DuraDuct 4HR

4-Hour Fire Rated Duct

DuraDuct™ 4HR is the only 4-hour fire rated duct system on the market.

DuraDuct™ 4HR is a single source 4-hour fire rated, zero clearance ventilation duct system ideal for applications when the highest degree of fire protection is required. The DuraDuct™ 4HR provides the flexibility you need to get the job done right. Once the DuraDuct™ 4HR is installed, the fire rating is achieved immediately without the need for any additional treatment of the duct.

The DuraDuct™ 4HR system is easily inspected as the pre-fabricated design eliminates the need to closely monitor the site installation variables so often found with wrap and enclosure type systems.
