Siderise TW - Firestops for Tops of Walls

Siderise firestops for tops of walls provide a seal between the top of the compartment wall, partition, or fire resistant suspended ceiling, and the structural soffit.

  • Up to 120 minutes fire resistance
  • Fully qualified acoustic performance
  • Integral smoke barrier
  • Can accommodate structural service movement (during normal service life and fire)
  • Cost-effective and durable


The choice of material is determined by the performance requirement in terms of fire resistance
(i.e. insulation and integrity) and size of cavity.

The materials are manufactured using a unique manufacturing process to provide a resilient compression which ensures a tight fit.

They are either supplied as pre-cut units to suit a quoted cavity size or in sheet form for cutting on site.
