This Section includes ceilings consisting of new replacement acoustical panels and exposed suspension systems <br /> as needed due to demolition activities. <br /> B. This Section includes sound batts installed over the ceiling tiles as noted on the drawings. <br /> 1.2 SUBMITTALS <br /> A. Product Data: For each type of product specified. <br /> 1.3 QUALITY ASSURANCE <br /> A. Installer Qualifications: Engage an experienced installer who has completed acoustical panel ceilings similar in <br /> material, design, and extent to that indicated for this Project and with a record of successful in-service performance. <br /> B. Source Limitations for Ceiling Units: Obtain each acoustical ceiling panel from one source with resources to provide <br /> products of consistent quality in appearance and physical properties without delaying the Work. <br /> C. Source Limitations for Suspension System: Obtain each suspension system from one source with resources to <br /> provide products of consistent quality in appearance and physical properties without delaying the Work. <br /> 1. Obtain both acoustical ceiling panels and suspension system from the same manufacturer. <br /> D. Fire-Test-Response Characteristics: Provide acoustical panel ceilings that comply with the following requirements: <br /> 1. Fire-response tests were performed by UL, ITS/Warnock Hersey, or another independent testing and <br /> inspecting agency that is acceptable to authorities having jurisdiction and that performs testing and follow-up <br /> services. <br /> 2. Surface-burning characteristics of acoustical panels comply with ASTM E 1264 for Class A materials as <br /> determined by testing identical products per ASTM E 84. <br /> 3. Products are identified with appropriate markings of applicable testing and inspecting agency. <br /> 1.4 DELIVERY, STORAGE,AND HANDLING <br /> A. Deliver acoustical panels and suspension system components to Project site in original, unopened packages and <br /> store them in a fully enclosed space where they will be protected against damage from moisture, direct sunlight, <br /> surface contamination, and other causes. <br /> B. Before installing acoustical panels, permit them to reach room temperature and a stabilized moisture content. <br /> C. Handle acoustical panels carefully to avoid chipping edges or damaging units in any way. <br /> 1.5 PROJECT CONDITIONS <br /> A. Environmental Limitations: Do not install acoustical panel ceilings until spaces are enclosed and weatherproof, wet- <br /> work in spaces is complete and dry, work above ceilings is complete, and ambient temperature and humidity <br /> conditions are maintained at the levels indicated for Project when occupied for its intended use. <br /> 1.6 COORDINATION <br /> A. Coordinate layout and installation of acoustical panels and suspension system with other construction that <br /> penetrates ceilings or is supported by them, including light fixtures, HVAC equipment, fire-suppression system, and <br /> partition assemblies. <br /> 1.7 EXTRA MATERIALS <br /> A. Furnish extra materials described below that match products installed, are packaged with protective covering for <br /> storage, and are identified with labels describing contents. <br /> 1. Acoustical Ceiling Units: Full-size units equal to one box of each type, size and color of acoustical units <br /> installed. <br /> PART2 -PRODUCTS <br /> 2.1 MANUFACTURERS <br /> A. Products: Subject to compliance with requirements, provide one of the products indicated for each designation in <br /> the Acoustical Panel Ceiling Schedule at the end of Part 3. <br /> ©BOOMERANG DESIGN#1835 0951 13-1 510 Meadowlands Drive,Hillsborough, NC <br /> ORANGE COUNTY,NC 11/15/18 <br />
