FireStrong fire-rated FRP strengthening products consist of high-temperature reinforcement and durable, rigid thermal protection boards. The reinforcement has an operating temperature of 400°F. The FireStrong System is ideal for use in high heat environments or in structures where the FRP is required to resist forces for the duration of the fire. The thermal protection boards may be used with RenewWrap FRP systems where the objective is to simply protect the existing substrate.
