Very low smoke production
Smoke effects cause more casualties than the effects of the fire itself. The expandable graphite functions as a very efficient built-in smoke suppressant, with better results than any other known alternative fire-retardant system.
No toxic gas release and halogen-free technology
Carbon monoxide is a major toxic element in smoke development. In the event of fire prevENt membranes produce a very low percentage of carbon monoxide. prevENt fire performance technology is also halogen-free, therefore no toxic fumes from halogenated compounds are produced during application or in the event of a fire.
Reduces the dripping of the burning coating
The intumescent effect of the expandable graphite reduces the dripping of molten bituminous coating along the membrane.
Reduces heat release
The less heat that is released, the less the chance of a fast spreading fire, and the more time available for evacuation. prevENt membranes act as a very efficient fire retardant. The rate of heat release is half that of a standard polyester membrane and it has considerably better results than all known alternative fire retardant systems. |

Maintains primary waterproofing function
The waterproofing integrity and life expectancy of the roofing membranes remain completely unaffected as the polyester bases and coatings remain completely unaltered in fire-resistant form. |

Highest UK and European testing standards
prevENt membranes have been tested to the most stringent European standards, and have achieved the highest performance ratings in all sections of fire tests EN 1187 1, 2, 3 and 4 (BS 476: Part 3: 2004). |

Optimum safety in the event of fire, for man and the environment
prevENt membranes are not just another solution designed to meet the standards of fire test resistance. The prevENt range is above all a “safe” concept which significantly improves the safety of people during the evacuation of a building in the event of a fire, without releasing harmful smoke or toxic fumes into the environment. High performance and fire safety as standard
All prevENt membranes incorporating graphite technology meet LPCB requirements, yet still offer the highest level of waterproofing and life expectancy performance. So the specifier, the installing contractor and the building owner can be assured of the best all round waterproofing and fire performance protection. |
