Siderise CW-FS Perimeter Barrier & Fire Stops for Curtain Walls
Description

Siderise CW perimeter barrier and fire stop systems offer an extensive range of solutions for fire stop, smoke stop and sound barrier requirements in all architectural cladding panel applications. The primary function of the CW system is to maintain continuity of fire resistance by sealing the void between the compartment floors or walls and the external curtain wall both horizontally and vertically.

Key Features
  • Market leading fire resistance and smoke seal
  • Suitable for horizontal and vertical applications
  • Unique product construction provides ability to accommodate facade movement
  • Fully qualified acoustic performance
  • Simple and quick to install
  • Standard sheet products are supplied 1200 x 1150mm which may prove beneficial when the actual void size is not known or where it varies significantly
Scope of Use

The primary function of the CW system is to maintain continuity of fire resistance by sealing the void between the compartment floors or walls and the external curtain wall both horizontally and vertically.

Limitations on Use

Siderise CW is installed using necessary compression and fixing brackets which are impaled into the material at mid thickness at nominal 600mm fixing centres i.e. 300mm from each end.

For horizontal applications the cut strips are then inserted within the void with the fixing brackets located over the edge of the concrete floor slab. The brackets must be mechanically fixed to the compartment floor or wall, with suitable non-combustible fixings. The CW is built into the void to provide the necessary compression. It’s crucial that there are no gaps.

Ensure that there are no gaps and that all joints, including the intersections of horizontal / vertical installation are tightly abutted and sealed with Siderise foil tape to ensure the integrity of the smoke barrier. As a minimum the topside is only sealed with Siderise foil tape, the juncture between facade and floor or wall need not be sealed.

A range of support brackets for Siderise CW-FS horizontal perimeter barriers are available for void widths of up to 600mm. The fixing brackets should be trimmed if necessary to approximately 75% of the cavity width. The standard fixing brackets are supplied in 1mm galvanised mild steel in flat form that is complete with a pre-notched facility for folding on site. Stainless steel brackets can be quoted and provided upon request. All holes are to be site drilled to suit the varying site conditions.

Statement of Building Code Compliance

  • Meets the 15-year durability requirements of B.2.3.1 (B) with a service life of 60+ years.
  • Siderise is unaffected by the normal conditions in a wall and is durable, water-resistant, and sufficiently stable to remain effective as a perimeter barrier and firestop.

Fire Performance – C: Clause C3.4 (a), C3.7 (a)

  • AS/NZS1530.4 & AS4072.1 - Certificate of Approval
  • Tested to EN13501-1 classied A1
  • Fire Resistance to: EN 13501-2 (EN 1364-4, EN 1366-4)
  • Tested to AS/NZS1530.1 Combustibility Test for Materials - Deemed NOT Combustible
  • Tested to AS/NZ1530.3  Simultaneous Determination of Ignitability, Flame Propagation, Heat Release and Smoke Release
In-Service History
  • Since 2016 
Other Performance Attributes

The CW range additionally provides an effective sound barrier as the material construction and inherent properties of the stone wool core afford the CW exceptional acoustic performance. Also, the foil facings coupled with the additional sealing of joints with

Siderise foil tape all serve to provide improved air tightness.

Sound reduction between floors. The installation of the CW systems within an external curtain wall cavity will significantly increase the floor-to floor attenuation. As an example, the installation of 120mm thick CW-FS120 within the cavity will increase the transmission loss via the tortuous sound path by approximately 25dB. The precise value will depend upon the specifics of the construction.
