Description
Elevate your chimney experience with the DuraVent DuraTech 8" Galvalume Steel Chimney Pipe. When it comes to safety, performance, and installation ease, this chimney pipe is second to none.
Crafted for Excellence: DuraTech is not just any chimney pipe; it's a masterpiece of engineering. With a Thermal Tech blanket insulation tucked between double walls, it ensures your chimney's outer wall remains cool while delivering high flue gas temperatures for optimal draft performance. In addition to this, the inner wall is a solid 25% thicker than the competition, providing that extra margin of safety that's crucial in any installation. Say goodbye to locking bands and mechanical fasteners; DuraTech simplifies the process with its sleek 1" wall design, making installations through 16" on-center framing a breeze.
Designed for Endurance: DuraTech isn't just about ease; it's about resilience. It's designed for continuous operation at flue gas temperatures of up to 1000°F. But we didn't stop there; it goes through rigorous tests, including an hour at 1400°F and three ten-minute chimney fire tests at 2100°F. Your safety is our priority, and DuraTech proves it.
Effortless Installation: DuraTech's ingenuity extends to its installation process. For tight spots, consider the Reduced Clearance Square Ceiling Support Box designed exclusively for 6" diameter DuraTech. It's a testament to our commitment to making your installation as smooth as possible.
