Seal Systems

AstroFlame – Pillows

Manufactured from a hard wearing specially treated glass cloth filled with a mixture of mineral fibre and reactive expansion agents, which on exposure to heat from a fire will first expand and then harden to provide a complete and durable seal against the passage of fire, smoke and hot gases.

Intumescent Fire Pillows can be used for creating either temporary or permanent fire barriers and are ideal for sealing cable trays and ducts that penetrate fire rated structures.
