DuraVent DuraTech Chase Top Flashing: a ventilated cover for the chimney enclosure
The DuraVent DuraTech Chase Top Flashing is a galvalume metal cover for a chase, the boxed in enclosure around an outside chimney. It covers the top around the pipe. Included spacer clips leave a gap underneath so air can escape from the enclosure. A storm collar fits around the pipe above this cover and is sold separately. 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.
Choose a 5, 6, 7, or 8 inch diameter to match your chimney. The opening is 3 inches wider than the chimney, and the chimney cap needs to sit at least 6 inches above the cover. This part fits DuraTech only, not other chimney lines. With its thin insulated wall, a 6 inch DuraTech chimney measures 8 inches outside and fits between rafters spaced 16 inches apart without changing the framing. Need the vent for the bottom? See the DuraVent DuraTech Chase Air Intake with Rodent Guard bottom vent. The DuraVent DuraTech Chase Top Flashing ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
