Siderise Cavity Barriers For Rainscreen Cladding

Siderise cavity barrier system represents the default choice for market-leading, high performance, ‘Rainscreen Cladding Cavity Barrier’ applications.

Siderise RV Cavity Barriers are used to full fill the void between the external envelope and internal structure. The construction offers excellent resistance to the passage of both smoke and fire. Siderise Additionally, by fully sealing the void, they assist ventilated façades to function by maintaining air-pressurisation compartmentation.

Suitable for vertical (full seal) applications

Up to EI 120 minutes of fire integrity/insulation

Tested to EN 1366-4

Third-party approved (Certifire CF 6028)

Siderise RH cavity barriers

Siderise Importantly, the Siderise RV vertical cavity barriers unique stonewool lamella core construction enables the vertical barriers to accommodate the serviceability movement normally associated with rainscreen façades.

Siderise RH/RV cavity barrier system represent the default choice for market leading, high performance, ‘Rainscreen Cladding Cavity Barrier’ applications.

Siderise Used in the external envelope or fabric of buildings, they ensure the system will drain freely, whilst maintaining airflow and providing an effective hot smoke and fire seal.

IFC Certified (IFCC 1712)

Siderise Allow continuous ventilation and drainage behind the rainscreen envelope

Tested to ASFP TGD19 ‘Fire Resistance Test of Open State Cavity Barriers’ utilising BS EN 1363-1 and Principles of BS EN 1366-4

Up to 120 minutes fire integrity

Suitable for horizontal (open void) applications

All horizontal cavity barriers are colour-coded for ease of identification



Siderise RH horizontal cavity barriers

Siderise Incorporates a continuous bonded intumescent strip to the leading edge and encapsulated in a weather-resistant polymer film. In the event of exposure to fire, this expands and fully seals the designed ventilation gap formed at the time of installation between the barrier and the rear of the cladding, in compliance with CWCT and NHBC guidance for air gaps up to 50mm.
