Every cover system in the C/S portfolio has a fire barrier assembly designed to work with it. These fire barriers are tested at UL to ensure full code compliance. Assemblies are available in standard 2-hour ratings but also 1,3 and even 4-hour ratings in some cases. Due to the high cost of UL tests, not all structural configurations have been tested. Some discretion may be needed to determine if a standard configuration applies in the case of a non-standard application. If in doubt, call the supplier and ask for additional testing to support your design. UL will normally accept small scale testing as an extension of an existing full-scale test and give it a rating.
