Components

The protective value of the fabric composite is really found in the air that’s between the fire fighter and the heat source. Air itself is the greatest single source of the insulative qualities in protective clothing. Best of all, it weighs nothing and it’s free! The most functional way to achieve the best protection is to use a multi-layer configuration in which each layer accomplishes part of the job. It is logical that the thermal barrier systems which have the most air spaces can create the most layers of air or can resist absorption (water replacement of the insulation air) will provide the most reliable protection. Thermal barriers that use slippery yarns on the fire cloth are, also, less likely to bind and resist a fire fighter's movement.
