Boost your chimney's performance and safety with the DuraVent DuraPlus Stainless Steel Tee. In the world of chimney systems, DuraPlus stands as a pinnacle of quality and innovation. This triple-wall chimney component is meticulously engineered to offer superior performance and uncompromising safety, making it the preferred choice of homeowners and professionals alike.

At the heart of DuraPlus lies a commitment to excellence. It features two insulating layers, including a refractory blanket and an air space, ensuring that your chimney stays cool on the outside while providing a hot draft on the inside. This ingenious design not only enhances stove efficiency but also shields both the chimney and your precious building from potential fire hazards.

In the unfortunate event of a creosote fire, the compressible blanket insulation allows the chimney liner to expand outwardly, minimizing damage and risks. DuraPlus doesn't just meet industry standards; it exceeds them. It's tested rigorously under UL standards, enduring extreme conditions, including one hour at 1400°F and three ten-minute chimney fire tests at a blistering 2100°F.
