Fire-resistant components often need to be listed and labelled to relevant UL standards. Ventilation performance and energy efficiency are generally guided by ASHRAE 62.1 and ASHRAE 90.1. Elephant Duct’s flame-retardant materials support systems designed to satisfy NFPA-aligned safety requirements. Its dependable airtightness reduces leakage and helps ensure that designed airflow rates are actually delivered, supporting compliance with ASHRAE 62.1 and contributing to energy-efficient performance under ASHRAE 90.1.   ![cleaning elephant yeah](https://elephantduct.com/hs-fs/hubfs/cleaning%20elephant%20yeah.jpg?width=1024&height=683&name=cleaning%20elephant%20yeah.jpg) Why choose elephant duct ## Benefits Explore the practical benefits of Elephant Duct, from easier installation and flexibility to insulation, durability, and reliable ventilation performance.   [Learn more](https://elephantduct.com/benefits?hsLang=en) ![Elephant in the room](https://elephantduct.com/hs-fs/hubfs/Elephant%20in%20the%20room.jpg?width=1024&height=784&name=Elephant%20in%20the%20room.jpg) Compliance made simple ## Standards & Legislation Learn about the standards, classifications, and regulatory requirements that apply to ventilation ducting, and see how Elephant Duct meets the demands of modern installations.   [Learn more](https://elephantduct.com/standards-legislation?hsLang=en) Guides, Tools & Calculators ## Online tools from Elephant Duct ![25mm woolly mammoth compressed](https://elephantduct.com/hubfs/25mm%20woolly%20mammoth%20compressed.jpg) ### Duct Insulation Tool Interactive tool to help you decide which ducting thickness is right for your run, depending on the space and whether your air is temperature-controlled.
