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 impervious foil facing on both sides. It is available cut to size or in slabs suitable for cutting on site. When used in conjunction with Rockwool Ablative Coated Batts underfloor services can be easily accommodated.
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 and typically provides 51 dB when installed with a Tate Global Floor System
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.
5 - Service Penetrations
When used in conjunction with Rockwool Ablative Coated Batts, services such as cable trays and pipes can be accommodated. The system allows for the barrier to be fitted around existing services or they can be retrospectively added.

TECHNICAL INFORMATION
FIRE PERFORMANCE
Tested to BS EN 1366-4
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.
When tested in-conjunction with a carpeted Kingspan Raised Access Floor system, the room to room sound reduction was at least 52 dBnfw through the path of the fire barrier. This result was achieved with all fire solutions.
Plenum Chambers
The ultimate performance of the installations airtightness is highly dependent upon the manner of installation. It cannot be guaranteed prior to site installation and accordingly should be tested at site.
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, clearly identifying small (for voids up to 160mm) or large clips (for voids 161 to 400mm).
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.
Rockwool Ablative Coated Batts and Rockwool Intumescent Mastic for applications with service penetrations.

PENETRATIONS
The system allows for up to five CAT5e or five 2.5mm three core PVC cable to be secured to the substrate and run below the Raised Access Floor Fire Barrier. Please contact AIM for specific installation guidance.
When a penetration service is required to pass through the AIM RAF fire barrier, two 50mm Rockwool FirePro® Coated Batts, having the same height as the AIM RAF fire barrier, are placed on either side of the AIM RAF fire barrier and any small gaps around the penetrating component are filled with Rockwool FirePro® Acoustic Sealant. The horizontal distance from any part of the periphery of the penetrating
service to the nearest edge of the Rockwool FirePro® Coated Batt should be at least 200mm.
Rockwool has a comprehensive range of test evidence for penetrations of cables and pipes, both with a double layer of Rockwool Ablative Coated Batt or with a double layer of Rockwool FirePro® Ablative Coated Batt. The cables tests are based on the Standard configuration for cable penetration systems, Figure A.1 in BS EN 1366-3: 2009 and the plastic pipes are based on Option 1 and the metal pipes on Option 2 in Figure E.1 in BS EN 1366-3: 2009.
