PDF_small.png For up to date technical information about KORE Fill Cavity Wall Insulation please download our Design Guide or review the benefits of installing cavity wall insulation.

U-VALUE CALCULATIONS

The following are example U-value calculations for new buildings. KORE Fill with a thermal conductivity of 0.035W/mK and KORE Fill X 0.033W/mK are displayed in the calculations. For U-value calculations specific to your project please contact our technical team today.

Thermal Resistance

Thermal resistance, known as the R-value, varies with the thickness of insulation. To calculate the thermal resistance (m2.K/W) divide the thickness of the insulation by its thermal conductivity and round down to the nearest 0.05.

Buildings Standards

KORE Fill can satisfy the requirements of the Irish Building Regulations as outlined in:

  • Part L - Conservation of Fuel and Energy - Dwellings (2011)
  • Part L - Conservation of Fuel and Energy - Buildings other than Dwellings (2008)

The following standard should be consulted regarding the construction of insulated cavity walls:

  • BS 5628-1:2005
  • BS 6528-2:2005
  • IS EN 1996-1-1:2006 Eurocode 6

KORE Fill Bonded Bead is manufactured to BS EN 13163:2012 under Quality Management System approved to EN ISO 9001:2008 Quality Management.

INSTALLATION

KORE Fill Cavity Wall Insulation bead and bonding agent are injected into the cavity, through drill holes, using specifically designed equipment. The KORE Fill certified drilling pattern ensures that the entire cavity is completely filled. Installation of KORE Fill Bonded Bead product must only be carried out by KORE or one of our NSAI trained and approved installers. For details of your local installer or our installation manual please contact our team today. Consult our KORE Fill Installers Register for approved and certified KORE Fill bonded Bead installers across Ireland and the UK.

New Buildings

For specification purposes the exposure zone of the building must be assessed. Further details can be found in our NSAI Agrement Certificate Number 07/0293. Buildings must be assessed in accordance with BS 8104:1992 Code of Practice for assessing exposure of walls to wind driven rain together with information provided by the Irish Meteorological Office. Please contact our technical team for further information. The buildings must be surveyed in full by a trained, competent KORE Fill installer prior to verify the suitability for KORE Fill Bonded Bead.

Existing Buildings

The suitability of an existing building must be examined by a trained, competent KORE Fill installer. Where a building is older than 3 years and there is no evidence of moisture ingress or dampness on the internal walls the buildings need not be assessed in accordance with BS 8104:1992 Code of Practice for assessing exposure of walls to wind driven rain. In the case of fair faced brickwork recessed mortar joints are not suitable for filling. Only tool flush joint brickwork is acceptable, subject to the following conditions: the minimum cavity is 40mm, there is no sign of dampness on the inner face of the cavity, mortar joints are in good condition and free from defects which may allow water ingress.
