Applications:

  • Acoustic
    • RW slabs provide acoustic performance by blocking the transmission of sound within the internal structure of the slab or by absorbing the sound at the surface of the slab. This makes RW slabs ideal for sound absorption.
  • Thermal
  • Fire Protection of partition walls, Ceilings, floors & Roofs
    • All RW slabs whether faced or un-faced achieves fire properties that conform to Euro Class A1 in accordance with BS EN 13501-1. This ensure that the construction is compliant with all UK and Ireland building regulations.
