Graphite based intumescent sheet encapsulated in a polythene sheath, designed to be wrapped around the outside diameter of pipework or trunking and secured by means of a self-adhesive strip. The Intumescent Pipe Wrap is positioned within the line of compartment wall or floor with the edge of the product left exposed at the face of the wall or floor to be activated by the heat of the fire. The pipe wrap is then sealed into the structure with ROCKWOOL Firepro Firestop Compound.
Under fire conditions, the intumescent material expands against the structure and ‘chokes’ the void left by the melting plastic.
For walls greater than 100mm thickness and where fire resistance is required from both sides it may be necessary to fit 2 wraps. Where pipes are insulated, it is recommended that ROCKWOOL Insulated Fire Sleeves are considered.
