Knauf’s Earthwool RainScreen Slab has been certified by the British Board of Agrément for use in high-rise residential applications, giving merchants more options in the rainscreen market.

The BBA certification follows the December 2018 update to Approved Document B, which mandates the use of non-combustible materials achieving a Euroclass Reaction to Fire Classification of A1 or A2 s1-d0 in the external walls of certain buildings over 18m in height. Earthwool RainScreen Slab has the best possible Euroclass Reaction to Fire classification of A1.

Steve Smith, Head of Product Management and Business Intelligence at Knauf Insulation said: “Non-combustible insulation is the best choice for architects, specifiers and contractors as it will not contribute to the development or spread of fire.”

“With the Government consulting on further changes to Approved Document B, it’s prudent to use non-combustible insulation in every application, not just high-rise façades. This BBA certificate ensures customers specifying or installing Earthwool RainScreen Slab can have absolute confidence in its quality and performance.”
