Celotex Reaches New Heights


The UK’s leading manufacturer of PIR insulation, Celotex, has once again demonstrated its innovative credentials with the launch of Celotex RS5000, a new premium performance PIR solution specifically designed for rainscreen cladding applications.

The latest addition to the ‘5000’ series product range, Celotex RS5000 has successfully tested to BS 8414-2:2005, meets the criteria set out in BR 135, and therefore is acceptable for use in buildings above 18 metres in height.

Suitable for use in domestic and non-domestic applications for either new build or refurbishment projects, Celotex RS5000 can be used in warm steel frame constructions or fixed directly to masonry for overcladding applications.

Supported by LABC Approval, Celotex RS5000 leverages the market leading PIR manufacturer’s pioneering thermal performance of 0.021 W/mK as well as offering Class O fire performance.

“Celotex RS5000 is the first PIR board to successfully test to BS 8414 making it acceptable for use in buildings above 18 metres in height,” said Jon Roper, Product Manager for Celotex. “As a company, we are always looking to innovate and develop solutions for new applications. RS5000 will allow contractors, architects and specifiers to use premium performance PIR in externally cladded walls for the first time in high-rise constructions”.

With the addition of Celotex RS5000 to an unrivalled PIR insulation product range, Celotex products achieve better U-values with thinner solutions.
