In the event of a fire, an untreated joist’s web burns through about 70% faster than its top and bottom chords. With a compromised web, the joist cannot support the intended load. Add evacuation time and peace of mind with ProTEKtor IIJ®.
ProTEKtor IIJ® Fire-Rated joists are evaluated to meet code requirements for fire-resistant construction.
Specifically designed for harsh climates. ProTEKtor IIJ® binds to the surface of the wood to form a tough and durable coating, protecting joists from potential fire threats.
