E - durability
no flame
no smoke
high temperature
Strength (E) is the ability of a component or construction to maintain its strength on only one side of the element, without allowing the fire to spread to the unheated side as a result of the penetration of flames or hot gases.
EW - robustness and emission reduction
no flame
no smoke
lower thermal emissivity
Diffusion reduction (W) is the ability of a component or construction to maintain the rigidity of the element on one side only, reducing the possibility of significant thermal diffusion or the spread of fire through an element or from its unheated surface to adjacent materials.
EI - durability and insulation
no flame
no smoke
insulation against high temperature
Insulation is the ability of a component or construction to maintain its solidity on only one side of the element without allowing fire to spread as a result of a significant heat flow from a heated side to a non-heated side. During a fire, the construction on the unheated side reaches a maximum temperature between +140oC and +180oC.
