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.
