AIM Fire Stop Strip is a high density Rockwool stone wool fire and smoke stop for medium size linear gaps in buildings. AIM Fire Stop Strip is permanently held in place by compression without the need for adhesive or intumescent mastic. It prevents the passage of flame and smoke through the void being fire stopped.SPECIFICATIONLengths: 1200mmVoids: 10-100mm (For voids 100mm to 600mm use AIM Partition Head Barrier)Up to 4 hours fire ratingNo mastics or sealants requiredTested to BS476 part 20 and assessed by Warrington Fire Research CentreOzone depletion potential of zero, no CFCs or HCFCs used in manufactureGlobal warming potential= zeroAPPLICATIONTop of masonry wall under soffitAbove partitionsExpansion joint in masonry wallWithin metal cladding systemsBetween ceilings and wallsThe performance of AIM Fire Stop Strip has been tested to BS 476 part 20 and assessed by Warrington Fire Research Centre.Fire ResistanceMinimum Thickness of Fire Stop mmMinutesGaps up to 75mmGaps up to 100mm30505060607512075100240100 EHD*100 EHD**EHD - Extra High Density barrier with lap jointsACOUSTICSWhen installed in a 50mm gap above a partition and where an imperforate 12.5mm plasterboard ceiling is installed to abut the partition below on both sides, the room-to-room sound reduction, on the path of the Fire Stop Strip, will be at least 47dB average sound reduction index.INSTALLATIONAIM Fire Stop Strip must be compressed by about 5%, when installed. It is push fitted into place and must fit tightly and completely; all butt joints also must be tight. Where rough masonry surfaces cause problems a small piece of metal or plastic sheet may be temporarily inserted as a slip plate. If the gap to be filled is between two components which might separate in a fire, the two components must be mechanically linked so that separation cannot occur.
