As demand for faster, more efficient construction grows - combined with the increasing trend for a brick finish in mid- and high-rise developments – mechanical fix brick slip cladding systems have emerged as a contemporary, lightweight, and versatile alternative to traditional masonry external wall systems that use full-depth bricks.

The Siderise RH & RV Brick Slip Cavity Barrier System is an adaptation of the Siderise RH & RV Rainscreen Cavity Barrier system to provide a re-engineered passive fire solution that suits the specific design features and intricacies of different brick slip façade manufacturers’ systems.

Siderise RH Brick Slip Horizontal Open State Cavity Barrier: Balancing ventilation and drainage with fire compartmentation

Siderise RH Brick Slip Horizontal Open State Cavity Barrier comprises a stone wool lamella core with vertically oriented fibres and an intumescent strip on its leading edge encapsulated within a colour coded polymer film.

In normal service conditions, it allows ventilation and drainage of the cavity by leaving a gap behind the outer brick slip skin but closes the cavity in the event of fire to provide fire separation. The intumescent layer activates at around 130°C and starts to exfoliate until it fully closes the gap to form an effective fire seal within 5 minutes.

Siderise RV Brick Slip Vertical Cavity Barrier: Configured for compatibility

Siderise RV Brick Slip Vertical Cavity Barrier bridges the cavity between the external cladding and inner wall structure to form compartments for confining fire, as well as limiting air movement behind the cladding to create a pressure-equalised cavity.

Its adaptability, underpinned by expert technical guidance, helps overcome the fire safety, moisture egress and ventilation challenges presented by irregular cavity sizes and the troublesome voids created by the brick slip rails and the indentations of frogged brick tiles. The pre-compressed stone wool Lamella expands upon cutting to seal the gaps, contributing to a methodical build process.
