Letter to building control bodies on the retraction of three tests carried out on Kingspan K15 insulation

The retraction of three test reports by Kingspan Insulation Ltd means that fire safety professionals and buildings control bodies should review their records to 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 Kingspan’s announcement.

It is also important that fire safety professionals fully consider the tests that failed to achieve a BR135 Classification via a BS8414 test, which are now published on the Kingspan website.

Where they identify an assessment, which relies on the information provided by these tests, fire safety professionals and building control bodies should make all reasonable efforts to revisit the conclusions of their assessment and that the materials used are appropriate.
