Precision-Engineered, Pre-Insulated Duct—Now Spooling in Lengths Up to 25 Feet

 

EnduraDuct continues to push the boundaries of efficiency and performance in outdoor HVAC systems. Our insulated ductwork is now available in continuous spooled sections up to 25 feet—dramatically reducing onsite labor, installation time, and potential leak points.

Each section features:

  • SMACNA-standard metal interior for strength and code compliance

  • High-performance insulation with R-values up to R-33.29+

  • Proprietary hard-shell exterior coating: chemical, mold, UV, and weather resistant

  • Fully washable, corrosion-free shell ideal for rooftop and exposed environments

  • ASTM-tested performance: Shore D Hardness ≥ 50, Tensile Strength ≥ 3100 psi, Elongation ≥ 500%, and more

  • Indoor-use compliant under IMC 604.3 Exception 2

This next-gen spooling capability minimizes joints and enhances long-run integrity—making EnduraDuct the go-to solution for engineers, contractors, and facility managers focused on durability, energy efficiency, and clean air delivery.

Chemical & Saltwater ResistanceEnduraDuct's exterior coating isn't just tough—it’s been rigorously engineered and lab-tested to perform in environments where most coatings fail.Our 100% solids elastomeric membrane resists a wide range of industrial chemicals and corrosive agents, forming a seamless, non-permeable shell that protects against degradation from:AcidsSolventsAlkalisDisinfectantsSalt-laden air and waterTested under salt fog and chemical exposure conditions, EnduraDuct’s coating maintains its integrity and performance in: Coastal climates with high salt spray exposure. Industrial zones with chemical emissions and airborne contaminants, Wastewater and processing environments where corrosion risk is extreme. With a Shore D hardness of ≥ 50 and tensile strength ≥ 3100 psi, the coating is highly resistant to physical wear while remaining flexible—ideal for rooftop ductwork, curb caps, and metal components exposed to the elements. Where corrosion is common, EnduraDuct is the uncommon solution.
