Styrofoam Sound Barrier
The Styrofoam™ sheets applied to the walls of this mechanical room being use as a sound barrier must meet the interior wall and ceiling finish requirements of the 2000 edition of NFPA 101®, Life Safety Code®. For Health Care Occupancies Section 19.3.3.2 states the following:
19.3.3.2 Interior wall and ceiling finish materials
complying with 10.2.3 shall be permitted as follows: (1) Existing materials — Class A or Class B. Exception: In rooms protected by an approved, supervised automatic sprinkler system, existing Class C interior finish shall be permitted to be continued to be used on walls and ceilings within rooms separated from the exit access corridors in accordance with 19.3.6.
It is expected that this type exposed product for this application will not meet the interior finish requirements.
