What is Nullifire FI025 Intuflex Insulation Wrap?

Nullifire FI025 Intuflex Insulation Wrap is a fire insulation upgrade material, primarily made from rock mineral fibre, with an outer layer of foil to provide a class O surface spread of flame around a class A1 core. The foil facing in conjunction with aluminium foil finishing tape, leaves an aesthetically pleasing finish with zero fibre migration.

What applications can Intuflex be used for?

FI025 Insulation Wrap is designed to upgrade the insulation rating of uninsulated penetrated services (where required) which have been sealed using a Nullifire product. The application of FI025 around most services increases the “I” rating to that required by the compartment line. FI025 has been tested around copper and steel pipes up to 160 mm diameter, cable trays, ladders and baskets, individual cables and cable bundles up to 100 mm diameter.

Always read SDS, pre-application guidance and relevant application detail prior to application. Ensure the latest documents are downloaded prior to every project commencement.

FI025 increases the insulation performance of the penetrating service, and not of the primary seal. Please ensure that the primary seal fire performance meets the capability requirements of the compartment or the strategy.

Safety data sheet must be read and understood before use.
