Examine substrates, areas, and conditions, including structural framing to which acoustical panel ceilings attach or abut, with Installer present, for compliance with requirements specified in this and other Sections # /2/2017

8 SECTION ACOUSTICAL PANEL CEILINGS that affect ceiling installation and anchorage and with requirements for installation tolerances and other conditions affecting performance of acoustical panel ceilings. 1. Proceed with installation only after unsatisfactory conditions have been corrected. 3.2 PREPARATION A. 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, and comply with layout shown on reflected ceiling plans. 3.3 INSTALLATION A. General: Install acoustical panel ceilings to comply with ASTM C 636 and UBC Standard B. Suspend ceiling hangers from building's structural members and as follows: 1. 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. 2. Splay hangers only where required to miss obstructions; offset resulting horizontal forces by bracing, counter-splaying, or other equally effective means. 3. Where width of ducts and other construction within ceiling plenum produces hanger spacing that interfere with location of hangers at spacing required to support standard suspension system members, install supplemental suspension members and hangers in form of trapezes or equivalent devices. 4. Secure wire hangers to ceiling suspension members and to supports above with a minimum of three tight turns. Connect hangers directly either to structures or to inserts, eye screws, or other devices that are secure and appropriate for substrate and that will not deteriorate or otherwise fail due to age, corrosion, or elevated temperatures. 5. Do not support ceilings directly from permanent metal forms or floor deck. Fasten hangers to castin-place hanger inserts, post-installed mechanical or adhesive anchors, or power-actuated fasteners that extend through forms into concrete. 6. 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. 7. Do not attach hangers to steel deck tabs. 8. Do not attach hangers to steel roof deck. Attach hangers to structural members. 9. Space hangers not more than 48 inches o.c. along each member supported directly from hangers, unless otherwise indicated; provide hangers not more than 8 inches from ends of each member. 10. Size supplemental suspension members and hangers to support ceiling loads within performance limits established by referenced standards and publications. C. Install edge moldings and trim of type indicated at perimeter of acoustical ceiling area and where necessary to conceal edges of acoustical panels. 1. Screw attach moldings to substrate at intervals not more than 16 inches o.c. and not more than 3 inches from ends, leveling with ceiling suspension system to a tolerance of 1/8 inch in 12 feet. Miter corners accurately and connect securely. 2. Do not use exposed fasteners, including pop rivets, on moldings and trim. D. Install suspension system runners so they are square and securely interlocked with one another. Remove and replace dented, bent, or kinked members. # /2/2017

9 SECTION ACOUSTICAL PANEL CEILINGS E. Install acoustical panels with undamaged edges and fit accurately into suspension system runners and edge moldings. Scribe and cut panels at borders and penetrations to provide a neat, precise fit. 1. Arrange directionally patterned acoustical panels as follows: a. As recommended by manufacturer by Product type. 2. For square-edged panels, install panels with edges fully hidden from view by flanges of suspension system runners and moldings. 3. For reveal-edged panels on suspension system members with box-shaped flanges, install panels with reveal surfaces in firm contact with suspension system surfaces and panel faces flush with bottom face of runners. 4. Paint cut edges of panel remaining exposed after installation; match color of exposed panel surfaces using coating recommended in writing for this purpose by acoustical panel manufacturer. 3.4 CLEANING A. Clean exposed surfaces of acoustical panel ceilings, including trim, edge moldings, and suspension system members. Comply with manufacturer's written instructions for cleaning and touchup of minor finish damage. Remove and replace ceiling components that cannot be successfully cleaned and repaired to permanently eliminate evidence of damage. END OF SECTION # /2/2017
