Update - IMPORTANT: On 23 June 2017, in view of the focus on components of rainscreen cladding systems, Celotex stopped the supply of Celotex RS5000, pending further clarity.  RS5000 remains suspended. Celotex do not currently supply a solution for buildings over 18 metres.

In December 2017 we identified a compliance issue relating to our calculation and testing of the lambda value of products in our 4000 and 5000 range and the Crown-Bond and Crown-Fix products within Crown Flat Roofing range. Material such as product downloads & specifications is for information only. 

On 30 January 2018, Celotex made a further public announcement in relation to the full system testing of RS5000 pursuant to BS8414:2.  The announcement can be read here
