FireMaster Concertina is a fire curtain that protects WITHOUT the need for CORNER POSTS giving architects, consultants and specifiers a whole new way to approach buildings design. The FireMaster Concertina offers up to 4 hour fire integrity using our revolutionary, tested folding system which can form almost any shape.
The complete assembly of our FireMaster Concertina remains concealed in the ceiling space until it is required to deploy in a fire event. Need reduced irradiance or insulation – see FireMaster Plus Concertina.
The barrier assemblies shall be constructed from pleats. The material keeps the memory of the folds as manufactured. As the bottom tray deploys these pleats unfold. During retraction of the curtain the pleats will neatly fold back to their stored position.
Metalwork is zinc coated mild steel. This can be painted on site or powdercoated to RAL colours.
The active fire curtain barrier assemblies will remain retracted within its headbox until it is automatically activated by the fire alarm signal. Upon activation the active fire curtain barrier assemblies will deploy by gravity to its fire operation position, completely closing the opening and creating a fire compartment.
