Flux Fire Protection specialises in the supply and installation of Siderise façade cavity barrier systems for commercial, residential and mixed-use developments across the UK.

Siderise & Facade Cavity Barrier Installers
At Flux Fire Protection we work with world‑leading manufacturers to deliver high-performance, tested passive fire protection systems. We work with leading manufacturers such as Siderise — a brand renowned for its rigorously tested fire, acoustic, and thermal solutions.
Siderise & other façade cavity barriers are designed to provide fire compartmentation within ventilated and non-ventilated façade systems. Installed within concealed cavities behind rainscreen cladding, curtain walling and other external façade systems, they are engineered to restrict the spread of flames, smoke and hot gases while maintaining the performance requirements of the building envelope.
Manufactured from high-performance stone wool with specialist fire-resistant facings, Siderise façade cavity barriers have been extensively tested for use within a wide range of façade constructions and are trusted on projects throughout the construction industry.
