BASIC INFORMATION ON THE CLASSIFICATION OF FIREPROOF CONSTRUCTION PRODUCTS

The fire protection criteria for components such as the panels are determined by the international standard EN 13501-2.
The MCT panels are certificated as required by the Greek and international legislation, following this model and in particular on the basis of the following two criteria:

 

Fire Resistance (fire resistance acc. To EN 13501)

This criterion classifies construction products according 1.to the time required in order for  the flame to pass from the burning side to the non-burning one(integrity) and 2. so to develop either spot temperature above 180°K  or averaged 140 °K for the non burning sheet(Insulation).

The panels of MoT- Lava series and likewise the MoT -Optimum series have achieved the highest fire resistance times reaching up to 120min, both for Wall and Roof panels.

The tests conducted in accredited laboratories, with recognition across the European Union and the Middle East. Our certificates are accompanied by the appropriate certificate from the National Accreditation System (ESYD), which according to Article 14.3 of . 39112 F.701.2 order of A.P.S. deemed necessary for the approval of the certificate.

Reaction to fire (reaction to fire acc. To EN 13501)

This criterion classify construction products according to the gases emitted during the combustion, and accordingly the change in their structure during combustion.

All panels of MoT- Lava series, MoT -Optimum and MoT- ThermA1 are certified for their reaction to fire with the highest classification A1.
(** The test can not cover Acoustic series, since they  have a fleece)

This means that in case of fire the panels do not emit toxic smoke, and the structure does not exhibit defects such as creating drop and other particulate matter.

What is safety?

Fire safety is the set of practices intended to reduce the destruction caused by fire. Fire safety measures include those that are intended to prevent ignition of an uncontrolled fire, and those that are used to limit the development and effects of a fire after it starts.
Fire safety measures include those that are planned during the construction of a building or implemented in structures that are already standing, and those that are taught to occupants of the building.
Threats to fire safety are commonly referred to as fire hazards. A fire hazard may include a situation that increases the likelihood of a fire or may impede escape in the event a fire occurs.

The selection of the panels is very important in the design and construction . The stone wool panels with outstanding performance will not allow the fire to expand , do not emit toxic gases and accordingly to the cause of the fire, might prevent the upgrade to a devastating and unfortunately several times fatal incident.

In conclusion

The integrated fire protection solution requires combination of the fire resistance time and reaction to fire of the building elements.

Based on European statistics each year 4,000 people lose their lives and others 70,000 are hospitalized from fires. More than 50% of these cases- fatal and non-are caused from toxic fumes of combustion rather than the burn itself.

For the protection of human life,  environment and property  the most appropriate combination of both criteria is a must in order to ensure the construction of buildings and infrastructures the best conditions for timely and effective extinguishing of fire.
