The Quelfire QuelStop Intumescent Fire Pillow is a flexible, removable firestop solution designed for use inside steel cable trunking systems that pass through fire compartment walls. Filled with organic materials and intumescent additives, these pillows expand under heat to seal voids, preventing fire and smoke from spreading.
Ideal for retrofit and temporary firestopping, they can be easily installed or removed without compromising performance. Each pillow is wrapped in a moisture-resistant glass cloth case, offering durability and temperature resistance from -20°C to +130°C.
Tested in accordance with BS EN 1366-3:2009, these CE-compliant fire pillows deliver up to 60 minutes of fire integrity, providing a fast, compliant solution for cable containment routes.
