2. DESIGN AND INSTALLATION CONSIDERATIONS
2.1 Directionality
AcoustAffix
™
panels have three different installation methods. For all installation methods, please note the following in regard to
directionality. Panels are designed to be installed in single panel width rows. All panels can be butted edge-to-edge within each
row in the case of all installation methods. Rows can have panels join short edge-to-short edge (23-3/4", nominal 2' wide) or
long edge-to-long edge (47-3/4" nominal 4' wide). Due to the directional finish of the product, Armstrong Ceilings does not
recommend butting short edges to long edges.
2.2 Edges
Field paint-able panels (item 2012) have square edges on all sides.
Factory painted panels (items 2012WH/BL) have square edges on
the 4' sides but have back-cut edges along the 2' sides.
Because of this back-cut, butting the 2' sides of factory painted
panels edge to edge will result in the visual of a notch that is
0.385" x 0.90" (illus. 2.2).
2.3 Exterior Installations
AcoustAffix panels are not intended for exterior use.
2.4 Direct Attachment to Deck, Structure or Wall
These panels can be installed on ceilings of any slope or on walls when following the suspension and fastening instructions in
this document.
2.5 Plenum
Design limitations require relatively clear deck areas and are not suitable for plenum spaces with services or obstructions that
interupt the attachment surface.
2.6 Fire and Sprinklers
AcoustAffix panels, as with other architectural features located at the ceiling, may obstruct or skew the planned fire sprinkler
water distribution pattern, or possibly delay or accelerate the activation of the sprinkler or fire detection systems by channeling
heat from a fire either toward or away from the device. Please consult a fire protection engineer, NFPA 13, and the local codes for
guidance where automatic fire detection and suppression systems are present.
2.7 Attachment Strength Requirements
Overall system weight will combine the panels and the suspension system.
• Panels weigh 1lb/SF
• HD8906 Drywall Grid weighs 0.3lbs/LF
• Metal or wood furring (refer to manufacturer)
Fastener connections of the suspension system to building structure are specified by the contractor and must follow the
manufacturer’s instructions and reference code.
2.8 Product Durability
AcoustAffix are soft mineral fiber panels and are not recommended for installations below 6' above the finished floor, or in
high-impact locations such as gymnasiums.
