    Nullifire (Intusil)

    Nullifire is a fire rated silicone sealant which may be used to seal movement joints where a fire rating is required.

    Nullifire is an atmospheric moisture curing one part silicon sealant, supplied in 310ml cartridges. The colour is white.

    One of its biggest benefits: It is fire tested to 4 hours integrity to BS 476 pt 20.

    Nullifire is used to provide a highly flexible (low modulus) fire seal to gaps and joints up to 25mm requiring up to 50% movement accommodation.  Joint design should be in line with BS 6213.

    Nullifire contains no halogens and produces very low smoke and minimal toxic fumes during fire attach, making it very suitable for use in confined spaces, underground or in marine environments.

    Particularly suitable for use on non-porous surfaces, such as metal, glass and many polished surfaces, including curtain walling.  It can also be used around pipes and cables.
