Siderise RF Systems prevent the spread of fire and smoke, and reduce sound transmission, by sealing the voids between raised access floors and floor slabs.
The range includes options to either subdivide large uninterrupted cavities (Cavity Barriers) or to provide continuity of fire resistance when aligned underneath partitions (Fire Stops). Across the range, these simple to install systems have been tested for fire performance, acoustic performance and for use as a plenum liner.
Siderise RF-CB cavity barrier systems are used to subdivide uninterrupted voids in accordance with Building Regulations and offer 30 minutes fire resistance (EI 30). CB barriers are designed to suit individual floor void depths between 50mm and 600mm (see Table 1 for ratings by void size)
Siderise RF-FS fire stop systems maintain continuity of fire resistance for installations aligned with fire rated partitions hence maintaining compartmentation. The 'FS' systems offer 60 to 120 minutes fire resistance.
RF-FS barriers are designed to suit individual floor void depths between 50mm and 600mm. They have been designed as a one-piece system and afford easy cutting and installation. Additionally, due to a unique manufacturing process, the products also offer unique vertical compression to allow tightness of fit.
Siderise RF Systems have Certifire 3rd party approval (CF 5646) please refer to Table 1 for details.
Siderise RF cavity barrier and fire stop systems are classified A1 to EN 13501-1 and comprise a unique non-combustible stone wool lamella core, which is faced on two sides with an impervious aluminium foil, offering excellent resistance to the passage of smoke.
Siderise RF is available in the following forms:
• Pre-cut products are available in 1mm increments of width to suit the cavity size. Please see Table 1 regarding 'fit type'.
• Supplied with appropriate brackets as part of a system.
• Standard sheet size is 1200 x 1200mm and may be of benefit when the actual void size is not known or where it varies significantly.
• Appropriate brackets must be ordered separately.
Siderise RF cavity barrier and fire stop systems have been successfully tested to the latest European standards - EN 1366-4 for up to 120 minutes fire resistance (integrity and insulation).

The installation of Siderise RF cavity barrier and fire stop systems substantially enhances the ‘room-to room’ sound reduction of raised access floors which form a continuous common void under adjacent areas. This invariably results in improved speech privacy and greater control of disturbance from intrusive noise.
The excellent acoustic performance of the RF material is due to the unique internal construction of the stone wool lamella core. Also, the rebated overlap joints, foil facings and the additional sealing of the vertical joints with foil tape all serve to provide improved air tightness.
Based on laboratory tests to determine airborne sound transmission in accordance with BS EN ISO 140-3 : 1995, BS 2750 : Part 3 : 1995 on a variety of Siderise RF systems the following Weighted Sound Reduction Index (Rw) values can be used: as shown in table 3 below. Sound Research Laboratories Limited test report no. : C/99/5L/7743/I refers.
Actual performance will be dependent on several factors including the design, choice of materials and degree of fit between components.
For raised access floor systems requiring higher ‘cross-talk’ values i.e. approx. 45+dB, the improvement in ‘cross-talk’ value may be limited by other factors, including flanking transmission, leakage through M&E systems etc.
However, for installations offering a reduced ‘cross-talk’ performance, such as installations with frequent service openings, larger improvements can be affected by the installation of the RF before reaching limiting values. In such instances, improvements up to 20dB may be possible.
