It comprises a single, close dimensioned product with a unique pre-compressed internal stone wool mineral fibre lamella core.

It provides a seal between the top of the compartment wall, partition, or fire resistant suspended ceiling, and the structural soffit. The choice of material is determined by the performance requirement in terms of fire resistance (i.e. insulation and integrity) and size of cavity.

Features and benefits:

  • Ease of installation.
  • Fire-stops for tops of walls provide excellent acoustics performance and can help to reduce room-to-room sound transmission. Their high performance is attributable to the mass of the mineral fibre core and the unique resilient lamella internal construction.
  • The products have integral aluminium foil facings and are a functional smoke barrier.
  • Vertical joints between adjacent strips are sealed with foil tape to maintain continuity of the smoke barrier foil facings and to enhance the fire and acoustic integrity of the assembly.
  • It can accommodate structural service movement (during normal service life and fire).
  • It contains no Volatile Organic Compounds (VOCs) and no Very Volatile Organic Compounds (vVOCs).
  • Zero ozone depleting potential.
  • Zero global warming potential.
  • Recyclable.
  • Cost effective.
  • Durable.

Standard product features

  • Form supplied: Sheets 1200 x 1200 mm x thickness. Cut strips 1200 mm x cavity + compression x thickness.
  • Colour: Silver, with coloured identification tape centrally located on product.
  • Finish: Aluminium foil.
  • Density: Nominal 80 Kg/m³.
  • Thermal conductivity: l20 = 0.04 w/mK.
  • Cavities: 20–400 mm. See Certifire CF563.
  • Fire resistance: 30–120 minutes EI (insulation/ integrity).
  • Reaction to fire: Class ‘A1’, Class ‘O’.

Options

Fixing brackets:

Fixing brackets are not required for voids below 50 mm. For voids above 50 mm fixing brackets are incorporated into the assembly to maintain the integrity of the construction. They are simply impaled into the base of the barrier at mid-thickness prior to installation. Two brackets are required per unit.

The standard fixing brackets are supplied in flat pre-notched form for folding on site to the requisite “L” or “Z” shape. They are pre-cut to a spike so that the long leg can penetrate into the barrier.

Fire performance:

  • The design and manufacture of the range of Siderise fire-stops for tops of walls is based on proven fire performance to BS 476-20: 1987.
  • The products are formally Third-Party Approved by Warrington Certification Ltd (part of Exova Group) under their ‘Certifire’ scheme - see ‘Certifire’ approval certificate No. CF563.

In terms of ‘Reaction to Fire’, the products provide the following:

  • Class ‘A1’, in accordance with EN13501-1 and EC Decision 96/603/EC .
  • Class ‘0‘, in accordance with BS 476 Part 6 & 7.
