Rainscreen Façade Systems are lightweight when compared to brick and masonry solutions and can provide the design freedom to choose from a wide range of aesthetic options.
In addition to thermal performance, ensuring real-world fire performance of insulation is crucial, particularly when designing buildings which are over 11m in height, will have high occupancy levels or will be used by vulnerable occupants.
Our mineral wool insulation solutions provide the required thermal and fire performance and can be installed on buildings of any height.
DID YOU KNOW?
Rocksilk® RainScreen Slab is BBA certified for the broadest range of build-ups and the widest range of thicknesses of any rainscreen solution on the market.
It has a Euroclass A1 reaction to fire classification. It is also manufactured using ECOSE® Technology, our unique bio-based binder which contains no added formaldehyde or phenol. It is soft to touch, easy to handle and generates low levels of dust and VOCs.
GLASS MINERAL WOOL AND ROCK MINERAL WOOL – OFFERING A SUSTAINABLE SOLUTION IN RAINSCREEN FAÇADE SYSTEMS
By using a combination of Knauf Insulation Rocksilk® RainScreen Slab and OmniFit® Slab 32 or 35, it is possible to achieve lower embodied carbon in your rainscreen façade system than when using a rock mineral wool alternative between the light steel frame studwork.
Choosing OmniFit® Slab 32 or 35 between the studwork is a smart choice when considering sustainability credentials. Not only does glass mineral wool offer lower embodied carbon (including less transport, storage and handling required), but our entire glass mineral wool product range has been awarded the DECLARE 'Red List Free' label. The Declare label is similar to a food nutrition label; it shows clear and transparent details on where a product comes from, what it’s made of, whether it contains or not chemicals featured on the DECLARE ‘Red List’. To achieve the DECLARE label ‘Red List Free’, rigorous testing and disclosure of the entire composition of our glass mineral wool products down to 0.01% has been required.
Other sustainability credentials include:
- Packaging film with 30- 50% recycle plastic content
- Compression packaging (up to 10:1 ratio)
- Lowest embodied carbon of all mainstream insulants
- BS6001 Responsible Sourcing certification
- Third-party verified EPDs available for all our products
- Green Guide A+ rating
- COnstructZero Champion
- Supply Chain Sustainability School - Gold
- Made In Britain
But we don’t stop there…
ECOSE® Technology is our unique bio-based binder which is used in the manufacture of all of our glass mineral wool products, and the majority of our rock mineral wool products, including Rocksilk® RainScreen Slab.
ECOSE® Technology is our unique bio-based binder which is used in the manufacture of all our glass mineral wool products. ECOSE® Technology contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable, and is 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly. Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs, and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.
