RECESSED LUMINAIRES SHALL BE SEALED WITH A GASKET OR CAULK BETWEEN THE HOUSING AND INTERIOR WALL OR CEILING COVERING.

SOUND CONTROL GUIDELINES A. B. C. D. E. F. G. H. I. J. K. OPENINGS AND PENETRATIONS IN CONSTRUCTION ASSEMBLIES FOR PIPING, ELECTRICAL DEVICES, RECESSED CABINETS, BATHTUBS, SOFFITS, OR HEATING, VENTILATING OR EXHAUST DUCTS SHALL BE SEALED, LINED INSULATED OR OTHERWISE TREATED TO MAINTAIN THE REQUIRED STC RATING OF THE ASSEMBLY. FLOOR ASSEMBLIES THAT ARE CARPETED GENERALLY MEET THE MINIMUM IIC REQUIREMENTS. FLOOR ASSEMBLIES WITH HARD SURFACE FINISHES SUCH AS TILE, WOOD OR VINYL GENERALLY REQUIRE ADDITIONAL ACOUSTICAL TREATMENT OR INSULATION TO MEET THE MINIMUM IIC REQUIREMENTS. THE FIRST ESSENTIAL FOR AIRBORNE SOUND ISOLATION USING ANY SYSTEM IS TO CLOSE OFF AIR LEAKS AND/OR FLANKING PATHS BY WHICH NOISE CAN GO THROUGH OR AROUND THE SYSTEM. SMALL CRACKS OR HOLES WILL INCREASE THE SOUND TRANSMISSION AT THE HIGHER FREQUENCIES. THIS CAN HAVE A DETRIMENTAL EFFECT ON THE OVERALL ACOUSTIC PERFORMANCE AND THE STC VALUE, PARTICULARLY FOR HIGHER ACOUSTICALLY RATED SYSTEMS. FAILURE TO OBSERVE SPECIAL CONSTRUCTION PRECAUTIONS CAN REDUCE THE EFFECTIVENESS OF THE PLANNED SOUND CONTROL METHODS. SYSTEMS SHALL BE AIRTIGHT. RECESSED WALL FIXTURES SUCH AS MEDICINE CABINETS, OR ELECTRICAL, TELEPHONE, AND TELEVISION DEVICES, WIRING, SPRINKLER PIPES, ETC., WHICH PENETRATE THE GYPSUM BOARD, SHALL NOT BE LOCATED BACK-TO-BACK OR IN THE SAME STUD CAVITY. ANY OPENING FOR SUCH FIXTURES AND FOR PIPING OUTLETS SHALL BE CUT TO THE PROPER SIZE AND SEALED. ELECTRICAL DEVICES SHALL BE INSTALLED IN FULL BOXES AND SEALED WITH A NON-HARDENING SEALANT, SUCH AS 3M BRAND FIRE BARRIER, MPP-4S MOLDABLE PUTTY PAD OR EQUAL. THE ENTIRE PERIMETER OF AN ACOUSTICAL ASSEMBLY SHALL BE MADE AIRTIGHT TO PREVENT SOUND TRANSMISSION THROUGH THE ASSEMBLY AND PREVENT SOUND FLANKING AROUND THE ASSEMBLY AND THROUGH ASSEMBLY PENETRATIONS. FLEXIBLE SEALANT OR AN ACOUSTICAL GASKET SHALL BE USED TO SEAL BETWEEN THE STC RATED ASSEMBLY AND ALL DISSIMILAR SURFACES AND ALSO BETWEEN THE ASSEMBLY AND SIMILAR SURFACES WHERE PERIMETER RELIEF IS REQUIRED. THE SPACING AND NUMBER OF MECHANICAL FASTENERS IS ALSO OF GREAT IMPORTANCE IN ACHIEVING A LISTED STC OR IIC RATING. PERIMETER SEALS IN WALL ASSEMBLIES: IN ORDER TO BE

