Siderise RF Cavity Barrier and Firestop subdivides large uninterrupted voids (cavity barrier) or provides continuity of fire resistance (firestop) when aligned beneath internal walls to prevent fire and heat spread under raised access floors. It also functions as an acoustic treatment for airborne flanking noise paths to protect privacy, foster productivity, and promote harmony and well-being. It can also be used as a plenum liner.

Siderise RF Cavity Barrier and Firestop features a factory-engineered stone wool Lamella insulation with foil facings applied to the cut surfaces of pre-compressed vertically oriented fibres to retain the ‘built-in compression’. This allows it to tolerate live loads and slab deflection and deliver a secure fit for long-term reliability.
