Also Read: Differences Between DuraTech And DuraPlus Chimneys. DuraTech And DuraVent Chimney Features and Benefits Construction and Materials When it comes to chimney construction, material quality and durability should be top priorities. Both DuraTech and DuraVent use high-grade 316Ti stainless steel in their triple-wall chimney systems. This specialized alloy offers excellent corrosion resistance and can withstand temperatures over 2000°F. For stove pipes and connectors, DuraTech uses a 304 stainless steel material while DuraVent uses 430 stainless steel. Both offer good durability and heat resistance, but 304 stainless steel is a bit thicker-walled and more resistant to corrosion over time. Winner: Tie - both use high-quality stainless steel alloys, with DuraTech having a slight edge for connectors. Safety and Certifications DuraVent Chimney Proper safety certifications are also critical for any chimney system. All DuraVent and DuraTech chimney pipe is tested to UL-103 HT standards, ensuring it won't corrode or fail under high heat and acidic condensation. Their chimneys are also UL-103, UL-641, and UL-1777 tested for safety. When installed properly, both brands meet all chimney safety codes and standards. However, DuraVent does hold more third-party certifications overall for quality control and manufacturing consistency. Winner: Slight edge to DuraVent for its extensive third-party safety and quality control certifications. Design and Engineering DuraTech and DuraVent take slightly different design approaches for their stainless steel chimneys: DuraTech: Focuses on specialty chimney liners and a triple-wall chimney system with an insulated middle layer. Designed for easy DIY installation. DuraVent: Uses an air-insulated design in their DuraPlus triple-wall chimney for thermal expansion and contraction. Engineered for professional installation. DuraVent chimneys are also designed to withstand more thermal stress and extremes due to the air gap insulated design. DuraTech's solid insulation core can transfer more heat to the outer wall. Winner: DuraVent takes the edge for its innovative air-insulated chimney design. Ease of Installation When tackling a DIY chimney or stove pipe installation, ease of assembly and flexibility are big advantages. DuraTech wins when it comes to straightforward, DIY-friendly installation: DuraTech: Features twist-lock connections between chimney sections for quick, simple assembly. Triple-wall pipes are lightweight. Designed for DIY installs. DuraVent: Uses snap-lock chimney connections that take more skill to assemble. Galvanized outer pipe is heavy and awkward for 1-person installation. Usually installed professionally. DuraTech's lightweight chimney sections and twist-lock design allow easy DIY modifications and adjustments. DuraVent is engineered more for permanent professional installation. Winner: DuraTech for DIY-friendly design and lightweight simplicity. Product Range and Availability When choosing a chimney brand, it helps to have a wide range of venting and accessory options. Here's how the product lines stack up: DuraTech: Offers triple-wall chimney, double-wall stove pipe, and specialty liners. Accessories include shields, roof braces, flashing, and termination caps. DuraVent: Manufactures four chimney brands (DuraPlus, DuraTech, DuraBlack, PelletVent) and over 20 accessory options. From basic to luxury chimneys. While DuraTech covers the core essentials, DuraVent offers far more product diversity. You can find a specialized DuraVent chimney system for any install type, fuel, or budget. Winner: DuraVent for its wider chimney selections and extensive accessory options. Cost and Value The final factor that often determines which chimney brand to install is the cost and value balance. Here's how pricing shakes out: DuraTech: Offers affordable triple-wall chimney kits starting around $700. Budget-friendly for essential chimney needs. DuraVent: Chimney system prices range from $900 up to $2,200 or more. More expensive but high-performance. While DuraTech provides a solid product at an attractive price, DuraVent offers better value for money when you consider the advanced engineering and safety it provides. Pay a bit more upfront, gain much longer chimney life. Winner: DuraVent for outstanding value despite higher upfront costs. Also Read: Differences Between DuraVent And DuraPlus Chimneys.
