Siderise RF Cavity Barrier and Firestop Systems prevent the spread of fire, 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. See Table 2 of the manufacturer's technical datasheet for ratings by void size.

Siderise RF-FS Firestop 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. They are a one-piece system that affords easy cutting and installation. Additionally, due to a unique manufacturing process, the products offer unique vertical compression to allow tightness of fit.

Siderise RF Cavity Barrier and Firestop Systems have been tested in general accordance with EN1366-4. Please refer to Table 2 of manufacturer's technical datasheet for details.

RF Cavity Barrier and Firestop systems are classified A1 to EN 13501-1 and comprise a unique non-combustible stone wool lamella core with vertically orientated fibres laterally compressed and held in place by aluminium foil facings on two sides.

Siderise RF is available in the following forms:

Pre-cut Strips

• Pre-cut products are available in 1 mm increments of width to suit the cavity size. Please see Table 2 of manufacturer's technical datasheet regarding 'fit type'.
• Supplied with appropriate brackets as part of a system.

Sheets

• Standard sheet size is 1200 x 1200 mm and may be of benefit when the actual void size is not known or where it varies significantly.
• Appropriate brackets must be ordered separately.

Features and benefits:

• Two hours' fire resistance: RF Cavity Barrier and Firestop systems have been tested to EN 1366-4 for up to 120 minutes' fire resistance (integrity and insulation).
• Tested acoustic performance: RF Cavity Barrier and Firestop systems can reduce room-to-room sound transmission, improving privacy and preventing disturbance from neighbouring rooms.
• Range of applications: RF Cavity Barrier for use in void heights up to 400 mm. RF Firestop is suitable for use in void heights up to 1000 mm. Both suitable in air plenum applications.
