 FSi Promat Facade Fire Protection

  Paraflam® Seb    Paraflam® SEB is a closed state cavity barrier that’s installed at the vertical compartment lines in rainscreen applications and for use in masonry applications. With no requirement for an air gap in the vertical barriers, Paraflam SEB is friction fitted using brackets, providing an effective smoke & flame seal.

 

 

 

  Silverliner® Open State Cavity Barrier (OSCB)    The Silverliner® Open State Cavity Barrier (OSCB) has been developed for use in a ventilated façade, allowing for a 25mm or 50mm air gap to ensure that air can move through the facade and any moisture can drain away. The aluminium foil coating stops the migration of fibres and offers a Class 0 rating.

If a fire occurs, the outer edge of the cavity barrier will expand and close the ventilation gap, stopping flames and smoke from travelling to other parts of the building.

 

 

 

  Paraflam® Ultra    Paraflam® Ultra is a perimeter fire stop designed for curtain walling and perimeter facades. Paraflam Ultra is a non-combustible stone wool-based product with a foil facing which prevents fibre migration and provides an excellent seal. It is designed to reinstate the fire resistance of a compartment.
