Application

Suitable for providing a seal between the top of the compartment wall, partition, or fire-resistant suspended ceiling, and the structural soffit.

Description

The SIDERISE TW Firestops for Tops of Walls comprises a single, close dimensioned product with a pre-compressed internal stone wool mineral fibre lamella core.

The firestops provide 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 the 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.
  • Can accommodate structural service movement (during normal service life and fire).
  • Contains no Volatile Organic Compounds (VOCs) and no Very Volatile Organic Compounds (vVOCs).
  • Zero ozone-depleting potential (ODP).
  • Zero global warming potential (GWP).
