The attached You Tube video demonstration is a bit exaggerated as normally the role of a hearth rug is to protect various floorings from a popping ember or a small flying piece of coal jumping out of the stove past the fireproof hearth on to the floor or on to room carpeting, most often the popping ember or small flying coal will be there for a few seconds only until removed or someone puts its out, many times not causing any or very little visible damage. However the demonstration and its result is very valid as a supplemental protection instrument.
Personally we use a treated fire resistant wool hearth rug as it is extremely effective and far prettier, it does its job extremely well for us.
