Knauf Insulation’s Earthwool® RainScreen Slab has been certified by the British Board of Agrément (BBA) for use in high-rise residential applications and for use behind masonry. BBA certification is recognised globally and gives South African customers reassurance that the products have been rigorously tested for each specified application.

The two BBA certifications cover Earthwool® RainScreen Slab for use on both weathertight ventilated cladding systems and as partial fill insulation on conventional steel-frame walls with a masonry outer leaf. Earthwool® RainScreen Slab is a semi-rigid Rock Mineral Wool insulation slab suitable for use on both domestic and non-domestic buildings. It is non-combustible, achieving the best possible A1 Euroclass Reaction to Fire Classification.

“Non-combustible insulation is the right choice for architects, specifiers, contractors and homeowners as it will not contribute to the development or spread of fire,” said Suria Ramnarain, Sales Development Manager at Knauf Insulation. “BBA certification ensures customers specifying or installing Earthwool® RainScreen Slab can have absolute confidence in its quality and performance for buildings of any height or for any rainscreen application.”

Earthwool® RainScreen Slab has a thermal conductivity of 0.034W/mK. It offers superior robustness and durability, with a water repellent additive to preserve its integrity while exposed during construction. It has been wind load tested by the Building Research Establishment to a maximum design pressure of 3,600Pa or 76m/s – the equivalent of a category 5 hurricane.

Earthwool® RainScreen Slab is optimised for ease of installation. The improved robustness of the product makes it easy to manoeuvre in place, and it is designed to adapt to minor imperfections in the substrate.

“Earthwool RainScreen Slab is a highly versatile insulation solution that offers superior thermal performance. This helps property owners to save energy by keeping buildings warm when it’s cold and cool when it’s warm,” added Suria.

It is manufactured using ECOSE® Technology, Knauf Insulation’s patented sustainable bio-based binder that contains no added phenol or formaldehyde. As a result, products made using ECOSE® Technology are less energy-intensive than mineral wool products made using traditional chemical-based binders, further reducing their ecological footprint. They are also odourless, softer to touch and have the best possible Eurofins Gold Certificate for Indoor Air Comfort, contributing to a high level of indoor air quality.

Thanks to compression packaging, there is more product per pack, and therefore per pallet, and less packaging is used. As a result, Knauf Insulation products require less handling and storage space, helping to improve logistics and efficiencies on site.
