How Tough is DuraDuct?

We knew DuraSystems products are well built, but we had no idea! We depend on DuraDuct™ KEX and DuraDuct™ SED in particular for grease duct installations, since they are the largest no weld, UL Listed kitchen exhaust duct systems in the industry. We appreciate the precision and dependability of pre-manufactured venting, and we know it reduces installation costs while providing superior fire protection. But check out this video of DuraDuct surviving rigorous UL testing!

  • DuraDuct KEX is rated for two hours fires resistance with zero clearance to combustibles.
  • DuraDuct SED is a pre-manufactured, single wall kitchen exhaust duct system, rated for 18” clearance to combustibles.

Both systems are fully compliant with the requirements of the International Mechanical Code (IMC), National Building Code of Canada (NBCC) and National Fire Protection Association (NFPA) codes.
