Fire-resistance expanding foam

Fire resistance

— mounting foam with increased resistance to fire, used, in particular, to protect joints from flames and smoke. Full-fledged fire-fighting foam does not ignite even under the influence of an open flame and is able to delay the ignition of the elements under it for up to several hours. At the same time, we note that sometimes the so-called fire fighting is called. self-extinguishing foam with a lower fire resistance class: such a composition does not burn on its own, but burns out under the influence of a flame. So before buying foam, positioned as fireproof, it's ok to clarify its specific properties.
