We were shocked by the tragic events of the Grenfell Tower fire. Our thoughts remain with everyone affected by this devastating human tragedy. We want to do everything that we can to support the Government’s ongoing response and continue to offer our full cooperation with the investigations.

Our records show that we sold a quantity of a PIR (Polyisocyanurate) insulation product, Celotex RS5000, through distributors and our understanding is that this was for on-sale and for use in the Grenfell Tower refurbishment project in 2015.

We did not install any of the materials in Grenfell Tower and Celotex do not manufacture, supply or install cladding.
We have been supplying building products since 1925 and supplying PIR for over forty years. As a business our focus has always been to supply safe insulation products to make better buildings.

Our records show that we sold a quantity of RS5000 through distributors which we believe was for on-sale to use in the Grenfell Tower refurbishment project in 2015.

RS5000 is a PIR insulation product for use in multicomponent rainscreen cladding systems on buildings with a storey height of above 18m. Fire safety testing was undertaken on RS5000 as part of a particular rainscreen cladding system and this is described in documents available on our website and this microsite.

The reasons why the Grenfell fire spread as it did are currently unclear but will be established through the various investigations and inquiries which are underway. These investigations and inquiries will consider a broad range of factors, such as the building construction and the fire safety measures in place. It is not simply the choice of materials but the construction of the building and the way in which all components of the rainscreen cladding system have been used which will be important.

Following the Grenfell fire, we checked our records and made an announcement as soon as we understood that we had supplied PIR insulation panels through distributors for the Grenfell Tower refurbishment.

We have made clear that we will fully co-operate with all enquiries from the relevant authorities.

On 23 June 2017, in view of the focus on components of rainscreen cladding systems, we felt that the right thing to do was to stop the supply of Celotex RS5000 (including in respect of ongoing projects), pending further clarity. We will consider carefully the results of the series of ongoing DCLG tests into aluminium composite material rainscreen cladding systems in this context.
