7" DuraTech Chimney Cap is required where the chimney pipe terminates above the roof line. This Chimney Cap has removable screws to allow for easier cleaning of the chimney and spark arrestor screen. Includes spark arrestor screen.

6" DuraTech Storm Collar this aluminum storm collar is required for use on any through-the-roof installations using a roof flashing.

7" DuraTech Roof Flashing provides leak proof roof penetration. The purpose of the roof flashing is to weatherproof the roof where the chimney penetrates the roof. The flashing gets tucked under the shingles and the shingles are cut around the flashing if needed. The flashing is sealed to the roof with silicone to provide that needed seal to prevent water from getting under the flashing and getting into the attic or house, then a storm collar is placed over the flashing and sealed to the chimney pipe with a high temp silicone to prevent water from running down the chimney.

7" DuraTech Attic Insulation Shield is required for installations that pass through an attic to prevent insulation and debris from accumulating near the chimney. The Attic Insulation Shield fits over the Firestop Radiation Shield or Support box and consists of two-parts - a collar and a base.