ERE PERIMETER RELIEF IS REQUIRED. THE SPACING AND NUMBER OF MECHANICAL FASTENERS IS ALSO OF GREAT IMPORTANCE IN ACHIEVING A LISTED STC OR IIC RATING. PERIMETER SEALS IN WALL ASSEMBLIES: IN ORDER TO BE EFFECTIVE FOR THE LIFE OF THE BUILDING, SEALANTS MUST BE RESILIENT AND NON-HARDENING. STANDARD WEATHER CAULKING IS UNSATISFACTORY AS AN ACOUSTICAL SEALANT, SINCE IT TENDS TO HARDEN OVER TIME. PLACEMENT OF THE SEALANT IS CRITICAL. THE PURPOSE OF THE SEAL IS TO PROVIDE A RESILIENT CLOSURE BETWEEN ONE SIDE OF AN ASSEMBLY AND THE OTHER, WHICH REDUCES THE POTENTIAL FOR FLANKING NOISE TRANSMISSION. THE PREFERRED PROCEDURE IS TO INSTALL THE GYPSUM WALL BOARD WITH A MINIMUM 1/4" GAP BETWEEN THE ADJACENT CEILING GYPSUM PANEL AND ALSO AT THE SUBFLOOR. SEALANT SHOULD BE APPLIED TO FILL THE PERIMETER GAP BETWEEN THE GYPSUM WALL BOARD AND THE SURROUNDING FLOOR, WALL AND CEILING COMPONENTS. CAULKING SHOULD NOT BE PLACED BENEATH THE SILL PLATE OR RUNNER TRACK OF A WALL ASSEMBLY. INSULATION INDICATED TO BE PROVIDED IN A WALL ASSEMBLY SHALL BE THE SAME DEPTH AS THE WALL STUD FRAMING. UNLESS OTHERWISE REQUIRED BY CODE, REGULAR UN- FACED GLASS FIBER OR MINERAL WOOL INSULATION IS ACCEPTABLE. DO NOT OVERSTUFF THE INSULATION, AS THIS WILL REDUCE THE ACOUSTICAL PERFORMANCE OF THE ASSEMBLY. RESILIENT METAL COMPONENTS - RESILIENT CHANNELS SHALL BE DIETRICH RC DELUXE RCSD. RESILIENT CHANNELS POSSESS A SPRING ACTION TO DECOUPLE AND ISOLATE THE COMPONENTS THEY CONNECT, WHILE PROVIDING THE STRENGTH TO FIRMLY SUPPORT THESE COMPONENTS. A CONCERN IN THE INSTALLATION OF GYPSUM BOARD ON RESILIENT CHANNELS IS THE LENGTH OF THE FASTENER AND THE PLACEMENT OF THE FASTENER. THE FASTENER SHOULD NOT EXTEND INTO THE STUD OR JOIST, THUS SHORTING OUT THE RESILIENCY OF THE SYSTEM. AN EFFECTIVE INSTALLATION TECHNIQUE IS TO PLACE SCREWS ONLY BETWEEN STUDS OR JOISTS. THE CHANNEL MUST ALSO BE FREE TO FLOAT UPON INSTALLATION AND THUS A MINIMUM 1/4" INCH CLEARANCE BETWEEN IT AND THE ADJACENT ASSEMBLY IS REQUIRED. THE RESILIENT CHANNEL SHALL BE INSTALLED PER THE MANUFACTURER'S INSTALLATION INSTRUCTIONS. PIPES AND ELECTRICAL CONDUITS SHALL BE CONCENTRICALLY PLACED WITHIN WALL AND FLOOR/CEILING ASSEMBLIES, UNLESS OTHERWISE REQUIRED PER FIRE AND OTHER BUILDING CODES. REFER TO OTHER DRAWINGS, DETAILS AND SPECIFICATIONS FOR ADDITIONAL INFORMATION PERTAINING TO WALL AND FLOOR/CEILING ASSEMBLIES. THE FOLLOWING ITEMS
