Product Features

Weather-Resistant Roof Penetration Seal

The DuraTech Storm Collar is required when installing DuraTech roof flashing to ensure a watertight seal around the chimney pipe. This aluminum collar diverts rainwater away from the pipe-flashing joint, helping to prevent leaks that could damage your roof or attic.

Durable Aluminum Construction

Manufactured from corrosion-resistant aluminum, this storm collar is built to withstand harsh outdoor conditions and high heat exposure from venting wood-burning appliances.

Secure Seal with High-Temperature Sealant

To complete the weatherproof seal, apply a non-hardening, high-temperature (rated to 500°F) sealant between the collar and the chimney pipe. This prevents water intrusion while allowing for slight movement during heating and cooling cycles.

Fits a Range of Chimney Sizes

Designed for use with 5", 6", 7", and 8" DuraTech chimney pipes. Each size accommodates an outer diameter that ensures a snug, reliable fit for your roof venting system.

Critical Chimney Component

A storm collar is not optional—it's required to ensure a complete and secure venting system when using any DuraVent roof flashing, whether on a pitched or flat roof. It plays a vital role in extending the life of your venting system and your roof.
