The DuraPlus triple-wall chimney system is engineered for superior chimney fire safety, high-efficiency performance, and reliable all-fuel venting applications including wood stoves, fireplaces, furnaces, and boilers. Its advanced construction features **two insulating layers—ceramic refractory blanket and air space—**designed to keep the exterior cooler while maintaining a strong, efficient draft. The secure insulation eliminates hot spots common in loose-fill systems, ensuring consistent performance and enhanced chimney system durability.

Built for continuous operation at flue gas temperatures up to 1000°F, the DuraPlus chimney system meets stringent UL 103HT standards, including one hour at 1400°F and three 2100°F chimney fire tests. In the event of a creosote fire, the compressible insulation allows safe radial expansion, protecting both the chimney liner and structure for long-term residential chimney installation safety and performance.
