Celotex and Grenfell Tower: Updates and information

The Grenfell Tower fire in June 2017 was a terrible tragedy. Celotex, and the Saint-Gobain Group, reaffirm their deepest sympathies to everyone who has been and continues to be affected by the fire.

This site provides information on Celotex’s RS5000 product and on Celotex’s participation in the Grenfell Tower Inquiry.

The Inquiry hearings concluded with closing statements in November 2022 and the Inquiry is expected to publish its Phase 2 report in 2023. Celotex, with the support of the Saint-Gobain Group, has cooperated fully with the Inquiry in order to find out what happened and to ensure it does not happen again.

Since the Grenfell Tower fire, Celotex has undertaken a review of its process controls, quality management and approach to marketing to address issues discovered as part of its investigations following the Grenfell Tower fire and ensure that no such issues reoccur. Celotex recognises that this is an ongoing process. It is committed to continuous improvement.

How were Celotex products used?

In 2014 Celotex supplied PIR insulation known as RS5000, through distributors, which was one of the components used in the Grenfell Tower rainscreen cladding system. Celotex does not design or install cladding systems and did not do so at Grenfell Tower.

In the days immediately after the fire Celotex discontinued the sale of RS5000 on a precautionary basis. Celotex subsequently also made the decision not to supply any insulation product for use in rainscreen cladding systems on buildings over 18 metres.

A second Celotex PIR insulation product, TB4000, was supplied through third-party distributors and was found on Grenfell Tower. TB4000 is a general-purpose insulation product.
