Which of the following is NOT listed as a common sprayed fireproofing product?

Sprayed fireproofing is meant to protect structural steel by slowing heat transfer and maintaining strength during a fire. The common types you’ll see listed are cementitious spray-applied, mineral wool spray, and intumescent coatings. Cementitious spray-applied material is easy to apply, affordable, and provides a solid protective layer. Mineral wool spray uses noncombustible rock or slag wool with excellent fire resistance and low heat transfer. Intumescent coatings are paint-like products that react to heat by swelling and forming a protective char to shield the steel. Fiberglass spray coatings, on the other hand, are more associated with general insulation rather than fireproofing and often don’t meet the fire-rating requirements reliably, plus issues like fiber shedding can be problematic. For those reasons, fiberglass spray coatings aren’t listed as a common sprayed fireproofing product.
