DuraVent DuraTech Pass Through Radiation Shield: for a chimney coming through the ceiling from below
The DuraVent DuraTech Pass Through Radiation Shield is a shield for a chimney passing through a ceiling from below. It goes above a factory built fireplace where the chimney begins on the fireplace, not at a ceiling support box. The bottom includes a firestop, a barrier at the ceiling opening. The top can also serve as the attic’s shield against chimney heat. Its height adjusts from 24 to 36 inches. Choose a 6, 7, or 8 inch diameter to match your chimney.
DuraTech is DuraVent’s double wall chimney, an insulated pipe with a 1 inch wall that takes over from the stovepipe at the ceiling or wall and runs up past the roof. An insulation blanket separates its stainless steel liner from its galvalume or stainless steel exterior, keeping heat inside for draft while the outside stays cooler. A straight chimney needs at least 10 to 15 feet above the stove outlet. Its cap must sit 3 feet above the roof exit and 2 feet above anything within 10 feet. Starting at the ceiling? See the DuraVent DuraTech Square Ceiling Support Box. The DuraVent DuraTech Pass Through Radiation Shield ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
