Mr. Seán Armstrong:

The Sustainable Energy Authority of Ireland, SEAI, is responsible for the grant scheme for the private sector, but the works are carried out in accordance with the building regulations. Part D of the building regulations requires that external insulation systems are third-party certified, which is typically National Standards Authority of Ireland, NSAI, Agrément certified in Ireland. That would test external wall insulation systems for all parts of the building regulations, including severe weather exposure. All the materials would have been tested for that. The NSAI operates a database of materials that have been tested, and there would be trained installers. The authority would audit the installer schemes for those systems. The grant scheme would require that the works would be carried out in accordance with building regulations, and the NSAI would operate a certification system to ensure that they are in accordance with the building regulations.
