AIM Fire Stop Strip is made from high density
Rockwool stonewool 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 100mm 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 Strips have been tested for use with a variety of wall constructions including timber framed, SFS with CP board facing as well as conventional masonry.
Typical applications include:
• Lengths: 1200mm
• Widths: up to 400mm
• Voids: 10 - 100mm
• (For voids 100mm to 600mm use AIM Partition Head Barrier
AIM Fire Stop Strips are generally packed into cartons and stretch wrapped onto wooden pallets with a showerproof polythene pallet cover and high quality edge protectors.
AIM Fire Stop Strip is manufactured in lengths of 1200mm with depths and widths to suit the void size (with an additional 5% depth to allow for the compression fit).
AIM Fire Stop Strips are often used in conjunction with AIM Fire Stop blocks. The Fire Stop Strip will accept deflection from the floor above and can be used to seal imperfections in the wall construction
Where a fire wall is built to the underside of a perforated metal deck, AIM Fire Stop Blocks should be installed above and below deck at the line of the wall to ensure that smoke or fire is prevented from passing through the perforations in the metal work.
AIM Fire Stop Strip can also be used to remove any
imperfections in the head of the wall to the underside
of the metal deck.
AIM Acoustic Trough Infills are then used across the metal deck, to assist with the reduction of noise reverberation from within the building.
The performance of the AIM Fire Stop Block is dependent on the metal deck remaining stable in a fire situation and should be assessed by a competent person.

Fire Stop Strip is designed for closing small voids up
Not tested in cavities over 100mm. Please use the AIM Partition Head Barrier in these situations. It has been tested vertically and horizontally to BS EN 1366-4.
It is installed under compression (minimum 5% compression required).
It should be installed with fixing clips (except at the head of a masonry wall).
AIM Fire Stop Strip provides at least 14dB RW sound
reduction. The acoustic performance of the floor
and wall systems must also be considered when
assessing the room-to-room sound reduction figure.
75mm long block = 14dB RW
100mm long block = 18dB RW
140mm long block = 23dB RW
Z11012 – Acoustic Performance – Testing on mineral fibre insulation. To BS EN ISO 10140-2.
More drawings available in the Technical Guide which can be downloaded above.
AIM Fire Stop Strip must be compressed by minimum of 5% compression, when installed. It is push fitted into place and must fit tightly and completely; all butt joints also must also be tight. Where rough masonry surfaces cause problems a small piece of metal or plastic sheet may be temporarily inserted as a slip plate. The plate should be removed once installation has been completed.

• PPE impact resistant goggles
• RPE dust mask
Products are supplied in cartons and on wooden pallets with edge protection and a shower proof hood. Products should be stored away from the elements until ready for installation.
This product does not contain moving parts and,
if undisturbed in the cavity, requires no routine
inspections or maintenance.
It is recommended that the integrity of the barrier is rechecked if further works are carried out, which may involve disturbing the product.
AIM fire barriers are chemically inert, will not sustain vermin and do not encourage the growth of rot, fungi, moulds or bacteria. They are compatible with all normal building materials. They do not degrade under the usual conditions found in buildings and will perform effectively for the life of the building.
