Cavity Wall Insulation is used to reduce heat loss through a cavity wall by filling the air space with a porous material. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs.
During construction of new buildings, wall cavities are often filled with glass fibre wool or rock wool panels placed between the two sides of the wall, but many other building insulation materials offer various advantages and many others are also widely used. A cavity wall consists of two rows of brick or concrete block with a cavity or
space between them. Injection of insulating product from the outside is the
best method for insulating this type of wall.
For existing buildings that were not built with insulated cavities, we use the Korefill Silver Bonded Bead Insulation to fill the wall cavity.
In Ireland, Wall Insulation Grants from the Government through the SEI are widely available to help with the cost of Cavity Fill Insulation (up to €400).
KORE Fill is a bonded bead, complete Cavity 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 wall to form an insulating mass.
Only fully trained KORE Fill installers may install the cavity wall insulation. Each KORE Fill installer is registered with the Irish Agrement Board (IAB) and undergoes continuous monitoring by both Airpacks Ltd. and the IAB
For existing buildings KORE Fill is installed from the outside of the building through drill holes. Upon completion, the installer will fill the holes. For new buildings, the KORE Fill is installed from the inside of the building, once the building has been sealed from the elements.
The natural matrix formed by the bead means that the moisture that penetrates the outer leaf will not travel through the wall cavity to the inner leaf. The water by natural gravity will flow to the weep holes at the bottom of the cavity. The beads bond together in a honeycomb type of formation allowing air to circulate and the cavity to breathe.
Yes. Your installer will insert a special brush during installation to prevent bead from entering the neighbouring wall. The brush is removed when the bead solidifies.
