Raised Access Floor Barrier
For voids beneath raised access floors
PRODUCT
AIM Raised Access Floor Barrier prevents the passage of flame and smoke through the under floor cavity, for at least the period of fire rating specified. AIM Raised Access Floor Barrier is made from high density Rockwool stone wool slab, faced with Class 0 impervious foil facing on both sides. It is available cut to size or in slabs suitable for cutting on site.
APPLICATIONS
Raised Access Floor Barriers are required for four
applications (requirements for fire barriers):
1 - Subdivision of large uninterrupted cavities
To comply with Building Regulations - 30 minutes’
integrity plus 15 minutes insulation. The AIM Raised
Access Floor Fire Barrier meets and exceeds the
requirements of Approved Document Part B (in
England and Wales) as well as the fire safety sections
of other UK Building Regulations’.
2 - Alignment under a partition, to maintain partition rating
i) 30 minute partition - 30 minutes’ integrity plus 30 minutes’ insulation
ii) 60 minute partition - 60 minutes’ integrity plus 60 minutes’ insulation.
iii)120 minute partition - 120 minutes’ integrity plus 120 minutes’ insulation
3 - Reduce flanking transmission of sound
The AIM Raised Access Floor Barrier can be used to reduce flanking transmission of sound through the void it fills by at least 21 dB RW
4 - Plenum Applications
The AIM Raised Access Floor Barrier can also be used to help create a Plenum chamber under a raised access floor system.

TECHNICAL INFORMATION
FIRE PERFORMANCE
Tested to BS EN 1366-4:2006+A1:2010.
Achieves the Euroclass rating of A1, non combustible.
The access floor and structural slab should have a proven fire rating at least equal to that of the barrier.
| Fire Rating | Integrity | Insulation fire resistance | Barrier thickness | Maximum void |
|---|---|---|---|---|
| 1/2 hour | 120 minutes | 30 minutes | 75mm | 400mm |
| 1 hour | 120 minutes | 60 minutes | 100mm | 400mm |
| 2 hour | 120 minutes | 120 minutes | 125mm | 400mm |
ACOUSTIC PERFORMANCE
AIM Raised Access Floor Barrier provides at least 21dB Rw sound reduction. The acoustic performance of the floor system must also be considered when assessing the room-to-room sound reduction figure.
Plenum Chambers
AIM Raised Access Floor Barrier may be used to create a plenum chamber however the effectiveness of the barrier is dependent on the quality of the installation. (or similar).
AS STANDARD
AIM Raised Access Floor Barrier is supplied pre-cut
in 1000mm lengths and three standard thicknesses
depending on the fire rating required. The product
supplied is as required to fill the void.
The pre-cut product is supplied with the required
fixing clips.
OPTIONS
The AIM Raised Access Floor Barrier is also available
in slab form for cutting on site as required. When
ordering in slab form the clips should be purchased
separately.
The product is also available fully foil enclosed for use
within plenum applications. It can also be suppled
polythene sleeved.
Foil tapes of 45m length and in widths of 100, 125
and 150mm for the optional sealing of joints.
TEST REPORTS
Test reports WF 432725 & WF 432729 cover the use
of AIM Raised Access Floor Fire Barrier in cavities up
to 400mm.
Tests are conducted to BS EN 1366-4:2006+A1:2010
and the principles of TR31.
INSTALLATION GUIDELINES
AIM Raised Access Floor Barrier is friction fitted into place in conjunction with fixing clips; it must fit tightly and completely fill the void with 5% compression.
