The DuraChimney II Storm Collar is designed to help prevent rain and moisture from entering the chase around the chimney pipe. Installed in conjunction with a flashing and chimney cap, it forms a weather-resistant seal for added protection and long-term performance. Ideal for maintaining a watertight system in all weather conditions.
Additional Durachimney II Info:
DuraChimney II offers a high-performance, factory-built alternative to traditional masonry chimneys. Its unitized, lightweight construction eliminates the need for field assembly of pipe sections, making installation faster and more efficient. Engineered with a double-wall, air-cooled design, DuraChimney II stays cool on the outside while maintaining a strong, hot draft on the inside. This fire-safe system is built to protect both the chimney and the structure. It allows for thermal expansion in all directions under high heat and is tested to UL 103 standards—approved for continuous operation at 1000°F, one hour at 1400°F, and ten minutes at 1700°F.
