NyRock Cavity Slab 032 is a full and partial fill stone wool slab designed for the thermal insulation of masonry cavity walls.
Suitable for use in new builds, renovations or extensions, the lightweight slabs are easy to handle and simple to install proving an accurate fit against the blockwork.
Manufactured using patented technology, NyRock Cavity Slab 032 has a more efficient fibre structure that increases the density of air pockets trapped within each slab. This results in an improved thermal performance when compared to typical stone wool products.
- Low thermal conductivity of 0.032 W/mK.
- NyRock Cavity Slab 032 is able to resist temperatures of over 1,000ºC achieving the highest Euroclass A1 non-combustibility classification as defined in EN13501-1.
- The slabs come in a 455mm width to suit standard vertical wall tie spacings allowing a closely knitted joint with adjacent slabs.
