Fire Rated Sealants

Požarni sektor se smatra vitalnim delom svakog projektnog pristupa za zaštitu od požara i predstavlja oblik pasivne zaštite od požara, jer obično ne reaguje ili se ne menja u bilo kojim uslovima požara. Požarni sektor je u suštini podelilo zgradu u različite “ćelije” kako bi se ograničilo ili zadržalo širenje vatre, toplote i dima u ili iz drugog dela iste zgrade ili susedne zgrade u određeno vreme. Time se štite stanovnici zgrada i dozvoljava im vreme za evakuaciju, a istovremeno pruža mogućnost lokalnim vatrogasnim službama da deluju i smanje potencijalne štete u slučaju požara. Požarni sektori su odvojeni jedni od drugih zidovima u punoj visini i podovima od vatrootpornih materijala i konstrukcije.
