Fireproofing treatments

The objective of fire safety is to safeguard people and protect both goods and the environment. There is no doubt that, within the context of measures aimed at achieving the abovementioned objectives, passive protection plays an important and, in some cases, even decisive role.

The resistance to fire indicates the ability of an element to maintain certain characteristics in the presence of a fire for a predetermined length of time. These parameters regard the mechanical strength (R), the ability to not allow fire to pass through or produce flames, vapors or hot gases on the unexposed side (E) and the ability to reduce heat transmission (I). Of fundamental interest is the maintenance of the carrying capacity of a structural element even if all the other preventive measures taken are exceeded.

The main protectors that contribute significantly to fire resistance of structures are divided into passive protective coatings that remain inert during heating (plaster and slabs) and the reactive protective coatings subjected to heating, vary their physical state (intumescent or reactive paints).

The protective thickness to be applied is essentially determined on the basis of the physical and geometric features of the material to be protected, the load conditions to which the element is subjected, the fire load, the exposure and the critical temperature hypothesized, and finally the degree of fire resistance required.


Applying method: plastering machine
Protection level: R15 – R240
Supports: steel structures (open, round, hollow and box-like), corrugated sheets, concrete frames, concrete elements, wooden structures, masonry
Note: they’re usually used for structures that can’t be seen. They are resistant to atmospheric agents exposure


Applying method: mechanical fixing
Protection level: R30 – R360 EI 30 – EI240
Supports: steel structures (open, round, hollow and box-like), corrugated sheets, frames in general, concrete elements, wooden structures, masonry
Note: they can be used for making self-supporting septa, piping or ventilation systems. They have good resistance to atmospheric agents


Applying method: airless pump, rollers or brush
Protection level: R15 – R300
Supports: steel structures (open, round, hollow and box-like), corrugated sheets, frames in general, concrete elements, wooden structures, masonry
Note: products that are either solvent-based or water-based. With suitable protective and decorative varnish, they can be used outdoors. They can also be used for exposed structures without substantially altering the contour of the profiles treated.
