Firefly Large Movement Seismic Joints
The Firefly Seismic/movement control systems are generally used to provide very large fire rated linear gap seals of up to 1.2m wide x infinite length which need to accommodate a lot of movement. Both edges of the Firefly material need to be mechanically fixed/clamped to either the face/top or bottom of the concrete slab or block wall. Simply sag the amount of material into the gap to allow for the amount of movement required. Various FRL’S are achieved from -/90/- up to -/120/120 dependant upon which product you use.
