Could Fiberglass Reinforced Polymer materials be considered non-combustible? For this project it's intended to be used as an interior building material.
NFPA 130 & NFPA 101 definition of non-combustible material: 4.7 Non-combustible material A material that complies with any of the following shall be considered a noncombustible material [101:4.6.13.1].
Fiberglass Reinforced Polymer (FRP) materials can meet the following minimum standards for flammability:
Can this material be considered an equivalent to non-combustible material? While Fiberglass Reinforced Polymer (FRP) materials have an excellent fire resistance rating under ASTM and UL tests, it is not specifically classified as non-combustible under ASTM E136.

I have had limited experience with these materials, but one experience that is noteworthy is that they are not all made equal.

When I was studying at a University, I took a composites material course and lab. Fiberglass reinforced polymer is a type of composite material, in which epoxy or a similar resin is used to merge the fiber glass layer with the polymer. Epoxy is certainly combustible (and flammable before curing) but once it's cured it no longer produces vapors that can ignite.
