Certificate type
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.
Application
Suitable for providing a seal between the top of the compartment wall, partition, fire-resistant suspended ceiling, and the structural soffit. The performance requirement determines the choice of material in terms of fire resistance (i.e. insulation and integrity) and size of the cavity.
Uses include:
- Fire-stopping voids above compartment walls and partitions up to 400mm depending on the fire performance required.
- As an acoustic barrier at tops of walls
Description
Siderise firestops for tops of walls comprise a single, close dimensioned product with a unique pre-compressed internal stonewool mineral fibre lamella core.
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.
The range of Siderise firestops for tops of walls includes various types of products which are referenced ‘TW’ to designate the ‘Tops of Walls’ application. The materials have been developed and tested at various thicknesses to meet the fire and acoustic performance requirements.
Features and benefits:
- Class ‘A1’ in accordance with EN13501-1.
- Ease of installation.
- Provides an acoustic barrier at tops of walls
- The products have integral aluminium foil facings and are a functional smoke barrier.
- Can accommodate structural service movement (during normal service life and fire).
