DuraVent DuraTech Storm Collar: a rain shield above the roof flashing
The DuraVent DuraTech Storm Collar is a cone shaped metal ring that clamps around the chimney above the flashing, the cover around the pipe at the roof. It directs rain away before it can run down the pipe and into the flashing. Every DuraTech flashing needs one, but the collar is sold separately. This collar is made of galvalume. Its inside edge needs a non hardening high temperature sealant where it meets the pipe. Choose the version for 5 and 6 inch chimney or the version for 7 and 8 inch 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. Between its stainless steel inner wall and galvalume or stainless steel outer wall sits an insulating blanket. That keeps the outside cool and heat inside to help draw smoke upward. This collar fits DuraTech only, not DuraPlus, DuraChimney, or another chimney line. Need the piece at the very top? See the DuraVent DuraTech Chimney Cap for the chimney top. The DuraVent DuraTech Storm Collar ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
