SIDERISE OSCI Open State Cassette Insert
Description

SIDERISE Open State Cassette Inserts (OSCIs) are designed for use in cassette panel cladding systems.

OSCI can be used horizontally or vertically as part of a cladding system. They are applied directly to the internal surface of the cassette panel to simplify the detailing and installation of adjacent cavity barriers and/or to ensure that the ventilation air gap is dimensioned within permissible limits.

SIDERISE OSCI products are manufactured from strips of high-density non-combustible stonewool (Class A1) with foil-facings on two sides. One side has an additional high-performance modified acrylic pressure-sensitive adhesive with strippable film.​

Features and benefits:

  • Tested in multiple BS 8414 & NFPA 285 system tests.
  • Can be used in combination with either RH25 or RH50 (horizontal), or RV (vertical) cavity barriers.
  • Range of thicknesses and widths to accommodate a wide array of Cassette Panel Cladding Systems.
  • Classified A2-s1, d0 to EN 13501-1.
