1.4 SYSTEM DESCRIPTION
Continuous/Wall-to-Wall
1.5 SUBMITTALS
A. Product Data: Submit manufacturer's technical data for each type of acoustical ceiling unit and
suspension system required.
B. Samples: Minimum 6 inch x 6 inch samples of specified acoustical panel; 8 inch long samples of
exposed wall molding and suspension system, including main runner and 4 foot cross tees.
C. Shop Drawings: Layout and details of acoustical ceilings show locations of items that are to be
coordinated with, or supported by the ceilings.
D. Certifications: Manufacturer's certifications that products comply with specified requirements,
including laboratory reports showing compliance with specified tests and standards. For acoustical
performance, each carton of material must carry an approved independent laboratory classification
of NRC, CAC, and AC.
E. If the material supplied by the acoustical subcontractor does not have an Underwriter's
Laboratory classification of acoustical performance on every carton, subcontractor shall be required
City of Rosemead, California Addendum 2, Garvey Park Restroom Renovation Project, Project No. 31017 Document Control Page 16 of 23
to send material from every production run appearing on the job to an independent or NVLAP
approved laboratory for testing, at the architect's or owner's discretion. All products not
conforming to manufacturer's current published values must be removed, disposed of and replaced
with complying product at the expense of the Contractor performing the work.
1.6 SUSTAINABLE MATERIALS
Transparency: Manufacturers will be given preference when they provide documentation to support
sustainable requirements for the following: Material ingredient transparency, Removal of Red List
Ingredients per LBCV3, Life Cycle impact information, Low-Emitting Materials, and Clean Air
performance.
1. Health Product Declaration. The end use product has a published, complete Health Product
Declaration with disclosure at a minimum of 1000ppm of known hazards in compliance with the
Health Product Declaration open Standard.
2. Declare Label. The end use product has a published Declare label by the International Living
Future Institute with disclosure of 100 ppm with a designation of Red List Free or Compliant (less
than 1% proprietary ingredients).
3. Low Emitting products with VOC emissions data. Preference will also be given to manufacturers
that can provide emissions data showing their products meet CDHP Standard Method v1.1 (Section
01350).
4. Life cycle analysis. Products that have communicated lifecycle data through Environmental
Product Declarations (EPDs) will be preferred.
5. End of Life Programs/Recycling: Where applicable, manufacturers that provide the option for
recycling of their products into new products at end-of-life through take-back programs will be
preferred.
6. Products meeting LEED V4 requirements including:
Storage & Collection of Recyclables
Construction and Demolition Waste Management Planning
Building Life-Cycle Impact Reduction
Building Product Disclosure and Optimization Environmental Product Declarations
Building Product Disclosure and Optimization Sourcing of Raw Materials
Building Product Disclosure and Optimization Material Ingredients

City of Rosemead, California Addendum 2, Garvey Park Restroom Renovation Project, Project No. 31017 Document Control Page 17 of 23
1.7 QUALITY ASSURANCE
A. Single-Source Responsibility: Provide acoustical panel units and grid components by a single
manufacturer.
B. Fire Performance Characteristics: Identify acoustical ceiling components with appropriate
markings of applicable testing and inspecting organization.
a. Surface Burning Characteristics: As follows, tested per ASTM E 84 and complying with
ASTM E 1264 Classification.
C. Acoustic Panels: As with other architectural features located at the ceiling, may obstruct or skew
the planned fire sprinkler water distribution pattern through 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. Designers and installers are advised to consult a fire protection en gineer,
NFPA 13, or their local codes for guidance where automatic fire detection and suppression systems
are present.
D. Coordination of Work: Coordinate acoustical ceiling work with installers of related work
including, but not limited to building insulation, gypsum board, light fixtures, mechanical systems,
electrical systems, and sprinklers.
1.8 DELIVERY, STORAGE AND HANDLING
A. Deliver acoustical ceiling units to project site in original, unopened packages and store them in a
fully enclosed space where they will be protected against damage from moisture, direct sunlight,
surface contamination, and other causes.
B. Before installing acoustical ceiling units, permit them to reach room temperature and a stabilized
moisture content.
C. Handle acoustical ceiling units carefully to avoid chipping edges or damaged units in any way.
1.9 PROJECT CONDITIONS
A. Space Enclosure:
Standard Ceilings: Do not install interior ceilings until space is enclosed and weatherproof; wet
work in place is completed and nominally dry; work above ceilings is complete; and ambient
conditions of temperature and humidity are continuously maintained at values near those intended
for final occupancy. Building areas to receive ceilings shall be free of construction dust and debris.
HumiGuard Plus Ceilings: Building areas to receive ceilings shall be free of construction dust and
debris. Products with HumiGuard Plus performance and hot dipped galvanized steel, aluminum or
stainless steel suspension systems can be installed up to 120°F (49°C) and in spaces before the
building is enclosed, where HVAC systems are cycled or not operating. Cannot be used in exterior
applications where standing water is present or where moisture will come in direct contact with the
ceiling.
City of Rosemead, California Addendum 2, Garvey Park Restroom Renovation Project, Project No. 31017 Document Control Page 18 of 23
HumiGuard Max Ceilings: Building areas to receive ceilings shall be free of construction dust and
debris. Ceilings with HumiGuard Max performance can be installed in conditions up to 120°F (49°C)
and maximum humidity exposure including outdoor applications, and other standing water
applications, so long as they are installed with either SS Prelude Plus, AL Prelude Plus, or Prelude
Plus Fire Guard XL suspension systems. Products with Humiguard Max performance can be installed
in exterior applications, where standing water is present, or where moisture will come in direct
contact with the ceiling. Only Ceramaguard with AL Prelude Plus suspension system can be installed
over swimming pools.

PART 3 - EXECUTION
3.1 EXAMINATION
A. Do not proceed with installation until all wet work such as concrete, terrazzo, plastering and
painting has been completed and thoroughly dried out, unless expressly permitted by
manufacturer's printed recommendations. (Exception: HumiGuard Max Ceilings)
3.2 PREPARATION
A. Measure each ceiling area and establish layout of acoustical units to balance border widths at
opposite edges of each ceiling. Avoid use of less than half width units at borders, and comply with
reflected ceiling plans. Coordinate panel layout with mechanical and electrical fixtures.
B. Coordination: Furnish layouts for preset inserts, clips, and other ceiling anchors whose installation
is specified in other sections.
1. Furnish concrete inserts and similar devices to other trades for installation well in advance
of time needed for coordination of other work.
3.3 INSTALLATION
A. Follow manufacturer installation instructions
B. Install suspension system and panels in accordance with the manufacturer's instructions, and in
compliance with ASTM C 636 and with the authorities having jurisdiction.
C. Install wall moldings at intersection of suspended ceiling and vertical surfaces. Miter corners
where wall moldings intersect or install corner caps.
D. For reveal edge panels: Cut and reveal or rabbet edges of ceiling panels at border areas and
vertical surfaces.
E. Install acoustical panels in coordination with suspended system, with edges resting on flanges of
main runner and cross tees. Cut and fit panels neatly against abutting surfaces. Support edges by
wall moldings.
F. Install acoustical panels in coordination with suspended system, with edges resting on flanges of
main runner and cross tees. Cut and fit panels neatly against abutting surfaces. Support edges by
wall moldings.
