Key Differences Between Selkirk And DuraVent Chimney
Now that we’ve got an overview of both brands, let’s dive deeper into how they compare across some key factors:
Durability and Construction
The durability and longevity of the chimney system depends on the materials and construction quality. This is important to prevent corrosion and withstand high flue temperatures over many years.
- Materials
When it comes to materials, both Selkirk and DuraVent use premium grade 316Ti stainless steel in their chimney constructions. This type of stainless steel has excellent corrosion resistance and can handle continuous temperatures up to 2100°F.
Selkirk offers 316Ti stainless steel across all their chimney lines from Standard to ULTIMATE. DuraVent reserves the 316Ti stainless for their top-tier DuraTech chimney while using 304 stainless steel for models like DuraPlus.
- Construction
In terms of construction, Selkirk and DuraVent both utilize similar double-wall insulated designs.
This helps maintain flue temperatures and improve draft.
However, Selkirk uses a unique twist-lock connection method for their chimney joints instead of securing with screws or rivets.
This twist-lock design allows for quick and secure connections while also accommodating for expansion and contraction.
DuraVent chimneys feature a positively locked riveted system and their DuraTech line has an extra interlocking joints feature for added mechanical strength.
- Insulation
For insulation, Selkirk chimneys are packed with high-temperature ceramic wool insulation able to withstand temperatures up to 2100°F. DuraVent also uses a 1″ ceramic fiber wrap insulation rated for 1800°F continuous use.
- Wind Resistance
Both brands test their chimneys to resist winds up to 140 mph. Selkirk’s locking bands and unique offsets enhance wind resistance. DuraTech connectors have a positive locking system and strategically placed embossed tabs for a tight interlocking fit to prevent unwinding.
- Lifespan
With quality stainless steel construction and insulation, both Selkirk and DuraVent chimneys are built to last decades. Selkirk offers a limited lifetime warranty while DuraVent provides a 15-year warranty, reflecting their durability claims.
The Winner: Tie
It’s a close call between Selkirk and DuraVent for durability. Both utilize 316Ti stainless steel and ceramic insulation. Selkirk’s twist-lock design offers quick, secure connections while DuraVent has reinforced interlocking joints. Either brand is a good long-term option.
Efficiency and Performance
A key role of any chimney is maintaining proper draft for optimal efficiency and performance. This results in complete combustion, less smoke and reduced creosote buildup. Let’s see how Selkirk and DuraVent chimneys stack up in terms of efficiency.
- Draft Performance
The draft is directly affected by the inner wall flue size so having optimal dimensions is crucial.
Selkirk chimneys are available in a range of diameters from 6″ to 16″ to match any appliance. Their Ultamate and Super Pro lines have a 2″ thick insulation layer to enhance draft performance.
Similarly, DuraVent provides a selection of flue diameters ranging from 4” to 16”. Models like DuraTech have a 2” insulation for improved draft while DuraPlus HTC uses 1” insulation.
- Fire Safety
In terms of fire safety, both chimney brands are tested and listed to UL standards. The dual-wall construction prevents flue temperatures from exceeding thresholds.
Selkirk chimneys are tested to UL-103 HT standards for 2100°F safety. DuraVent chimneys meet UL-103 up to 1800°F.
- Rain Caps
Proper rain caps prevent water and pests from entering the chimney system. Selkirk and DuraVent offer a variety of cap options from standard to deluxe versions.
- Creosote Handling
Creosote accumulation and cleaning access is another consideration. Selkirk’s unique twist-lock design enables easy interior access for inspection and cleaning. DuraVent offers straight or offset tees to simplify creosote removal.
The Winner: Tie
When it comes to efficiency and performance, Selkirk and DuraVent once again are evenly matched. Both offer optimal draft flue diameters and fire-resistant construction.
Selkirk provides easy cleaning access while DuraVent has specialized tee options. Overall, either brand will deliver reliable chimney performance.
Safety
Safety is the number one priority when dealing with chimney systems. Let’s explore how Selkirk and DuraVent chimneys stack up when it comes to safety features and certifications.
- Safety Standards
We touched on this earlier, but to recap – both brands meet UL 103 safety standards in the US and ULC S604 in Canada for factory-built chimneys.
Selkirk chimneys are tested to UL-103 HT standards, allowing for use with 2100°F flue temperatures. DuraVent meets UL-103 for 1800°F.
- Clearances
For clearances, Selkirk recommends 2” minimum air space clearance to combustibles, which can be reduced with additional shielding. DuraVent also recommends 2” combustible clearance for many of their models. Always follow the manufacturer’s specifications.
- Installation
Proper installation is key to safety. Selkirk provides detailed installation instructions for each chimney kit. DuraVent also offers product-specific installation manuals and training. Using a certified professional installer is recommended.
- Free-standing vs Wall-mounted
Selkirk offers both free-standing and wall-mounted chimney options while DuraVent focuses more on wall-mounted. The free-standing design avoids cutting holes in walls that could violate fire codes.
- Code Compliance
Both companies design chimneys to meet the relevant building codes. However, be sure to check local regulations for any additional requirements. Improper installation can result in code violations and safety hazards.
The Winner: Selkirk
For prioritizing safety, Selkirk edges out DuraVent as the winner in this category. Their UL-103 HT 2100°F rating, free-standing options, and detailed installation guidance give Selkirk the advantage. However, both brands meet stringent safety standards when installed properly.
