FSI S-Line Intumescent Pillows – box

FSI S-Line Intumescent Pillows can be used to create either a temporary or permanent fire seal around service penetrations.

They are particularly useful in services which require regular maintenance and access, as they can be removed temporarily.

These fire pillows can be used around services which pass through a compartment wall or floor.

Comes in three different sizes: 330x50x20mm, 330x200x50mm, 330x200x45mm.

How do intumescent pillows work?

The intumescent material in the pillows expands when exposed to extreme temperatures, such as in a fire.

When the fire pillows are positioned together, they lock together to form a collective seal.
