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.

Statement immediately following Grenfell Tower Fire regarding use of RS5000

Categories: Historical Statements, RS5000

As with the rest of the nation our thoughts continue to be with those affected by the terrible fire at Grenfell Tower in London. On Wednesday, as soon as we were able to, we confirmed that our records showed a Celotex product (RS5000) was purchased for use in refurbishing the building. We wanted to provide an update to that statement and provide further information as we are able to.

It is important to state that Celotex manufacture rigid board insulation only. We do not manufacture, supply or install cladding. Insulation is one component in a rainscreen system, and is positioned in that system behind the cladding material.

As we previously stated, our records show a Celotex product (RS5000) was purchased for use in refurbishing the building. This product has a fire rating classification of Class 0, in accordance with British Standards. Celotex RS5000 is the insulation component specifically tested as part of a system to British Standard BS8414-2:2005. When the system is designed and installed in line with this, RS5000 meets the criteria set out in BRE Report BR 135 ‘Fire performance of external thermal insulation for walls of multi storey buildings.’

We will of course assist the relevant authorities fully with any enquiries they have.
