FireSmart capsheets provide a fire protection layer, shielding the roof from both spread of flame and fire penetration


How The FireSmart Roofing Systems Works

Most roofing materials will produce an exothermic reaction when subjected to heat. An exothermic reaction is a chemical reaction that is accompanied by the release of heat. In other words, the energy needed for the reaction to occur is less than the total energy released. As a result of this, additional energy is released in the form of heat. This additional energy will cause burn temperature to increase.

When a flame comes into contact with the surface of the FireSmart cap sheet, the presence of volcanic rock brings about an endothermic reaction within the membrane.

Heat is actually drawn from the flame to support a process of carbonisation in the cap sheet, so reducing the burn temperature. The resulting unbroken carbonised ‘shell’ then seals off combustible material beneath, denying the already-weakened flame further fuel and preventing any further combustion.

In the video below you can see the outstanding protection that Icopal's FireSmart system provides.
