ZeroPlus increases scope of fire-rated product

ZEROplus’s FBLS Fire Block Louvre System is now suitable for use in previously successfully tested steel fire doors to BS EN 1634-1:2014.

The FBLS still offers up to 240 minutes integrity protection. The firm has increased the size scope it can offer to a maximum square cut-out of 660mm wide x 660mm
high, and a maximum rectangular cut-out of 483mm wide x 1676mm high. The FBLS is now suitable for 240-minute steel integrity only fire doors to BS EN 1634-1:2014. 

Although this new testing and size scope only relates to fire-rated steel doorsets, the FBLS is still assessed for use in previously successfully fire tested timber doorsets for both 30 and 60-minute durations, again to BS 476: Part 22: 1987, to a maximum aperture size of 610mm x 610mm.
