Firefly Intusil

Up to FRL -/240/240

Used to provide a highly flexible (low modulus) water proof fire seal to gaps and joints up to 25mm requiring up to 50% movement accommodation. Particularly suitable for use on non-porous surfaces, such as metal, glass and many polished surfaces, including curtain walling. Intusil contains no halogens and produces very low smoke emissions during fire attack making it extremely suitable for use in confined spaces, underground or in marine environments. Whereas some polyurethane based waterproof fire rated sealants, may not be suitable for enclosed spaces as polyurethane has been known to emit extremely toxic gases when exposed to fire.  Intusil is also used for sealing up external joints on roofing, barge and eave linings, where buildings are constructed in areas designated as BAL-FZ or lower. Bushfire Attack Level – Flame Zone is the highest level of Bushfire Attack.
