The DuraVent DuraPlus 7" x 36" Chimney Pipe is a premium triple-wall chimney system component designed for safe, efficient venting in wood stoves, fireplaces, furnaces, boilers, and all-fuel heating appliances. Its advanced refractory blanket insulation and air-space design keeps the outer wall cooler while promoting a strong, consistent draft for improved heating efficiency. This chimney pipe system eliminates hot spots common in loose-fill insulation, enhancing chimney fire safety and protecting both the structure and venting system in residential installations.

Built for continuous operation at flue gas temperatures up to 1000°F, the DuraPlus 7" x 36" chimney pipe meets strict UL 103HT standards, including one hour at 1400°F and three 2100°F chimney fire tests. This durable all-fuel chimney pipe delivers long-lasting reliability, superior thermal performance, and code-compliant installation for modern chimney systems.
