Fabric is traditionally considered as combustible materials and is unable to provide any fire resistance capacity. Breakthrough has been made in fire resistance of fabric for fire protection. New technologies turn stainless steel into yarns and in turn making fire resisting fabric which can stand for more than 4 hours fire resisting rating. The new fire resisting fabric provide light weight and slim design characteristics, which are favorably applied in passive fire protection for fire shutters, smoke curtains, fire barriers, and temporary fire rated partition..etc. With the support of fire resisting stainless steel thread, the new fire resisting fabric can be sewed to large size up 10 m by 18 m or larger. With the application fire resisting coating and combining the fabric with other composite materials, it can further provide with extra fire resisting capacity with long duration integrity and insulation which cannot be provided by convectional metal fire shutter. The new fabric has been tested to BS476 Part 20, 21 and 22 as well as EN 1363-1, 1364-1, and 1634-1 for 30 minutes, 60 minutes, 120 minutes and 240 minutes integrity and insulation.
The new application of fabric in fire resisting construction can fully compliance with the fire resisting requirements in the new Code of Practice for Fire Safety in Building 2012. Its light weight and slim characteristics can significantly reduce space and loading requirements and provide highly cost effectiveness in passive fire protection. Nowadays, there are imminent needs for the building industry, building authority , fire authority, architects and fire engineers in Hong Kong to update their advanced technology in passive fire protection.
In this talk, Ir Leung will cover the following areas of advanced technology of fabric for passive fire protection.
1. The new development of technologies in fire resisting fabric which is considered to be suitable and applicable to Hong Kong construction industry.
2. The current problems and advantages with application of advanced technologies in fire resisting fabric for passive fire protection
3. Cost effectiveness of applying advanced technology of fire resisting fabric in passive fire protection.
