FBLS Fire Block Louvre System
The FBLS Fire Block Louvre System (complete set) consists of an FB intumescent block grille only 14mm thick which fits within the door leaf in the door aperture, and an FDLS two-part steel louvre set which fixes to both sides of the door and sandwiches the FB intumescent block. In the event of fire the intumescent expands 80 times its own volume to fill the door void preventing the spread of flames.
The FBLS Fire Block Louvre System is suitable for previously tested timber fire doors up to 60 minutes and previously tested steel fire doors up to 240 minutes integrity. Fourteen standard sizes are available from stock including 610x610mm and 457x1524mm (width x height). Any size is available to order from 152x152mm minimum cut out. Louvre frames are supplied as standard in galvanised mild steel, already grey primed ready for powder coating. Powder coated finishes and stainless steel frames are available to special order. FBLS suits doors of 44mm minimum thickness; there is no maximum door thickness. Fire rated fusible link louvres and standard non-fire rated louvres are also available from stock.
APPLICATIONS
Fire Block Louvre System is designed to be used on fire rated doors to rooms that require ventilation. A standard louvre will allow ventilation but will also allow the passage of flames and smoke, but FBLS will maintain the integrity of fire doors and prevent the spread of flames. Examples of applications are doors to plant rooms, stores, computer rooms, changing facilities and manufacturing areas. In fact, any area that requires ventilation but is protected by a fire rated door.
