FIRE RESISTANCE

CERTIFIED REI 120 AND REI 240

BLOCKS AND FLOOR SLABS WOOD
CEMENT ISOTEX ARE RESISTANT TO FIRE AND WITH CERTIFICATION REI120 AND REI240

 

The fire resistance is a very important aspect for the buildings, to be taken into serious consideration in the design stage and when you buy the house. Among the various construction technologies there are some who, for their peculiarities defined “natural light”, ended up in ashes because of trivial electrical shorts or flues cutlery operates incorrectly. There are also other building technologies that use insulating blocks obtained with “petroleum products”, these construction technologies, in case of fire inside or outside of the structure, give off highly toxic gases that lead, as has already happened , serious poisoning.

For these important reasons, when you buy the house, you have to pay very attention not only to save energy, but also the behavior of the building materials in case of presence of fire. We therefore recommend that you always choose the materials that have obtained the certifications of resistance to fire REI.

 

ISOTEX offers maximum safety even in the aspect of fire resistance (REI 120 – REI240 without plaster) as the concrete and armor are within the mold block and so are protected from wood-cement; the wood is subjected to a natural mineralization process that makes it inert (inorganic) and therefore can not be attacked by fire, mold and parasites.

WHAT IT MEANS
CLASSIFICATION REI120 REI240?

It is an acronym used to indicate the fire resistance of a building element (component or structural):

  • R, it indicates the stability understood as the ability to retain their mechanical strength under the action of fire.
  • E, indicates the held of smoke as the ability to not let pass or produce (if submitted on the one hand to fire) vapors or hot gases on the unexposed side.
  • I, indicates the thermal insulation as an attitude to reduce within a certain time limit the transmission of heat.

The numbers following the letters are to indicate the minutes of stability, sealing and thermal insulation in case of fire.

TEMPERATURE DIAGRAMS

Very significant are the temperature diagrams (see photo) that demonstrate that the side of the wall and the floor where temperature sensors are located register 33°C after 180 minutes of fire exposure (of over 1.100°C) in the case of the blocks and 25°C after 240 minutes of fire exposure (of over 1.100°C) in the case of the floor slabs.

This exceptional fire resistance highlights two very important advantages:

  1. The building does not collapse in case of fire. The ISOTEX constructive elements, with reinforced concrete cores, retain their loadbearing capacity and insulation properties, without suffering damage.
  2. Thermally exceptional Excellent thermal insulation and inertia uneasily matched by other building systems.
