Cavity Wall Insulation Cost Savings

The following example shows the average cost savings when choosing KORE Fill Cavity Wall Insulation over rigid board PIR insulation. The costings took into account a semi-detached house with a wall area of 137m2 to achieve a U-value of 0.18W/m2K.

Even with a wider cavity (170mm) the cost savings on average is 27%. This figure does not include the cost savings associated with skip hire and waste removal associated with rigid board insulation.

KORE Fill Psi Therm Logo

KORE Fill Psi Therm is manufactured from Expanded Polystyrene Insulation and designed to be installed in a cavity wall below the damp proof course (DPC) level. The product eliminates the thermal bridge at the wall-to-floor junction.

The benefits of KORE Fill Psi Therm include:

  • Eliminates the wall-to-floor thermal bridge
  • Extends cavity insulation below floor slab level
  • Improves Psi value
  • Inherits all the benefits of EPS, including water and moisture resistance and is unaffected by air infiltration
  • Can be fully recycled at the end of its useful life
  • Site specific to the required sizes and dimensions
