Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Communities and Local Government, what plans he has to include phenolic foam in fire safety tests of cladding and insulation materials being undertaken in response to the Grenfell Tower fire.

Our statement of 6 July set out the approach we are adopting.

The 2 insulation materials recommended by the expert panel for use in the full testing were rigid polyisocyanurate foam (PIR) and non-combustible mineral wool. There are many types of rigid foam insulation boards available and PIR was considered to be the most appropriate option for purposes of this series of tests.
