DuraDuct™ 2HR

ETL Listed ASTM E119 & CAN/ULC-S101 Fire Resistive Assembly

DuraSystems DuraDuct™ model 2HR is a direct code-compliant fire resistance rated solution.

The DuraDuct™ 2HR system design meets the requirements for a 2 hour fire resistance rating in accordance with the International Mechanical Code (IMC), International Building Code (IBC) and National Building Code of Canada (NBCC). The assembly is ETL listed, DSB/IMWP 120-01, providing a code  compliant, ASTM E119 and CAN/ULC-S101 shaft enclosure.

Shaft enclosures shall meet the code requirements of Section 703 in the IBC which requires ASTM E119 or UL 263 certification as well as the NBCC which requires CAN/ULC-S101 to determine the fire resistance rating.

When alternate materials and methods fall short of meeting the requirements of code prescribed fire resistance ratings, DuraSystems’ DuraDuct™ 2HR is the solution.
