16-25 tpi) as some layers contain light gauge metal, or you may use a circular saw. We recommend a
blade similar to the Bosch “Progressor” (part number T345 XF3). It is also recommended to saw
outside, or use a vacuum system on the saw to reduce dust if you will be cutting many panels. QUIET
SOLUTION HAS RECOMMENDED SAWS AND VACUUM SYSTEMS THAT WORK VERY WELL WITH
QUIETROCK. CALL QUIET SOLUTION FOR SPECIFIC INFORMATION REGARDING THESE TOOLS.
QuietRock cuts quickly, so generally assume 10-15 seconds on average for a 122 cm (4’) cut for labor
budget purposes.
HANG AS USUAL:
4) Secure QuietRock to the studs using #8 or #10 Bugle Head 64 mm (2-1/2”) drywall screws (every
406 mm (16”) minimum). Use coarse thread for wood studs and fine thread for metal studs. Hold
the panel in place until four screws are set. Optional — You may get better results by “shifting” the
panels by 51 mm (2’) over the existing wall and avoiding any screws directly into the studs. Instead,
place screws every 406 mm x 610 mm (16” x 24”) into the layer of drywall below. Nails are not
recommended for long term fastening.
5) Finish securing the QuietRock panel with drywall screws. The screw head should go just below
the surface of the paper. Be careful to drive the screws only enough to dimple the surface it’s easy
to over tighten and cause the screw head to go all the way through the paper surface. If you
accidentally break through the surface, drive another screw nearby.
6) Before putting up the next sheet, apply 3 mm – 10 mm (1/8” - 3/8”) bead of QuietSeal® around
panel perimeter (on the edges of the panel). Then install the adjacent sheet of QuietRock, “squeezing” the
QuietSeal in between them. Be sure to remove excess QuietSeal with a rag (any paint thinner easily
removes QuietSeal) or putty knife as needed. DO NOT LEAVE QUIETSEAL ON THE SURFACE, AS IT
CAN INTERFERE WITH TAPE AND MUD. QuietSeal will remain viscoelastic, i.e. not dry, so it is
necessary to tape and texture over the joints. Always use QuietSeal around electrical boxes and at
the wall perimeter to seal all air gaps completely. See QuietSeal instructions for more detailed
information and apply QuietSeal in accordance with applicable requirements of ASTM C919.
7) Use QuietPutty®, or similar, behind outlet or other boxes. Wrap the putty completely around the
back side of the box.
FINISH AS USUAL:
8) After QuietRock is in place, apply drywall tape along the joints between the two pieces of drywall.
The tape helps hold drywall compound in the gap.
9) Use a wide drywall knife to spread joint compound over the tape. Don’t try to fill the entire gap all
at once; apply a little at a time, and allow it to dry before applying a second coat.
10) Cover the screw heads with drywall compound.
11) Allow the joint compound to dry then sand it smooth. Wear breathing protection during this step
because the process generates a lot of dust.
12) Apply a second coat of drywall compound, allow it to dry, and sand it smooth. Repeat the
process as necessary until the wall is perfectly smooth then finish the walls as desired.
Using QuietRock 530 in Ceiling Construction
To use QuietRock in a ceiling application, simply follow the above instructions for walls. The only
difference in installation will be the number of screws used to hold the panel in place. CONSULT
LOCAL BUILDING CODES ON SCREW PLACEMENT. We recommend screws in rows 610 mm (24”)
apart, and in 305 mm (12”) along the rows, or consulting with a professional to determine what is
needed for your particular application. It is advised that you use a drywall hanger lift to install any
drywall on ceilings properly.
