B. INSTALLATION FOR USE WITH VINYL, WOOD PARQUET, WOOD STRIP FLOORING, CERAMIC TILE AND ADHERED
CARPETS (USE 4' x 4' AND 4' x 8' SIZE ONLY)
- Follow 2, 3, 4 & 5 of "Installation for use with Carpet and Pad."
- After a minimum of 48 hours, apply 1/4" or greater thickness plywood of suitable underlayment grade* over carpet underlayment.
- Attach plywood over carpet underlayment, assuring that plywood joints do not coincide with the carpet underlayment joints, following the
manufacturer's recommended method and pattern of attachment, making sure that mechanical fasteners are of sufficient length to go
through carpet underlayment into the subfloor a minimum of 1".
- After a minimum of 48 hours, install finish floor covering in accordance with manufacturer's instructions.
*NOTE: Must be suitable thickness and grade acceptable to finish flooring manufacturer also.
Over Concrete Sub-floor-Concrete sub-floor must be dry and integrally waterproofed unless suspended. Carpet underlayment is not
recommended for application in areas where moisture is present. Using maximum 4' x 4' size panels, install carpet underlayment
following appropriate category in "Over Wood Sub-floor," based on the finish flooring to be used, substituting concrete nails or fasteners for
annular threaded nails.
As an alternative, we recommend our ComfortBase product. Ask your supplier for details.
APPLICATIONS AS A WALL PANEL (use 4' x 8', 10' & 12' size only)
Panels should be applied vertically to the framing with blocking or plates at top and bottom of panel. All edges of panel must fall on
framing at all times. Framing for 1/2" thick panels must not exceed 16" o.c. Framing for 5/8" thick panels must not exceed 24"
o.c. During installation, all panels must be installed leaving 1/8" expansion and contraction space between sheets and 1/4"
space at floor, ceiling and around window and door frames, etc. Do not fill or tape panel joints.
A. INSTALLATION FOR USE AS SOUND PANEL (BEHIND SHEETROCK OR OTHER PANELING) -To enhance sound attenuation,
attention must be given to apertures in walls for conduits, pipes, ducts, electrical junction boxes and any openings for other devices. Avoid
back-to-back coincidence of such apertures on opposite sides of a wall. When the purpose of the apertures has been completed, open
spaces must be packed with mineral wool, or otherwise caulked, and sealed with a good grade acoustical sealant to assure an airtight
closure. After application of Type X Gypsum Board, the entire floor-ceiling wall perimeter must be caulked with acoustical sealant. Doorstops
should be gasketed and dropseals installed at door bottoms.
To Wood Framing
- 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).
- Apply wall panels to adhesive and framing, applying hand pressure where adhesive is located to insure positive contact, and nail 12"
o.c. along edges and 24" o.c. along all intermediate framing. Nails should be of sufficient length to penetrate 3/4" into framing. Hold nails
3/8" back from panel edges.
- Follow with application of Sheetrock or other paneling over wall panels, installing so panel joints do not coincide and following
manufacturer's recommendations, securing to wood framing behind wall panels.
NOTE: If adhesive is omitted, nail panels 6" o.c. along all edges and 12" o.c. along intermediate framing.
To Metal Framing
Follow installation instructions in "To Wood Framing," substituting mechanical fasteners where nails are required.
To Masonry Walls
- Install wood furring strips, not exceeding recommended spacing under "APPLICATIONS AS A WALL PANEL."
- Apply wall panels following instructions in "To Wood Framing."
