ROCKFON is a leading provider of acoustic stone wool and metal ceiling solutions and suspension systems.
With the acquisition of Chicago Metallic(R), ROCKFON provides customers a complete ceiling system offering combining ROCKFON stone wool and specialty metal ceiling panels with Chicago Metallic suspension systems. ROCKFON is a subsidiary of Denmark-based ROCKWOOL International A/S, the world's largest producer of stone wool products.
For the past 25 years, the ROCKWOOL Group has been present in North America through ROXUL(R) Inc., the leading manufacturer of stone wool insulation products for the North American market. ROXUL has three strategically-placed manufacturing facilities: Milton, Ontario (East), Grand Forks, British Columbia (West) and Marshall County, Mississippi (South). The factories use world-class technology to produce residential products, as well as a wide array of industrial, commercial and marine stone wool insulation products.
ROCKFON acoustic ceiling tiles have performance advantages made possible by a raw material found only in ROCKFON products: stone wool. Stone wool is produced from volcanic rock, or basalt, which features unique properties that give stone wool a number of superior performance characteristics and attributes.

PART 3 EXECUTION
 
3.1
EXAMINATION
A.
Do not begin installation until substrates have been properly prepared.
B.
Verify layout of hangers will not interfere with other work.
C.
Verify acoustical unit layout conditions, which will adversely affect installation.
D.
If layout or substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
E.
Verify wet work such as plastering and concrete is complete and dry. Verify building is enclosed and under standard occupancy conditions prior to start of installation.
F.
Commencement of installation constitutes Installer's acceptance of substrate conditions.
3.2
PREPARATION
A.
Clean surfaces thoroughly prior to installation.
B.
Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
3.3
INSTALLATION
A.
Install in accordance with manufacturer's instructions and in proper relationship with adjacent construction, including the following:
1.
Comply with ASTM C636 and seismic design requirements indicated, according to manufacturer's written instructions and CISCA's "Ceiling Systems Handbook".
2.
Install hangers plumb and free from contact with insulation or other objects within ceiling plenum that are not part of supporting structure or of ceiling suspension system.
3.
Additional Hanger Wires: Wrapped tightly 3 full turns to structure and component at locations where imposed loads could cause deflection exceeding 1/360 span or tolerances specified below.
B.
Measure each ceiling area and establish layout of acoustical panels to balance border widths at opposite edges of each ceiling. Avoid using less-than-half-width panels at borders.
C.
Suspend ceiling hangers from building's structural members, plumb and free from contact with insulation or other objects within ceiling plenum. Splay hangers only where required and, if permitted with fire-resistance-rated ceilings, to miss obstructions; offset resulting horizontal forces by bracing, countersplaying, or other equally effective means.
D.
Where width of ducts and other construction within ceiling plenum produces hanger spacings that interfere with location of hangers, use trapezes or equivalent devices. When steel framing does not permit installation of hanger wires at spacing required, install carrying channels or other supplemental support for attachment of hanger wires.
E.
Do not support ceilings directly from permanent metal forms or floor deck; anchor into concrete slabs.
F.
Do not attach hangers to steel deck tabs.
G.
Install edge moldings and trim of type indicated at perimeter of acoustical ceiling area and where necessary to conceal edges of acoustical panels. Screw attach moldings to substrate at intervals not more than 16 inches (400 mm) o.c. and not more than 3 inches (75 mm) from ends. Miter corners accurately and connect securely.
H.
Install suspension system runners so they are square and securely interlocked with one another. Remove and replace dented, bent, or kinked members.
 
** NOTE TO SPECIFIER ** Include the following paragraphs when seismic rated ceilings are specified. Delete if not applicable.
 
I.
Install seismic separation tees so they are square and securely interlocked with one another, and in compliance with requirements of authority having jurisdiction.

1.
Screw attach moldings to substrate at intervals not more than 16 inches (400 mm) on center and not more than 3 inches (75 mm) from ends, leveling with ceiling suspension system to a tolerance of 1/8 inch in 12 feet (3.2 mm in 3.6 m).
2.
Miter corners accurately and connect securely.
 
** NOTE TO SPECIFIER ** Delete subparagraph below or qualify if exposed fasteners are allowed. Delete if not applicable.

Do not use exposed fasteners, including pop rivets, on moldings and trim.
N.
Acoustic Units:
1.
Fit acoustic units in place, free from damaged edges or other defects detrimental to appearance and function.
2.
Lay directional patterned units in accordance with the approved reflected ceiling plan. Fit border trim neatly against abutting surfaces.
3.
