W1) Installation for use as a
Sound Control Panel
(behind gypsum wallboard or other paneling)
To reduce sound intensity, attention must be given to wall openings
for conduits, pipes, ducts, electrical junction boxes and any other
devices. Avoid back-to-back coincidence of openings on opposite
sides of a wall. When the purpose of the openings has been
completed, open spaces must be packed with acoustical
insulation, or otherwise caulked, and sealed with a good grade
acoustical sealant to assure an airtight closure.
Doorstops should be gasketed and dropseals installed at door
bottoms.
Do not caulk between 440 SoundBarrier® panels. This
space allows for the natural expansion and contraction of the 440
SoundBarrier panels. 440 Sound Barrier panels must be installed
vertically. After application of gypsum wallboard, the entire floor-
ceiling wall perimeter must be caulked with acoustical sealant.
W-1-A) To Wood or Metal Framing
1) Apply a 3/8” bead of APA-approved paneling adhesive to studs in
accordance with the adhesive manufacturer’s recommendations.
A double bead of adhesive is necessary on studs where adjoining
panels fall.
2)
Apply 440 SoundBarrier panels vertically to adhesive and framing,
using hand pressure where adhesive is located to insure positive
contact. Allow for expansion gaps as stated at the bottom of page 1.
Screw 12” o.c. along edges and 24” o.c. along all intermediate framing.
Screws should be of sufficient length to penetrate 3/4” into framing.
Hold screws 3/8” back from panel edges.
3) Install gypsum wallboard or other paneling over 440 SoundBarrier
panels so panel joints are staggered and do not coincide. Follow
gypsum wallboard manufacturer’s installation recommendations.
W-1-B) Decoupled Wall System – Reduced
Sound Transmission on Wood or Steel Studs
1) Apply a 3/8” bead of APA-approved paneling adhesive to studs in
accordance with the adhesive manufacturer’s recommendations. A dou-
ble bead of adhesive is necessar
y on studs where adjoining panels fall.
2)
Apply 440 SoundBarrier panels to adhesive and framing, using hand
pressure where adhesive is located to insure positive contact. Allow for
expansion gaps as stated at the bottom of page 1. Screw 12” o.c. along
edges and 24” o.c. along all intermediate framing. Screws should be of
sufficient length to penetrate 3/4” into framing. Hold screws 3/8” back
from panel edges.
3) Stagger gypsum wallboard so edges do not fall onto studs. Using
rock-to-rock screws (#10 x 1-1/2” bugle head screws), secure gypsum
wallboard directly to 440 SoundBarrier panels ever
y 8” o.c. around
panel edges and 12” o.c. on intermediate sections of panel. Do not
fasten the gypsum wallboard into studs.
*Resilient channels or furring strips may also be installed over 440
SoundBarrier panels provided that the channels/strips are screwed through
the 440 SoundBarrier into framing as per manufacturer’s recommendations.
W
-1-C) Double Wall Construction - STC 66
(Using 5/8” 440 SoundBarrier)
1) Construct dual frame 2” x 4” placed 16” o.c.
2) Maintain a 1” dead air space separation between wall framing.
3) Install 3-1/2” high fiber count sound bat insulation in both sides of wall.
4) 5/8” 440 SoundBarrier panels are to be applied directly to wall studs,
each side, with recommended expansion gaps as stated at the bottom
of page 1. Apply 440 SoundBarrier following instructions in section
2 of “1-A) T
o Wood or Metal Framing.”
5) 5/8” fire-rated gypsum wallboard is to be applied directly to 440
SoundBarrier. Use 440 SoundBarrier as a base for the gypsum
wallboard. Using rock-to-rock screws (#10 x 1-1/2” bugle head screws),
secure gypsum wallboard directly to 440 SoundBarrier panels every 8”
o.c. around panel edges and 12” o.c. on intermediate sections of panel.
W-1-D) To Masonry Walls
1)
As per AP
A recommendations, install wood furring strips, not
exceeding 16” o.c. for 1/2” 440 SoundBarrier panels (furring strips not
to exceed 24” o.c. for 5/8” and 3/4” 440 SoundBarrier panels).
2) Apply 440 SoundBarrier panels following instructions in section 2 of
“1-A) To Wood or Metal Framing.”
3)
Install gypsum wallboard or other paneling over 440 SoundBarrier
panels so panel joints are staggered and do not coincide. Follow
gypsum wallboard manufacturer’s installation recommendations.
W2) Installation for use as a
Fabric-Wrapped Panel
440 SoundBarrier panels have different textures on each side. One is a
smoother linen texture and the other a rougher screen texture. Select
the side to apply fabric that best suits your needs. Also notice that,
due to the nature of the product, the sur
faces of
440 SoundBarrier
panels are not perfectly flat; determine the suitability of the panels as
a substrate for your fabric prior to fabric application. (Apply fabric to
a small sample, if necessar
y
, to help make that determination). Lightly
sanding the surface of the 440 SoundBarrier panels will help eliminate
textures and inconsistencies.
