Thermal Barrier Exception

The International Code Council (ICC) is responsible for the International Building Code (IBC).  According to IBC section 2603, foam-filled building products, such as walls and doors, must use an approved thermal barrier between the foam and the interior of the building. But there are exceptions.  When the door need not be fire rated, it must pass related tests to qualify for an exception.  Recently, we put three of our doors through the tests performed by the ICC Evaluation Service. All three doors (SL-17, SL-19-1, SL-20) met the test requirements which evaluated the following door properties:

  • surface-burning characteristics
  • wind resistance
  • durability

Thus, ESR-1669 was re-issued in December 2017 for these products.
