Description

SIDERISE EW systems comprise a low resin content stone wool insulation core, which is pre-compressed internally to form a resilient strip. The material is faced on two sides with a reinforced aluminium foil which is an effective smoke barrier.

Features and benefits:

  • Class A1 to EN 13501-1.
  • Fire resistance: Up to two hours (E 120/ I 120) to EN 1366-4.
  • Third party approval – Certifire CF 5727.
  • Sound reduction: Up to 25 dB (Rw).
  • Integral smoke barrier.
  • Resilient to accommodate site tolerances without cutting.
  • Friction fit options for green brickwork installation.
