SOUND CONTROL DOOR ASSEMBLIES
10/06
NOTE: This specification covers the requirements for flush steel and wood sound
retardant doors with Sound Transmission Classification (STC) ranging from 25
to 45. Doors are limited to standard height and width where noise control is
required, relative to speech, music, office equipment, and general sounds
Sound retardant doors for complex and special applications, where noise control
related to machinery, industrial process sounds, automotive, and aircraft sounds
, are not included. Specification must be revised as required for the specific
application.
Sound retardant door assemblies include the door, perimeter seals, and metal
door frame.Some companies provide a complete guaranteed package consisting of
door, frame, special threshold, seals, gasketing,and hardware.
Drawings must indicate door locations, sound transmission classification ratings
required, UL label requirements, frame construction,fire and smoke ratings,
details of perimeter seals, and door bottom and vision panel requirements.

NOTE: Review Submittal Description (SD) definitions in Section 01 33 00 SUBMITTAL
PROCEDURES and edit the following list to reflect only the submittals required
for the project. Submittals should be kept to the minimum required for adequate
quality control.
A “G” following a submittal item indicates that the submittal requires Government
approval. Some submittals are already marked with a “G”. Only delete an existing
“G” if the submittal item is not complex and can be reviewed through the Contractor’s
Quality Control system. Only add a “G” if the submittal is sufficiently important
or complex in context of the project.
For submittals requiring Government approval on Army projects, a code of up
to three characters within the submittal tags may be used following the "G"
designation to indicate the approving authority. Codes for Army projects using
the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO"
for District Office (Engineering Division or other organization in the District
Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project
Office. Codes following the "G" typically are not used for Navy, Air Force,
and NASA projects.
Choose the first bracketed item for Navy, Air Force and NASA projects, or choose
the second bracketed item for Army projects.
Government approval is required for submittals with a "G" designation; submittals not having a "G" designation
are [for Contractor Quality Control approval.][for information only. When used, a designation following the
"G" designation identifies the office that will review the submittal for the Government.] Submit the following

1.3 COMPLIANCE, TESTING, AND GUARANTEE
NOTE: The three major U.S. testing organizations are (1) Intertek Testing Services
(Warnock Hersey), (2) Factory Mutual Research, and (3) Underwriters Laboratories.
Determine if the doors qualify with the standard frame. If neither the frame
nor the door is rated, a gasket system may be specified which will qualify the
door/frame assembly. Failure to do so will result in the door assembly not
qualifying for proper positive pressure labeling.
1.3.1 Compliance And Labeling
1.3.1.1 Category A Positive Pressure Fire Door Construction
Where requirements for positive pressure must be met, doors must include all requirements as part of the door
construction per Category A guidelines as published by ITS/Warnock-Hersey. No intumescent is allowed on the
frame. Only smoke gasketing applied around the perimeter of the frame to meet the "S" smoke rating is permissible
in instances where smoke control is required.
1.3.1.2 Category B Positive Pressure Fire Door Construction
All door openings must comply with the applicable portions of NFPA 101 and NFPA 252. Incorporate field applied
intumescent materials, applied by a licensed installer according to the manufacturers' instructions, which must
be kept on file. Additional gasketing may be required to meet the 'S' smoke rating. Submit Certificate for
Intumescent Seals, Gasketing[ and Door Bottoms].
1.3.1.3 Labeling
All positive pressure door assemblies must carry the fire label for the complete opening, clearly identifying
the:
a. Manufacturer
b. Third party testing and certification agency
c. Fire door rating
d. Installation limitations
e. Compatible frame, hardware component ratings
f. Compatible lite or vision panel component ratings
g. Required building code information, including temperature and smoke rating.
1.3.2 Testing
1.3.2.1 Sound Transmission Classification (STC)
Provide Test reports prepared by a nationally recognized, independent laboratory for Acoustical Tests, Air Infiltration
Tests,Wind Loading Tests, and Water Leakage Tests indicating that the sound transmission classification (STC)
of the proposed door, based on tests at 16 third-octave band frequencies from 125 to 4,000 hertz, is no less
than the specified STC when tested in accordance with ASTM E 90, and that the door tested is hung in substantially
the type of wall and frame as indicated and is fully operable with hardware and perimeter seals installed.
1.3.2.2 Positive Pressure
Provide Test reports, prepared by a nationally recognized, independent laboratory for Positive Pressure Tests,
for all fire rated door assemblies, including Intumescent Seals,Gasketing[, and Door Bottoms].
1.3.3 Guarantee
Provide written guarantee that each door delivered to the project is equal in construction, sound transmission
classification (STC), and positive pressure test rating where applicable, with appropriate labeling and markings,
to that of the sample door tested. Clearly state in written guarantee that each door assembly, when installed
in accordance with the manufacturer's printed instructions, will have an in-place STC within 3 decibels of the
specimen tested. Submit the following test data and Certificates with the written Guarantee:
Wind Loading Tests
Water Leakage Tests
Acoustical Tests
Air Infiltration Tests
Positive Pressure Tests
1.4 DELIVERY, HANDLING, AND STORAGE
Ship all doors in the manufacturer's undamaged individual cartons, securely bundled and wrapped with moisture-resistant
covers and stored in accordance with the manufacturer's printed instructions in a dry, clean, and ventilated
area.
Deliver and store wood doors in the building following the installation of concrete, terrazzo, plaster, or other
wet materials, and only after the building has dried out and has a roof.
Maintain relative humidity in the building between 30 and 65 percent. Maintain the ambient temperature at 16
degrees C 60 degrees F minimum at the time of installation of wood doors.
Make final adjustment of seals when temperatures and humidity conditions approximate the interior conditions
that will exist when the building is occupied.
1.5 FIELD MEASUREMENTS
Filed verify all measurements prior to preparation of drawings and fabrication.
