Door Industry Journal - Winter 2021

THE door industry journal winter Also online at: www.dijonline.co.uk Fire Doors, Safety & Security Committed to being at the forefront of testing, ZEROplus are excited to announce that following a successful program of fire testing, their popular FBLS Fire Block Louvre System is now suitable for use in previously successfully tested steel fire doors to BS EN 1634-1:2014. Although BS EN 1634-1:2014 is a more onerous standard, no compromise was made regarding the duration they wanted to achieve, meaning the FBLS still offers up to 240 minutes integrity protection. Furthermore, they have increased the size scope they 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. • Now suitable for 240-minute steel integrity only fire doors to BS EN 1634-1:2014 • Complete system – not just an intumescent block • Heavy-duty steel louvres • Over 25 sizes from stock, available immediately • Large ‘full door’ sizes tested and covered • Non-vision for privacy • Suits doors of 44mm minimum thickness – no maximum thickness Mark Lockley, Sales Director at Zero explained: “Having certification to BS EN 1634-1:2014, full door sizes (providing they are mounted above 500mm from the floor), and a duration of 240 minutes, makes the FBLS the market- leading intumescent louvre system for steel fire doors”. 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.
