Overview
About Firestop pillows and bags
Intumescent pillows are packed tightly into openings around cable trays and expand in fire to close the gaps.
They are tested as penetration seals (EN 1366-3, UL 1479 / ASTM E814, AS 1530.4) for the opening size and services in the system.
Because they are removable, they suit temporary seals during construction and frequent cable changes.
Key benefits
- Removable and reusable
- Fast installation, no curing
- Ideal for changing cable loads
- Temporary or permanent seals
