Looking at the product data for two manufactures combustible concealed space sprinklers, they both seem to require that composite joist construction be filled with noncombustible insulation that is secured in place with metal wire. If I have a noncombustible concealed space that is of composite joist construction, but its not insulation filled, do I still use the CCS sprinklers, or do I revert back to a standard spray sprinklers?
