DuraVent FasNSeal Storm Collar: keeps rain out around the vent above the roof
The DuraVent FasNSeal Storm Collar is a collar that wraps around the vent just above the roof flashing, the piece that covers the roof opening. It directs rain away from the gap between the pipe and flashing. That keeps water from following the outside of the vent down into the roof. The collar slides down to rest on the flashing and is then sealed as needed. DuraVent requires one with every FasNSeal roof flashing. FasNSeal is DuraVent’s stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, built to carry pressurized exhaust and its acidic condensate outside.
Choose the collar size for your vent on this page, with sizes from 3 to 16 inch. The vent’s stainless steel construction includes welded seams. An experienced professional should handle the work, including fitting and sealing the collar at the roof. DuraVent also calls for a qualified inspector to check the whole vent each year. Have a double wall vent? See the DuraVent FasNSeal Storm Collar for W2, the double wall vent collar. The DuraVent FasNSeal Storm Collar ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
