ROCKWOOL Rainscreen Duo Slab® becomes BBA Approved
ROCKWOOL is delighted to announce that its RAINSCREEN DUO SLAB® has become the first stone wool product to receive approval by the British Board of Agrément (BBA) for use in Ventilated rainscreen systems.
BBA certification is recognised throughout the construction industry and is a sought after accreditation for manufacturers. It is also incredibly important to specifiers, as it is a mark of quality, safety and reliability that provides reassurance of the product.
In order to achieve the BBA Agrément Certificate, products have to pass a series of comprehensive assessments, including laboratory tests, on-site evaluations, quality management checks and inspections of production. The RAINSCREEN DUO SLAB® was tested for factors such as thermal performance, condensation risk, behaviour in relation to fire, and durability in order to meet UK British Regulations. The ROCKWOOL product successfully met all these requirements and achieved certification status for use as a Hybrid frame system and Rainscreen system.
As the only stone wool product certified by the BBA for use in Ventilated rainscreen systems, this approval helps support and endorse ROCKWOOL’s key product messages:
- Peace of mind and quality of life
- Innovative products for modern life

“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. “It also reinforces the premise that we produce sustainable products that are innovative, durable and long lasting.”
