Siderise RV Vertical Cavity Barrier

The Siderise RV Vertical Cavity Barrier is designed to seal the void between the external envelope and internal structure in ventilated rainscreen façades. Its primary function is to prevent the spread of fire and smoke between compartments while supporting the air-pressurisation needed for the façade system to function effectively. Manufactured with a stone wool lamella core and reinforced aluminium foil faces, the barrier provides excellent fire resistance and smoke control. Its flexible construction allows it to compress and move with natural building movement, without compromising performance throughout the building’s life. This makes it ideal for high-performance façades where airtightness, compartmentation and fire safety are essential.
