This open letter provides clarity on the standards required for the installation of room-in-roof insulation (RIRI) under ECO2t.
In order to claim that a RIRI measure has been installed in accordance with PAS 2030: 2014 Edition 1 or PAS 2030: 2017 Edition 1 from 1 April 2017 (the beginning of the ECO2t period), we expect that the installation of a RIRI is in line with the manufacturer’s instructions and the prescribed installation methods for the product used.
