United States

In the US, fire-safety expectations for ventilation systems are shaped by the International Building Code and NFPA standards, particularly NFPA 90A for ventilation systems and NFPA 92 for smoke control. 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.
