AIM Fire Stop Strip is made from high density rock 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. The barrier must be compressed by about 5% when installed. AIM Fire Stop Strip is generally incorporated into the building during construction and is used to seal gaps between different building elements such as the top of a wall and the underside of a floor. The building elements must also have the fire rating required for the fire stop strip. For gaps greater than 100mm above masonry walls and partitions, use AIM Partition Head Barrier.

Installation

AIM 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 joins also must be tight. A small piece of metal or plastic sheet may be temporarily inserted as a slip plate, if rough masonry surfaces cause problems. If the gap to be filled is between two components which might separate in a fire, the two components must be connected with steel brackets to ensure that the distance of separation cannot increase.

Typical Applications

EXPANSION JOINT IN MASONRY WALL TOP OF WALL TO HOLORIB SOFFIT

TOP OF WALL TO METAL DECK (RUNNING PARALLEL) TOP OF WALL TO METAL DECK (CROSSING WALL)

The performance of AIM Fire Stop Strip has been tested to BS 476 part 20 and assessed by Warrington Fire Research Centre to achieve the values stated below.

AIM Fire Stop Strip is incombustible to BS 476 part 4, rated Class 1 Surface Spread of Flame to BS 476 part 7 and complies with the performance requirements of Class O of the Building Regulations

Thickness of Fire Stop

Thickness is measured as the distance between one compartment and the next, which the fire stop or barrier is separating.

Composition & Durability

AIM rock wool products 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 normal conditions found in buildings, and will perform effectively for the life of the building.

Handling & Storage

AIM rock wool products are easy to handle, but should be treated with relative care to ensure their integrity and shape is maintained. They should be stored in fairly dry conditions. Should indoor storage be impossible the product should be stacked clear of the ground and covered with a stout tarpaulin.

Acoustic Rating

AIM Fire Stop Strip will reduce flanking transmission of sound through the void it fills by at least 9dB. When installed in a 50mm gap above a partition and where an imperforate 12.5mm plaster-board 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.

Save Money and DO IT RIGHT the First Time!


Balanced Approach toFire Barrier Management Education

Contractor/Pre-Construction Meetings

At a pre-construction meeting with sub-contractors we explain compliance requirements from paperwork to

installed firestop verification, setting the standard for the jobsite.


In Summary …

Proper firestopping protects critical assets

Firestopping is not going away

It is in the code(s)

Inspectors, buyers and owners are getting educated

Firestop can be a value add, billable activity for your company if managed properly

It is cheaper to do right the first time

Industry resources in assessment, project management inspection and training are available

Liability Management


A small leak will sink a great ship.

To err is human, to repent divine; to persist devilish.

An ounce of prevention is worth a pound of cure.

Little strokes, fell great oaks.

After crosses and losses, men grow humbler and wiser.
