Any seismic /curtain wall panel gap 10mm to 30mm can be filled with an intumescent packed foam strip and at times will get coated with a fire rated sealant. Gaps 30mm to 130mm can be filled with a flexible foam/intumescent block strip fixed either under pressure or mechanically with Z brackets to one side if required.
Any other gaps 130mm to 1.1m can be treated with the installation of a fire rated canvas/fibre blanket. The blanket can be installed to provide up to 400mm movement in any direction (the bigger the gap width the less available movement). It can achieve up to a 60min rating.
