1. Lie - Fire rated tile, unless it is ceramic or metal it is not fire rated. But many claim their tile is fire rated because they got the entire assembly fire rated, but the tiles were gone in 5 minutes.
2. Some claim to be first with Water Proof Ceilings, it is a lie, each one that has claimed that bought from China, in the USA there are many even older than those.
3, Class A Lies, I know of 2 companies that claim they are class A by ESTM A 84 but problem is it is in fire index and not smoke spread that they got their rating, which means they are not Class A, not Class B or Class c, their products can only be used outdoors. But they are in VA hospitals, Schools, other Hospitals, Wal Mart, and more.
