Description

Rocksilk® Soffit Linerboard Standard is a rock mineral wool slab, designed to insulate non-exposed structural soffits in applications such as underground car parks.

It is non-combustible with the best possible Euroclass A1 reaction to fire classification, and is manufactured using our unique bio-based binder, ECOSE® Technology.

Benefits

  • Available both unfaced and with a black tissue facing, for use in non-exposed soffit applications.
  • Provides a solution to upgrade thermal performance of existing floors without reducing floor height.
  • Can be installed without the need to access areas above the floor.
  • Manufactured from mineral wool which provides the best levels of sound absorption and reduction compared to other mainstream insulants to reduce the sound transfer between storeys.
  • Available with optional fixings which match the colour of Rocksilk® Soffit Linerboard Standard and Extra.
