KORE Fill
KORE Fill is a bonded bead, complete cavity wall fill insulation system for application in new and existing buildings. KORE Fill is expanded polystyrene and special bonding agent injected in bead form into a cavity to form an insulating mass.
KORE Fill is expanded polystyrene injected in bead form into a cavity to form an insulating mass. The bead solidifies in the cavity as it is injected along with a special bonding agent. This insulating mass significantly reduces thermal transmittance across the cavity. Filling the cavity completely with KORE Fill will not diminishthe original function of the cavity. The cavity will still be able to breath, the bead will not absorb water and will not allow the transfer of water across the cavity to the inner leaf. Advantages:

- Immediate savings on heating bills
- Installation complete in one day
