What is a major advantage of firestop putties?

Firestop putties are specifically designed to seal voids and openings in fire-resistance-rated assemblies, and one of their major advantages is that they maintain a soft consistency until heated. This property allows for easy application and repositioning during installation, enabling technicians to effectively fill gaps around cables, pipes, and other penetrations that require firestopping materials.

When exposed to heat or fire, these putties will then harden and form a durable barrier that helps to prevent the spread of flames and smoke between compartments in a building. This transition from a pliable state to a hardened state enhances their functionality during fire events.

The ability to remain soft until heated makes firestop putties user-friendly and efficient in installation processes, allowing for adjustments to be made before they cure. This flexibility is crucial in achieving a proper fire stop installation, which is vital for maintaining building safety and code compliance.
