Siderise Passive Fire Protection

Cavity Barriers

Siderise RH/RV cavity barrier systems have become the default choice for market-leading, high performance and comprehensive external fire protection internationally.

Located within the drained and ventilated cavity of the external envelope, they ensure the system will drain freely whilst maintaining adequate airflow and providing a fast and effective fire protection barrier. The Siderise Rainscreen Cladding Cavity Fire Barriers offer application options to ensure full compliance with NZBC C/AS2:5.8.5. Installation is easy with either proprietary brackets or screw fixing. Due to some site conditions being variable these systems are also designed to be modifiable to allow for building tolerances. By designing the system with these variances in mind Siderise can deliver a safe option for almost any standard façade or cladding system.

Key Features

• Site Modifiable
• Allows continuous ventilation and drainage behind the external envelope
• Products tested extensively in small-scale/individual material tests as well as in full-scale system tests for a number of façade systems
• Reactive intumescent band has rapid seal closure properties
• Horizontal barriers can accommodate up to 50mm continuous ventilated air space
• Vertical barriers accommodate cladding serviceability movement 

Perimeter Fire Stop for Curtain Wall

Siderise CW-FS (Curtain Wall Fire Stop) systems are a proven means to protect the slab edge perimeter behind a curtain wall from the spread of fire, smoke and sound. Ensuring that the performance of the slab is extended all the way to the back of the spandrel panel. The adaptive, clean and easy-to-install system provides guaranteed movement capabilities, meeting and exceeding NZBC C/AS2:4.15.3 requirements

Siderise CW-FB (Curtain Wall Fireboard) A Spandrel protection infill that forms part of a perimeter barrier firestop and spandrel zone protection system for use with non-fire rated aluminium curtain wall façades.

CW-FB and CW-FS (Perimeter Barrier and Fire Stop Systems) have been jointly tested in conjunction with non-fire rated aluminium curtain wall assemblies to provide market leading fire resistance performance for the critical spandrel zone.

Siderise CW-FS system is tested to BS EN 1364-4*. The New Zealand Acceptable Solution C/AS2 or Verification Method C/VM2 does not specify a test standard or method of testing for a curtain wall firestopping system, however MBIE have suggested to BS EN 1364-4 as an acceptable test method for demonstrating compliance. *SIDERISE is also tested to BS EN 1366-4 horizontally and vertically.
