Concept Raised Access Floor Firestop Slab consists of rigid slabs of dense mineral wool faced on both sides with reinforced aluminium foil. The foil facing is printed with lines along the length to aid the fabrication of cut panels on site.

  • Manufactured in slab form or factory produced to suit specified cavity sizes
  • Upto 4 hours integrity and Insulation
  • Cavity widths from 50mm to 300mm
  • Tested in accordance with EN 1366-4, 2021

The CCL Cavity Fire Stop Slab (CFSS) range is designed for use vertically and horizontally in closed state, non-vented cavities from 50mm to 300mm.
