DuraVent DuraFlex Stainless ProMesh: a mesh sleeve that protects the liner’s insulation blanket
The DuraVent DuraFlex Stainless ProMesh is a sleeve of 304 stainless steel mesh that covers a chimney liner wrapped in ProFoil insulation. It helps keep the blanket from tearing as the liner is lowered into the chimney. Pulling the mesh along its length makes it tighten around the blanket. A stainless band clamp secures each end, and those clamps are sold separately. DuraFlex Stainless is DuraVent’s flexible stainless steel liner for relining a masonry chimney that vents a wood, pellet, oil, or gas appliance. These include home stoves, fireplace inserts, furnaces, boilers, and water heaters.
The blanket and mesh go on before the liner goes into the chimney. The blanket is laid foil side down, wrapped around the liner, and taped along the seam before the mesh slides over it. The blanket and tape are sold separately. Choose small for 3 to 6 inch liners, large for 7 to 9 inch liners, or extra large for 10 to 12 inch liners. Each size is 25 feet long. Need tape for the blanket seam? See the DuraVent DuraFlex Stainless AluFoil Tape for blanket seams. The DuraVent DuraFlex Stainless ProMesh ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
