The Fardtry storm collar is constructed from galvanized steel, offering water and rust resistance for outdoor use. It features a large 3.94″ width and a smooth surface designed to deflect rain away from roof flashing, aiding efficient drainage. The collar uses adjustable stainless steel clamps allowing the top diameter to be set between 7.48″ and 8.26″, making it compatible with most 6″ double wall pipes or 8″ single wall pipes. This versatility supports a range of chimney configurations while maintaining a robust seal against weather.
Fireside Chimney Supply Storm Collar – 12in
Fireside Chimney Supply offers a straightforward storm collar option designed to seal above the roof flashing. While the product listing emphasizes its role as a storm collar, users should verify fitment with their chimney pipe diameter to ensure a proper seal. This collar provides a cost-effective solution for weatherproofing around chimney penetrations in outdoor environments.
Selkirk Metalbestos 8T-SC Storm Collar
Selkirk’s 8T-SC storm collar is designed for 8-inch diameter piping and is fabricated from stainless steel (28 gauge). This steel construction offers strong corrosion resistance and durability against weather exposure. The collar is positioned just above the roof flashing and typically requires waterproofing at the upper edge to prevent water intrusion between the collar and chimney pipe, especially in areas with heavy rainfall.
Selkirk Metalbestos 6T-SC
This 6-inch stainless steel storm collar from Selkirk is designed to fit round chimney pipes just above roof flashing. Proper installation includes waterproofing the upper edge with plastic sealer to prevent water from seeping between the collar and chimney pipe. The part is secured with screws or tabs after positioning to maintain a tight seal and durable fit under winter conditions and heavy rain.
DuraVent 288006 Storm Collar
The DuraTech storm collar slips around the pipe just above the flashing, with an inner edge sealed to the chimney pipe using a non-hardening 500-degree Fahrenheit high-temperature sealant. Constructed from aluminum, this collar is built to resist outdoor elements while providing a secure seal against moisture intrusion around the chimney-flashing interface. Its design emphasizes compatibility with high-temperature chimney systems and straightforward installation.
AllFuel HST Storm Collar for 6″ Diameter
AllFuel HST’s storm collar for 6″ diameter AllFuel Class-A double-wall chimney pipe is made from 304 stainless steel, offering strong corrosion resistance. The collar is designed to be installed above flashing to seal the installation and keep water out. This option is specifically tailored to AllFuel HST Class-A systems, ensuring reliable compatibility and a corrosion-resistant solution for long-term outdoor use.
Buying Guide: Key Purchase Considerations for Storm Collars
- Compatibility with chimney pipe size: Confirm the collar diameter matches or is adjustable to your pipe type (double-wall, single-wall, Class-A, etc.).
- Material durability: Stainless steel offers superior corrosion resistance, especially in harsh climates, while galvanized steel and aluminum can be adequate for moderate exposure when properly protected.
- Weather sealing and installation: Look for a model with a robust sealing method and straightforward mounting. Some collars include adjustable clamps; others require sealants at the upper edge.
- Roof flashing integration: Ensure the collar sits flush above the flashing and provides a reliable rain deflection angle to minimize water ingress.
- Thermal and high-temperature considerations: For high-heat chimneys, select collars rated for appropriate temperatures and with sealants designed to endure heat.
- Maintenance and longevity: Stainless steel options typically offer longer service life with less corrosion, especially in coastal or salted environments.
- Installation notes: Some collars require waterproofing at the top edge or use of additional sealants; factor in DIY vs. professional installation needs.
- Brand reliability and warranty: Choose reputable brands with documented performance and available replacement parts.
In summary, the best storm collar choice depends on your chimney’s size, exposure to weather, and the material that best fits your system. The options reviewed here balance durability, ease of installation, and compatibility across common American chimney configurations.
