Intumescent Pillow

PFC Corofil Intumescent Pillows can be used as a temporary and permanent firestopping system where steel trunking and cable trays penetrate a masonry, concrete or block fire resisting wall. They can also be used in larger apertures in fire resisting rigid walls. The intumescent pillows are located centrally within the wall construction and held in place by their own weight and induced friction.
