Kingspan Insulation UK and the Grenfell Tower Inquiry

Thank you for visiting. This site is intended to provide information and contacts relating to Kingspan Insulation UK's involvement as a core participant in the Grenfell Tower Public Inquiry.

The Grenfell Tower fire was a tragedy that should never have happened, and Kingspan supports the vitally important work of the Inquiry to determine what went wrong and why. We extend our deepest sympathies to the relatives and survivors of the Grenfell Tower tragedy.

We had no role in the Grenfell Tower refurbishment. However, our Kingspan Insulation UK business is a core participant in the Grenfell Tower Inquiry and fully supports the Inquiry’s important work.

We understand that this is a complex topic, but there are some important facts that we would like to explain:

1. We did not make the exterior cladding on Grenfell Tower.  The Inquiry itself has stated that "the principal reason” for rapid fire spread on Grenfell was the Polyethylene cored ACM cladding used on the exterior of the building.  No facade system using this PE ACM cladding, regardless of the insulation used, would have passed the necessary fire tests. Our K15 insulation board was misused in this unsafe and non-compliant system.

2. We did not supply or recommend K15 to Grenfell Tower. K15 made up approximately 5% of the insulation layer of the façade system. It was substituted without our knowledge.

3. We have completed new tests which support the previous fire safety claims of the three historical K15 large-scale system tests which came into question during the Inquiry process.


We condemn in the strongest possible terms the wholly unacceptable historical conduct and emails which emerged throughout the course of the Inquiry discovery process. We have sincerely apologised for these actions by a small group of employees at our Kingspan Insulation UK business. This in no way reflects Kingspan’s culture or values.

A more detailed explanation of these issues and others which have emerged during the course of the Inquiry is available in our Module 2 closing statement. A list of the extensive set of measures  put in place across our business to ensure that these historical process and conduct shortcomings can never occur again is available in our statement of February 19th. Both can be found in the Media Statements page on this site.

A dedicated team and process has been established to support any incoming queries regarding the historical use of K15 in high-rise residential buildings. You can contact them through the Technical Advice & Support page on this site.
