As seen in Video 1 the presence of a barrier fabric can significantly delay fire growth and reduce peak fire size (HRR). The two barrier fabrics used in this video are inexpensive and commercially available. Barrier 4 (center) is a fiberglass fabric. Barrier 1 (right) is a rayon, cotton, and hydrated-silica fiber blend that is currently used to protect mattresses such that they can meet the requirements of 16 CFR Part 1633, the Federal Standard for the Flammability (open flame) of mattress sets.
