ROCKWOOL has launched NyRock® Cavity Slab 032, a low lambda, non-combustible stone wool slab for full and partial fill masonry cavities that enables a thinner wall construction.
NyRock Cavity Slab 032 has been developed using NyRock technology, a patented production process that creates a more efficient fibre structure than traditional stone wool products. With its 0.032 W/mK thermal conductivity value, users can achieve a U-value of 0.18 W/m²K with a thickness of 150mm, depending on construction type – 25mm thinner than standard stone wool cavity products within the same wall build up.
As with all ROCKWOOL stone wool insulation, NyRock Cavity Slab 032 can withstand temperatures in excess of 1000°C, achieving the highest Euroclass A1 non-combustible reaction to fire classification. It also benefits from a high density semi rigid composition meaning it will not slump in the cavity and retains the same thermal and fire resistance properties more than 55 years after installation.[1] NyRock Cavity Slab 032 also achieves a closely knitted joint with adjacent slabs, without the need for taping of the joints. This helps eliminate gaps allowing for continuity of insulation across the cavity.
Having undergone an extensive testing programme, NyRock Cavity Slab 032 is suitable for new build, renovations and extensions and has British Board of Agrément (BBA) certification for full and partial fill applications.
