BS 8414 Documentation

In 2018, ROCKWOOL conducted a BS 8414 test on a generic rainscreen system incorporating Rockpanel Durable cladding and ROCKWOOL Duoslab insulation, in response to requests from the market. The test was conducted at the Al Futtaim Exova (AFE) laboratory in Dubai, a UKAS accredited institution. This system passed the test on all criteria and was classified to BR 135.

The system tested does not duplicate the specific design of any particular building, and all buildings using rainscreen systems should be checked for proper installation of materials.

ROCKWOOL does not support the use of the BS 8414 test and BR 135 classification criteria to assess the fire safety of high-rise buildings. We recommend that buildings over 18 metres and all high-risk buildings with rainscreen systems use only cladding and insulation with a European reaction to fire classification of A1 or A2.

In the interest of transparency, we have posted the classification report and test report here, confirming that the system passed the test.
