FIREFLY Silicone is an atmospheric curing, one part silicone sealant formulated to provide a high degree of fire resistance in a variety of joint configurations.

Used to provide a highly flexible, low modulus, waterproof fire seal to gaps and joints up to 25mm wide, capable of accommodating up to 25 % movement. Particularly suitable for use on non-porous surfaces such as metal, glass and polished surfaces including curtain walling. FIREFLY Silicone contains no halogens and produces low smoke emissions during fire attack, making it suitable for use in confined spaces, underground or in marine environments. Used for sealing external joints on roofing, barge and eave linings where buildings are constructed in designated BAL 40 to BAL-FZ bushfire attack level zones.
