Rockwool has launched NyRock Rainscreen 032 and Frame Slab 032, the first in a series of products that use NyRock technology.
NyRock Rainscreen 032 has been specifically developed for ventilated cladding systems and sealed structures such as curtain walling. It combines a low thermal conductivity of 0.032 W/mK and a non-combustible Euroclass A1 rating along with independently tested acoustic performance and the potential for thinner wall constructions.
Manufactured using patented technology, NyRock Rainscreen 032 has a more
efficient fibre structure than traditional stone wool products, resulting in improved thermal properties. This fibre structure also helps to lessen the transfer of airborne noise, with NyRock Rainscreen 032 achieving a sound reduction index of up to Rw 60 dB when assessed as part of a typical system in independent in-situ laboratory testing.
For optimum thermal performance in framed structures, NyRock Rainscreen Slab 032 should be combined with NyRock Frame Slab 032, a further new addition to the NyRock range, that is purpose designed for fitting between the studwork of external timber or light gauge steel frame walls.
Paul Barrett, Head of Product Management at Rockwool explained: “When working to a U-value of 0.18 W/m2K, specifiers can typically save around 15mm on the wall thickness compared to traditional stone wool products. Applying that saving over a 22m x 22m building of nine storeys, for example, it can yield an extra 99 square feet of usable or profitable floor space.
“The balance between building performance, sustainability and commerciality is a constant challenge for specifiers and building owners. Our NyRock range has been created understanding those pressures, hence deliver lower lambda for thinner walls, while also providing the additional benefits of stone wool including non-combustibility.”
Like its rainscreen counterpart, NyRock Frame Slab 032 can withstand temperatures in excess of 1000°C, achieving the highest Euroclass A1 non-combustible reaction to fire classification.
