Separation Walls are used asthe common wall of one unit. An areaseparation wall can be constructed byfollowing these steps before continuingto frame the adjacent unit.

1. Attach 2" wide C-Track to slab atbottom of wall using suitable fastenersat a minimum of 24" o.c. Allow a 3/4"space from wood stud framing on eachside of the area separation wall.

2. Install vertical C-Track at the beginningof the wall and support as needed.

3. Insert two sections of 1" ProRoc®

Shaftliner Type X gypsum board in bottomchannel and plumb to vertical C-Track.

4. Install 1" ProRoc® Shaftliner Type Xboards vertically. Continue wall asneeded by placing H-Studs between theproceeding panels every 24" for thelength of the wall and enclose the endboards with vertical C-Track.

5. Cap the wall assembly before continuinghigher using C-Track fastened to the H-Studs on alternate sides with 3/8"Type S screws. A second C-Track for thenext row of shaftliner panels is thenplaced back to back with end jointsstaggered at least 12" o.c. and fastenedwith double 3/8" Type S screws at endsand 24" o.c.

6. Attachment Clips: Aluminum angle,0.063" thick, min. 2" wide with min. 2"and 2-1/4" legs. Clips secured withType S screws 3/8" long to “H” studsand with Type W screws 1-1/4" long towood framing through holes providedin clip. Clips spaced a max of 10' o.c.

Surface Preparation of Finished Sides

Joints, corners and fastener heads on theface side shall be finished in accordancewith ASTM C 840, the GA-216, the FireResistance Design Manual GA-600 andjoint compound manufacturer’sinstructions. joint compound shall comply with ASTM C 475.

1. No surface treatment shall be done untilthe interior temperature has beenmaintained at a minimum of 50°F(21°C) for at least 48 hours prior toapplication of compounds and until allmaterials have completely dried.Adequate continuous ventilation mustalso be provided.

2. Fill and level joints with joint compound.3. Embed tape into the wet compound and

allow to dry. For inside corners, crease

the tape and work it into joint.4. Apply a second coat of compound across

the joint and feather to approximately 4"on each side.

5. Apply a third coat and feather toapproximately 6" on each side.

6. Allow each coat to dry before proceeding.7. Attach corner bead to outside corners

and apply three coats of joint compound.Feather out each coat as described insteps 4-6.

8. Spot cover all fastener heads with threecoats of joint compound applied indifferent directions.

9. Lightly sand the last coat of all treatedareas, taking care not to rough thesurrounding gypsum board paper.Smoothing can also be accomplishedwith a damp sponge.

Finishing Interior Walls

ProRoc® gypsum board can be finished withpaint, texture or wallpaper. High qualityprimer/sealer must be used prior to any typeof final decoration. For high gloss paint andsevere lighting conditions, a thin skim coat ofjoint compound should be applied across theentire surface (Level 5 Finish). This will helpminimize the irregularities and porositydifferences between the materials. Refer toGA-214, GA-216, and ASTM C 840 foradditional finishing instructions. Finishing isnot required on area separation wall.

LIMITATIONS• Area Separation Walls are for non load-

bearing partitions only.• ProRoc® gypsum board must not be used

in areas that are continuously orrepeatedly exposed to excessive moistureor dampness.

• Systems shall not be exposed to sustainedtemperatures exceeding 125°F (52°C).

• ProRoc® gypsum board should not comein direct contact with concrete, masonryor other surfaces that have a highmoisture content.

• Unsupported wall height between floorsshould not exceed 12 feet. The assemblymay be used in buildings up to 4 storieswith a total height not to exceed 44 feet.

• Penetrations in Area Separation Walls areusually not allowed by code authorities.
