Question to the Department for Levelling Up, Housing & Communities:

To ask the Secretary of State for Housing, Communities and Local Government, pursuant to the Answer of 18 March 2019 to Question 232023 and the Answer of 4 February 2019 to Question 214563 on Buildings: Insulation, whether his Department has analysed the non-Aluminium Composite Material samples held at the Building Research Establishment to establish how many are High Pressure Laminate-B with stonewool.

The screening programme set up after the Grenfell fire tragedy was focussed on identifying and the types of aluminium composite materials received. 1,421 samples of other materials were also submitted but these were not suitable for the screening tests. A detailed explanation of the screening tests is set out in this note published in June 2017. https://www.gov.uk/government/publications/explanatory-note-on-safety-checks-and-testing.

The non-Aluminuim Composite Materials (ACM) samples were catalogued but it is not possible given their size and condition to reliably identify and classify each sample. These samples would not provide reliable or representative indication of the materials currently present on the existing building stock, this is because only those buildings with ACM cladding systems were asked to submit samples.

I refer also to my answer of 24 January to question UIN 210599.
