SIDERISE Cavity Barriers in Ventilated Facades

RH & RV

Siderise RH and RV ‘Open State’ cavity barriers have been specifically developed to meet the requirements for cavity barriers used in drained and ventilated façades. The system design ensures that the system will drain moisture and maintain airflow in the façade cavity.

In the event of fire the system will bloat, tightly sealing the façade cavity providing highly effective hot smoke and fire barrier.

Siderise RH ‘Open State’ horizontal and RV vertical cavity barrier range represent the default choice for market leading, high-performance Rainscreen Cavity Barrier applications.
Allows continuous ventilation and drainage behind the external envelope.
Reactive intumescent has rapid seal closure properties
Horizontal barriers can incorporate up to 50mm continuous ventilated air space.
Vertical barriers accommodate cladding serviceability movement
Products tested in isolation and in large-scale system tests

Siderise RH Horizontal cavity barriers: Siderise has developed two ‘Open State’ (open void) horizontal solutions:
- RH25(G/S) for air gaps up to 25mm
- RH50(G/S) for air gaps up to 50mm
The product range is compliant to current market requirements and has been tested to ASFP Guidance: ‘Open State’ Cavity Barrier used in External Envelope or Fabric of Buildings, utilising principles of EN 1363-1.
- Refer to ASFP Technical Guidance Document – TGD 19 (July 2014 revised Nov 2017).
Siderise RV vertical cavity barriers for rainscreen cladding are used to full fill the void between the external envelope and internal structure.
By fully sealing the void they assist ventilated façades to function by maintaining air-pressurisation compartmentation.
Their unique stonewool lamella core construction enables the vertical barriers to accommodate the serviceability movement normally associated with rainscreen façades.
Intersections between horizontal and vertical cavity barriers are simply abutted.
