noncombustible
Resistant to flames
Noncombustible describes materials that will not catch fire or burn under normal conditions: noncombustible building materials, a noncombustible storage container.
The term appears most often in building codes, fire safety regulations, and industrial specifications.
Concrete, brick, and steel are noncombustible; wood and fabric are not.
