Knauf Insulation’s Rocksilk® EWI Slabs

Knauf Insulation is proud to announce that its Rocksilk® EWI Slab and EWI Slab Plus have become the first and only insulation products to be awarded a standalone Agrément certificate by the British Board of Agrément (BBA) for use in External Wall Insulation (EWI) applications. This groundbreaking certification marks a significant milestone for the insulation industry and offers transformative benefits for system holders and installers alike.

Unlike traditional BBA Certificates for EWI, which are typically issued for full EWI systems, this certification exclusively covers the insulation slabs. This innovative approach simplifies the certification process for EWI System Designers, providing them with a BBA-approved insulation solution that streamlines their own system certifications.

“This is an exciting first for the industry,” said Luke Davies, Rock Mineral Wool Product Manager at Knauf Insulation. “Having a standalone Agrément certificate from the BBA for our Rocksilk® EWI Slabs means that system designers and installers can work with a product that is already approved, saving them valuable time and reducing their workload. It’s a win for everyone involved in the EWI process—us as a manufacturer, system designers, and ultimately the end users.”

EWI System Designers can now take advantage of our BBA-certified insulation, which simplifies their process and reduces overall effort. By incorporating Knauf Insulation’s certified slabs, designers can save both time and money. The BBA also benefits from a streamlined certification process, allowing for quicker updates and more efficient completion of work. This results in a three-way win for system designers, the BBA, and Knauf Insulation.

Our Rocksilk® EWI Slabs are specifically designed for use in External Wall Insulation systems. They are versatile, allowing for both either adhered and mechanically-fixed applications or solely mechanically-fixed to the substrate. The product’s superior reaction to fire performance eliminates the need for fire barriers, providing a simple, quick, and economical solution.
