Sika-Firestop is a slightly alkaline, inorganic silicate-based sealant. It is capable of withstanding temperatures up to 1000 C. At temperatures in excess of 250 C carbon dioxide (CO2) is produced, causing the material to undergo expansion. Because of its inorganic composition Sika-Firestop is ideally suited for the sealing of joints in areas where fire safty is a requirement. Typical applications include seals to: Fire check doors, fireplaces, chimneys, cable entries etc.
