Description

Cavity barriers for drained and ventilated facades, available for vertical or horizontal applications. 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.

Features and benefits:

  • Allows continuous ventilation and drainage behind external envelope.
  • Provides up to 120 minutes' fire integrity and 90 minutes' insulation.
  • Rapid seal closure times.
  • Fully compliant and meets ASFP guidelines.
  • Suitable for both horizontal and vertical applications.
  • Horizontal barriers can incorporate up to 50 mm continuous ventilated air space.
  • Vertical barriers accommodate cladding movement.
  • Tested to EN 1364-6:2016.

SIDERISE RH Open State Horizontal Cavity Barriers (formerly Lamatherm CW-RS):

This consists of a non-combustible stonewool lamella core, with reinforced aluminium foil faces, giving an overall reaction to fire performance to Class A1. The exposed leading edge is also sealed with aluminium foil. Whilst the base material is water repellent and non-hydroscopic, this predominantly enclosed arrangement affords an added degree of weather protection to the core material.

SIDERISE RH ‘Open State’ horizontal cavity barriers incorporate a continuous high performance reactive intumescent strip which is bonded to the leading edge. The intumescent material has a reaction to fire performance to Class 'E'. In the event of exposure to fire, the intumescent rapidly expands and fully seals the purposely designed ventilation gap, formed at the time of installation, between barrier and the rear of the cladding.

SIDERISE RV Vertical Cavity Barriers (formerly Lamatherm CW-RS):

This consists of a non-combustible stonewool lamella core, with reinforced aluminium foil faces, giving an overall reaction to fire performance to Class A1. They are used to full fill the void between the external envelope and internal structure. The construction offers an excellent resistance to the passage of both smoke and fire. Additionally, by fully sealing the void, they assist ventilated facades to function by maintaining air-pressurization compartmentation.

The stonewool lamella core construction enables the vertical barriers to accommodate the serviceability movement normally associated with rainscreen facades. The leading edge compresses directly against the external envelope. No intumescent strip is required.
