FJ240 Spanatherm is a strong pre-engineered rock fibre movement-joint fire seal, vertical fibre orientation, that allows significant movement accommodation at the same time as providing fire integrity, insulation and an effective smoke seal. FJ240 is a dense rock mineral fibre board Class A1 core with a BC0 aluminium foil applied to two faces. This provides a vapour barrier and a smoke seal when correctly sealed.
FJ240 is a cost effective and efficient product for compartment reinstatement at edge of slab, or vertically, to external façade of the structure. Suitable for both static or movement joints.
