1. GENERAL INFORMATION

1.1 Product Description

AcoustAfﬁx Surface Mount panels for ceilings are 3/4" thick, available in nominal size of 2' x 4', and offer acoustical absorption

when installed in an exposed structure environment. Standard panels are available in Black, White, and a scrimmed panel with no

ﬁnish. The scrimmed panel can be painted post installation to directly match the deck.

Field paintable panels have square edges on all four sides. On factory painted panels the long edges of the panel are square and

the short edges are reverse tegular.

1.2 Safety

During the installation be certain that the work site is well ventilated, and avoid breathing dust. If high dust levels are anticipated

during installation such as with the use of power tools, use appropriate NIOSH designated dust respirator. All power cutting tools

must be equipped with dust collectors. Avoid contact with skin or eyes. Wear long-sleeve, loose-ﬁtting clothes, gloves, and eye

protection.

1.3 Warranty

Failure to follow the Armstrong Ceilings recommended installation instructions in effect at the time of installation will void the

product and/or ceiling system warranty.

1.4 Surface Finish

AcoustAfﬁx panels (Black and White only) feature a ﬁnished latex paint on the face and panel edges.

1.5 Storage & Handling

To avoid damage, the ceiling panels should be stored in a dry interior location in a ﬂat position and should remain in cartons prior

to installation.

1.6 Site Conditions

Building areas to receive ceilings shall be free of construction dust and debris.

AcoustAfﬁx panels with factory paint ﬁnish can be installed in conditions between 32° F (0° C) and 120° F (49° C) and in spaces

before the building is enclosed where HVAC systems are cycled or not operating.

AcoustAfﬁx ﬁeld paintable panels have standard humidity resistance and should be installed in areas where the building is

enclosed and the HVAC is continuously functioning.

These products are not recommended for exterior applications where standing water is present (such as pools), or where

moisture will come into direct contact with the ceiling.

1.7 HVAC Design & Operation, Temperature & Humidity Control

It is also necessary for the area to be enclosed and for the HVAC systems to be functioning and in continuous operations for the

life of the product. All wet work (plastering, concrete, etc.) must be complete and dry. AcoustAfﬁx panels cannot be used in

exterior applications.

1.8 Cleaning/Maintenance

Use a clean, dry, soft, white cloth to wipe off any dust or ﬁngerprints.

How to Install AcoustAffix™ Surface Mount Ceiling Panels 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.

How to Install AcoustAffix™ Surface Mount Ceiling Panels 3. ACCESSORIES FOR USE WITH ACOUSTAFFIX™ PANELS 3.1 Fasteners Armstrong Ceilings provides installers with two types of fasteners. Use the All-in-one Self-stop Fastener, described in Section 3.2, for direct mounting to furring or drywall grid. Use the Truss Mounting Kit, described in Section 3.3, for mounting to trusses. System performance is based on using the appropriate fastener at the correct spacing.

INSTALLING SUSPENSION SYSTEM FOR ALL-IN-ONE SELF-STOP FASTENERS 4.1 Suspension System Overview AcoustAffix™ panels are required to be screw-attached to Furring or Armstrong® Drywall Grid. The use of furring or grid helps to increase the product’s overall NRC performance. 4.2 Furring Recommendations Furring for AcoustAffix panels can be either metal or wood.

How to Install AcoustAffix™ Surface Mount Ceiling Panels 5. INSTALLING PANELS WITH ALL-IN-ONE SELF-STOP FASTENERS 5.1 First Panel and Alignment AcoustAffix™ panels are installed in single panel width rows, butted against each other with no reveal. Because panel edges are butted against each other, the alignment of the first panel determines the straightness of the rest of the panels within the row. Alignment and even spacing in relation to the suspension is critical.
PAGE 6
How to Install AcoustAffix™ Surface Mount Ceiling Panels For all panel layouts, the same spacing and fastener attachment rules apply: • Each full-size panel requires six self-stop fasteners • Exact fastener spacing is based on alignment with furring but should target 20" O.C. between fasteners along the length of the panel and 16" O.C.

Truss width It is recommended to have two installers for truss installations. AcoustAffix™ panels can be mounted to flat trusses using the Truss Mounting Kit. The panels must be installed in pairs and cover both sides of the truss. Panels must be installed in single panel height rows, with the 2' edges of each panel end to end.

ADHESIVE INSTALLATION CONSIDERATIONS 8.1 Area Preparation: Surfaces must be dry and free of dust, grease, oil, dirt or any other material that may deter adhesion. If the paint is flaking or peeling it must be removed. Existing finish paint must be well-bonded and not flaking or peeling. 8.2 Painted Surfaces: Avoid applying to a newly painted ceiling. Glossy painted surfaces must be abraded.
