The Metacaulk Wrap Strip is a flexible, pre-cured dry intumescent strip designed for firestopping plastic and insulated pipe penetrations.

When exposed to heat, it expands to form a protective char that helps seal openings and prevent the spread of flames, smoke, and toxic fumes.

Simply wrap the required number of strips around the penetrant to fill the annular space and create a reliable firestop seal. Designed for easy installation with no curing time required, Metacaulk Wrap Strip is an efficient and cost-effective solution for through-penetration firestop applications.
