DuraVent DuraTech 7" Diameter Chimney Firestop
DuraVent DuraTech 7" Firestop
The DuraVent DuraTech 7" Firestop is a critical chimney safety component designed to maintain proper clearance where DuraTech 7-inch chimney pipe passes through ceilings or floor penetrations. Ideal for use with wood stoves, fireplaces, furnaces, boilers, and all-fuel heating appliances, this firestop enhances chimney fire safety, draft performance, and structural protection. Built within the advanced DuraTech double-wall chimney system, it ensures secure installation and helps maintain code-compliant venting system performance in residential applications.
Engineered with refractory insulation encased between dual walls, the DuraTech system delivers superior thermal efficiency by keeping the chimney’s outer wall cool while maintaining high flue gas temperatures for optimal draft performance. Its inner wall is 25% thicker than competing systems for added durability. Tested to strict UL 103HT standards, it withstands continuous operation at 1000°F, one hour at 1400°F, and three 2100°F chimney fire tests, ensuring long-lasting safety and reliability.
