SIDERISE EWI – Cavity Barriers and Fire Stops for External Masonry Walls

SIDERISE EWI systems have been specially developed via the incorporation of an integral intumescent, that in the event of a fire, provides a reactive method of sealing masonry wall cavities that have an irregular inner face to the outer masonry leaf.

  • Fire Resistance: EI 30 & EI 120
  • Integral intumescent
  • Up to 25mm voids / decorative features accommodated

SIDERISE EWI has been specifically developed to provide an easy to install, and effective fire, acoustic and thermal barrier for external masonry constructions.

EWI has been tested up to 425mm (horizontal) with 25mm 'air gap' to accommodate decorative features.

Designed for both masonry and steel framing system (SFS) constructions.
