Fire Stop Strip
Fire and smoke stop for linear gaps or imperfections of fit in buildings.
PRODUCT
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
APPLICATIONS
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:
- Top of masonry wall under soffit
- Above partitions
- Movement joint in masonry wall
- Within metal cladding systems
- Between ceilings and walls
- Metal Decking, Roofing and Cladding
FEATURES
- High Density Rock stonewool strips typically supplied 1200mm long
- Up to 400mm wide and suitable for voids of up to 100mm.
- Suitable for horizontal and vertical applications
BENEFITS
- 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.
- No mastics or sealants required

PHYSICAL INFORMATION
• Lengths: 1200mm
• Widths: up to 400mm
• Voids: 10 - 100mm
PACKAGING
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.
AS STANDARD
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).
ANCILLARIES
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
A COMBINED SOLUTION FOR FLAT ROOFING
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 PERFORMANCE
Fire Rating Cavity width 100mm
Fire rating (integrity / insulation) - all horizontal and vertical use
| Application | 75mm | 100mm | |
|---|---|---|---|
| Masonry to Masonry | Yes | 120/60 | 120/120 |
| Masonry to Softwood | Yes | 30/30 | 60/30 |
| Masonry to OSB | Yes | 30/30 | 60/30 |
| Masonry to CP Board / SFS | Yes | 30/30 | 60/30 |
Fire Stop Strip is designed for closing small voids up to 100mm.
It is installed under compression (minimum 5% compression required).
It should be installed with fixing clips (except at the head of a masonry wall).
ACOUSTIC PERFORMANCE
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

INSTALLATION GUIDELINES
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.
ITEMS REQUIRED FOR INSTALLATION
• PPE abrasion resistant gloves
• PPE impact resistant goggles
• RPE dust mask
STORAGE
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.
MAINTENANCE
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.
DURABILITY
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.
HEALTH & SAFETY
Insulation products supplied by AIM are considered
to be inert articles and as such are exempt from
requirements to provide a Safety Data Sheet.
A Product Safety and Handling Information Sheet is
available upon request.
