K15 on Grenfell Tower
Kingspan Insulation wishes to express its deepest sympathies to everyone affected by the tragic events which occurred at Grenfell Tower.
Kingspan Insulation had no role in the design or planning of the cladding system at Grenfell Tower, and provided no advice to those working on Grenfell Tower around the suitability of K15 for use in the installed cladding system.
K15 constituted 5.2% of the rainscreen insulation boards ordered for use on Grenfell Tower, and Kingspan Insulation had no knowledge that its product was being used until after the fire. The system used on Grenfell Tower was not compliant with Building Regulations, was unsafe, and should not have been used.
Large scale testing undertaken since the fire has indicated that any cladding system using the PE-cored ACM installed on Grenfell Tower would have been unsafe, regardless of insulation type. Modelling conducted since the fire by independent fire experts Efectis also supports this view.
Testing and marketing review
Kingspan Insulation has reviewed its testing and marketing of K15 and identified process shortcomings, particularly in the way certain tests of cladding systems undertaken in 2005 and 2014 were conducted and were relied upon for the marketing of K15. These shortcomings fell short of the high standards which Kingspan sets itself.
The company has now carried out extensive testing and re-testing which validates, for current K15, the BS 8414 performance claims made previously.
Although Kingspan Insulation is confident that K15 was, and is, safe for use within compliant cladding systems, these historical shortcomings should not have happened and we offer a full and sincere apology for them, and an assurance that we have made substantial changes to ensure they cannot be repeated.
Changes introduced to date include full traceability of K15, publication of all BS 8414 test reports incorporating current K15, new fire testing and accreditation protocols, and a new employee code of conduct.
We are committed to the highest standards of fire performance in our products through continuous R&D and rigorous testing, complemented by technical support and accurate product information.
Kingspan Insulation will continue to support the Inquiry’s important work to understand what happened at Grenfell, and to prevent any future tragedies of this nature. In addition, we are determined to learn all necessary lessons from the discovery of the historical shortcomings outlined above to ensure that they can never happen again.
