Three minutes or 180 seconds - during this time, the fire becomes life-threatening.
Thirty years ago, the average house needed 17 minutes for the flames to completely engulf the building.
Studies show that on average, a house burns in just 3-4 minutes due to modern synthetic building materials and home furniture. A fire in a hotel, apartment building or commercial building made of steel, concrete, glass and other dense materials is a much more serious problem. These design features can hinder or block mobile radio communications, disrupting communication with the main rapid response services. A delay in communication can mean the loss of valuable seconds.
Modern challenges require modern solutions!
Therefore, a very important role is played by the choice of materials according to the group of flammability and that the material is at the same time environmentally friendly and free of harmful impurities.
What is the flammability group, we will consider below
Flammability is the ability of substances and materials to ignite themselves, as well as to ignite under the influence of an ignition source.
Combustible building materials are divided into the following groups
- low-flammable (G1), having a flue gas temperature of no more than 135 degrees Celsius, the degree of damage along the length of the test sample no more than 65 percent, the degree of damage by the mass of the test sample no more than 20 percent, the duration of self-combustion is 0 seconds gorenje
- gorenje-flammable (G2), having a flue gas temperature of no more than 235 degrees Celsius, the degree of damage along the length of the test sample no more than 85 percent, the degree of damage by the mass of the test sample no more than 50 percent, the duration of self-combustion no more than 30 seconds
- normally flammable (G3), having a flue gas temperature of no more than 450 degrees Celsius, the degree of damage along the length of the test sample is more than 85 percent, the degree of damage by the mass of the test sample is not more than 50 percent, the duration of independent gorenje is not more than 300 seconds
- highly flammable (G4), having a flue gas temperature of more than 450 degrees Celsius, the degree of damage along the length of the test sample is more than 85 percent, the degree of damage by the mass of the test sample is more than 50 percent, the duration of independent gorenje is more than 300 seconds
At the same time, for materials belonging to the combustibility groups G1 - G3, the formation of burning melt drops during the test is not allowed (for materials belonging to the combustibility groups G1 and G2, the formation of melt drops is not allowed). For non-combustible building materials, other fire hazard indicators are not determined and are not normalized.
The flammability groups are defined for building materials that are mounted vertically. Such a property of building materials as combustibility is crucial when a fire spreads through vertical structures.
Armacell uses a whole range of fire extinguishing additives for the production of materials.
Therefore, the finished products do not support independent gorenje gorenje and do not spread a flame on the surface, and are also characterized by low toxicity of combustion products and low smoke generation, which allows them to be used at facilities with increased fire safety requirements.
You can buy Armacell products in sheet form or in the form of cylindrical tubes.
