Insulation industry news from Global Insulation

UK: Knauf Insulation’s Earthwool RainScreen Slab product has been certified by the British Board of Agrément (BBA) for use in high-rise residential applications. 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.

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

UK: The British Board of Agrément (BBA) has given its approval to Rockwool’s Rainscreen Duo Slab façade insulation product. It is the first stone wool product to gain this for use in ventilated rainscreen systems. As part of the certification process the product was tested for factors such as thermal performance, condensation risk, behaviour in relation to fire, and durability in order to meet national regulations. Rainscreen Duo Slab has achieved certification status for use as a Hybrid frame system and Rainscreen system.

“It is incredibly important to us to put our products through the BBA process, as the certification provides architects with peace of mind when specifying our products” comments Paul Barrett, Product Manager at Rockwool.
