Siderise RH25 cavity barrier system represent the default choice for market leading, high performance, ‘Rainscreen Cladding Cavity Barrier’ applications.
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.
Siderise RH25 ‘Open State’ horizontal cavity barriers 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 25mm.
Note: This product was previously known as ‘Lamatherm CW-RS’.

- Horizontal barriers can incorporate up to 25mm continuous ventilated air space
- Vertical barriers accommodate cladding serviceability movement
Siderise RH ‘Open State’ horizontal cavity barriers have been specifically developed to meet the requirements for cavity barriers used in drained and ventilated façades. Their use ensures that the system will drain any moisture within the façade construction whilst maintaining airflow and, in the event of fire, provide an effective hot smoke and fire seal.
As standard, the range includes a choice of products to suit 25mm air gaps – referred to as RH25. They are available with either galvanised mild steel (G) or stainless steel (S) fixing brackets as part of the system. The specific horizontal cavity barrier system is then referred to as either RH25G or RH25S. The choice of bracket is usually determined by the rainscreen system designer according to project exposure and/or location.
