Precast concrete façade fire safety addressed by Siderise

Siderise previously supported precast concrete façade applications with its CW-FS Firestop, delivering a fully compliant solution. However, due to growing demand for these durable and efficient-to-build external wall systems, Siderise reapproached this application to develop a dedicated solution that has been comprehensively tested, while also addressing the practical challenges associated with these systems (such as tight tolerances, limited access, complex interfaces and construction sequencing).

The stone wool Lamella core provides built-in compression and, alongside a bracket-free fix for narrow voids, contributes towards faster installation times when compared to less compressible barriers.

The PC-FS Firestop and the PC-CB Cavity Barrier can also be fitted from above or below the slab, making them ideal where topside access is restricted or when sequencing requires alternative installation approaches.

EN 1366-4 and EN 13501-1

Both products are tested to EN 1366-4 (resistance to fire) and EN 13501-1 (reaction to fire) standards, with supplementary fire test evidence for precast concrete panel bracket penetration, end of flexible wall configuration and firestop bracket securement to the underside of the slab edge to support a wider range of project conditions.

The fire stopping products, specifically PC-FS60 and PC-FS120, offer third party certified one and two hours’ worth of fire resistance respectively, with the cavity barrier (ie PC-CB30) offering 30 minutes.

As is true of all Siderise solutions, the PC-FS Firestop and PC-CB Cavity Barrier are supported by comprehensive technical services and a suite of resources designed to assist with the specification process (including a specification pack containing all necessary technical information as well as guidance on joints and complex details, such as blade column interfaces and other challenging geometries).
