Fire Resistance & Reaction
Reaction to fire is the contribution made by a combustible material
to fire growth when it comes into contact with it.
In general, materials are divided into six classes ranging from “fireproof”
to “easily inflammable”. Glass products are of mineral
origin and are considered class 0 products because they are
fireproof.
Panels and walls built with Seves glass blocks offer a good level
of fire resistance. The barrier that they create ensures the level
of fire resistance guaranteed by stringent quality control procedures
adopted by Seves for its products in order to increase
their safety.
The purpose of quality control is to verify the stability of the panel
under the effects of flames over time as well as its ability to
contain heat transmittance and to prevent the passage of gas
and vapours generated by the combustion.
