Storm Collar


The storm collar slips around the pipe just above the flashing. Seal the inner edge to the chimney with non-hardening 500° high temperature sealant.

DuraPlus Chimney is a triple-wall, all-fuel chimney for use with wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, or other appliance fueled by wood, oil, coal, or gas. Each section locks tightly with a precision twist-lock connection. DuraPlus is designed to stay cool on the outside, to provide hot draft on the inside, to boost stove efficiency, and provide a fire-safe design that protects both the chimney and the building. This triple-wall chimney features two insulating layers (ceramic blanket, plus air space).
