Rainscreen product is now BBA approved

Rockwool has been accredited with the British Board of Agrément (BBA) Agrément Certificate for its NyRock Rainscreen 032 product.

NyRock Rainscreen 032 is a stone wool insulation product specifically developed for use within ventilated cladding systems, as well as sealed systems such as curtain walling. Manufactured using patented technology, it has a more efficient fibre structure that increases the density of air pockets trapped within each slab. Rockwool says this results in improved thermal performance when compared with traditional stone wool products.

“Launched just a few months ago, NyRock Rainscreen 032 has already been well received by the industry thanks to the improved thermal performance it provides,” said Lisa Stephens, Product manager for the Building Envelope at Rockwool UK. “With the BBA approval, architects and designers have independent third-party confirmation of the advantages that NyRock Rainscreen 032 brings to their project.”

“The BBA provides services that drives quality and safety throughout the construction space, enabling innovation, risk mitigation, and assurance, from design through to completed build and beyond,” added Emma Wiles, Sales and Marketing director at the BBA. “It is great to see more sustainable products entering the market.”

BBA approved NyRock Rainscreen 032 has a low thermal conductivity of 0.032 W/mK. Rockwool said: “It has proven acoustic benefits, and is water-repellent, yet breathable. Being manufactured from stone wool, NyRock Rainscreen 032 is classed as non-combustible in Euroclass A1. Stone wool is dimensionally stable, and has been proven to provide the same performance for more than 55 years after installation.”
