Siderise launches dedicated precast range
Siderise has launched the PC-FS Firestop and PC-CB Cavity Barrier range, described as the UK’s first commercially available passive fire protection package developed specifically for precast concrete cladding systems.
Siderise said it previously supported precast concrete façade applications with its CW-FS Firestop and reapproached the application in response to demand for these external wall systems.
The new range was developed as a dedicated solution for systems with tight tolerances and limited access.
It was also developed to address difficult interfaces and construction sequencing.
Product design and fire test details
The stone wool Lamella core provides built-in compression and uses a bracket-free fix for narrow voids.
Siderise said this contributes to faster installation times when compared with less compressible barriers.
PC-FS Firestop and PC-CB Cavity Barrier can also be fitted from above or below the slab.
The company said this supports projects where topside access is restricted or where sequencing requires a different installation route.
Both products are tested to EN 1366-4 and EN 13501-1 standards.
Siderise also cited supplementary fire test evidence for precast concrete panel bracket penetration and end of flexible wall configuration.
The supplementary evidence also covers firestop bracket securement to the underside of the slab edge.
Fire resistance and technical support
The firestopping products PC-FS60 and PC-FS120 offer third-party certified 1 hour and 2 hours of fire resistance respectively.
The cavity barrier PC-CB30 offers 30 minutes.
Siderise said the range is supported by technical services and specification resources.
These include a specification pack with technical information and guidance on joints and complex details such as blade column interfaces and other challenging geometries.
