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.

Rainscreen cladding systems offer a number of benefits to the building designer. Lightweight, durable and available in a huge range of materials, ventilated façade systems allow buildings to achieve their aesthetic goals whilst utilising practical construction methods.

Relevant for both new build and refurbishment projects, rainscreen cladding is a popular choice for large multi-storey buildings; however structural performance, wind loading, fire performance and thermal efficiency are all considerations for the building designer. Constructions designed with high levels of insulation benefit from reduced running costs and lower levels of carbon emissions.

Suitable for use in warm steel frame constructions or fixed directly to masonry for over cladding applications, Celotex has a rainscreen cladding solution that is successfully tested to BS 8414-2:2005, meets the requirements in BR 135 and therefore suitable for use in buildings above 18 metres in height.
