- Full cavity fill every time.
In most homes we have insulated throughout Ireland we have encountered problems with insulation boards not installed correctly in most cases the gaps between the boards were between 3mm and 10mm!.With the insulation boards installed incorrectly there was a loss of between 150% and 200% off the calculated u value of the walls.
Korefill is the ideal insulation solution for Domestic and Commercial customers for new build or retrofit projects. Contact Capital Insulation for a free survey and advice on the best insulation solution to suit your needs and budget.
KOREFill 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. KOREFill insulating mass significantly reduces thermal transmittance across the cavity. Filling the cavity with KOREFill still allows the cavity to preform its function. The cavity will still be able to breath, the bead does not absorb water and water will not transfer across the cavity to the inner leaf.
