Yes! We realise it sounds odd, but active fire curtains are a form of passive fire protection – they don’t suppress the fire, they merely compartment and stop spread like walls, fire rated glazing, fire doors etc. The word ‘active’ describes them in contrast to static fire curtains. Active fire curtains are ‘invisible’ (out of sight) until needed and then deploy on fire alarm, to provide the passive fire barrier required. Static fire curtains are permanently in place e.g. in loft spaces where no access is required.
