The other components of a Starrco Pre-Engineered office, i.e. suspended ceiling, dust cover, steel door and windows, are noncombustible. Incorporating the DL panels into the office design will create a system in which all the components are noncombustible.
Starrco's standard (SP) panels consist of 1/8" vinyl covered hardboard (with Class C rating) laminated to both sides of a Class A polystyrene core.
Starrco's sound control (SC) panels are manufactured with all Class C substrate materials laminated to both sides of a Class A polystyrene core.
Fire ratings defined by a time limit (like one or two-hour fire rated) generally do not apply to Pre-Engineered offices. Rated walls are normally used to separate one area from another or to protect entrance and exit points between areas.
