Description

AIM Fire Stop Strip is made from high density Rockwool stone wool and 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. For gaps greater than 100 mm above masonry walls and partitions use AIM Partition Head Barrier.


AIM Fire Stop Strips have been developed to prevent the passage of fire and smoke in narrow voids in constructions such as the junctions of compartment walls and floors. The Fire Stop Strip will accept deflection from the floor above and can be used to seal imperfections in the wall construction.


AIM Fire Stop Strip is manufactured in lengths of 1200 mm with depths and widths to suit the void size (with an additional 5% depth to allow for the compression fit).


Features and benefits:

  • High density stone wool strips, typically supplied 1200 mm long.
  • Up to 400 mm wide and suitable for voids of up to 100 mm.
  • Tested to EN 1366-4.
  • Global warming potential = zero.
  • Prevents the passage of fire and smoke through the void.
  • Will help prevent the passage of sound through the void.
  • Can be used as a movement joint in masonry walls when used vertically.
  • Simple to install – no tools required.
  • Up to 2 hours’ fire rating.
  • No mastics or sealants required.
