The Ministry of Housing, Communities and Local Government (MHCLG) has written to building control bodies including in local authorities across England and Wales to alert them to the retraction of three tests carried out on Kingspan K15 insulation.
This followed a letter from Kingspan to the Building Research Establishment (BRE) dated 23 October 2020 which was published by the Grenfell Tower Inquiry. It recognised that the products placed on the market were different to the products tested, and that there were inaccuracies in the test reports.
The letter, which can be found at GOV.UK, requires fire safety professionals and buildings control bodies to review their records.
They must, it points out, check that any assessments (direct, extended application or fire engineering assessment) they have carried out using these tests are identified and revisited in light of the announcement about Kingspan.
The retracted tests relate to:
K15 + cement particle board carried out in 2005 (Test Report No 220876 carried out to BS 8414-1; dated December 2005, Classification Report No P101812-1000)
K15 + “standard” HPL carried out in 2014 (Test Report No 293940 carried out to BS 8414-2; no classification due to early termination)
K15 + terracotta tiles carried out in 2014 (Test Report No 297099 carried out to BS 8414-2; Classification Report No 291642).
Fire safety professionals or building control bodies should confirm whether any were supplied on projects where the assessment has been relied on and, where necessary, contact the relevant clients or building owners to inform them of the situation, the MHCLG concludes.
