Jun 2, 2009 I'm not a carpet expert but it's amazing how much information you can find online. It turns out that the IBC and NFPA 101 both require floor coverings that comply with NFPA 253 Class I or II (Class I is less flammable than Class II) in locations where fire rated openings would be found, so a threshold would

Wood by nature is a flammable material. The tunnel is calibrated to an index of 0 for non-combustible materials and 100 for red oak flooring plank. Class F & Class E are tested in accordance to EN ISO 11925-2: Reaction to fire tests – Ignitability of building products subjected to direct impingement of flame – Part 2:
The most commonly used flame-spread classifications are: Class I or A, with a 0-25 FSR; Class II or B with a 26-75 FSR; and Class III or C with a 76-200 FSR. In general The most widely accepted flame-spread classification system appears in the National Fire Protection Association Life Safety Code, NFPA No. 101.
Products classified in a given class are deemed to satisfy all the requirements of any lower class. Products classified in A1 and A2 classes are non-combustible (cement, concrete, minerals, glass, fiberglass, rock wool, ceramic, etc.), materials certified from B to F are combustible in ascending order.
