A next-generation solution in cementitious passive fire protection (PFP), Carboline’s high-density, exterior-grade Pyrocrete 341 product meets the rigorous exposures of hydrocarbon fire, jet fire and cryogenic spill protection—all at a single thickness, with zero erosion factors.
The most extensively tested cementitious fireproofing product in the industry, Pyrocrete 341 is UL 1709 rated for up to four hours of hydrocarbon fire protection and 30-120 minutes of jet fire resistance. This offers facility owners, engineering construction firms and applicators a single solution to meet all PFP key performance design criteria for long-term asset protection. Combined with Pyrocrete 341’s ultimate durability and rapid set time, this results in significant cost savings and throughput advantages over competitive cementitious products.
The development of Pyrocrete 341 strengthens Carboline’s existing portfolio of cementitious fireproofing solutions. It is manufactured using only the highest-quality raw materials, with strict QA/QC protocols under the UL follow-up service.
