A dry-fit slab edge fire stop, Paraflam Ultra is an A1-rated, non-combustible, flexible system that has been designed to address fire risks associated with curtain wall facades, namely preventing the spread of fire around the slab edge for a set period of time. This supports compartmentation systems in containing the spread of fire from one floor to another.
Paraflam Ultra provides up to two hours of fire protection for horizontal slab edges in curtain walling systems and is tested to the European standard for curtain walling systems EN1364-4.
Importantly, testing has also included the need for movement accommodation, with Paraflam Ultra providing up to 6% of compression and expansion that’s essential to maintain the seal between the rigid materials of the slab and facade in tall buildings when they’re subjected to movement.
As a dry-fit design, the system is compression fitted to ensure compartmentation is reinstated at the slab edge to prevent the spread of fire, allowing occupants time to escape the building in the event of a fire, and fire fighters time to respond.
