Firestop & Penetration Seals

Firestop & Penetration Seals

What are Firestop & Penetration Seals?

In every building or industrial facility, service penetrations such as cables, conduits, and pipes create weak points in fire-rated walls and floors.
During a fire, these penetrations can allow smoke, flames, and toxic gases to spread rapidly, compromising safety and evacuation.
Firestop & Penetration Seals are engineered solutions that restore the fire-resistance rating of walls and floors by sealing gaps around services, ensuring fire and smoke cannot pass through.
