NyRock Cavity Slab

The ROCKWOOL NyRock Cavity Slab 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 a superior 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.

Features and benefits:

Low thermal conductivity of 0.032 W/mK.
NyRock Cavity Slab 032 is able to resist temperatures of over 1,000 ºC achieving the highest Euroclass A1 non-combustibility classification as defined in EN 13501-1.
The slab features an additive to make the product highly water repellent.
The slabs come in a 455 mm width to suit standard vertical wall tie spacings allowing a closely knitted joint with adjacent slabs.
Low lambda non-combustible insulation designed for use in both fully and partially filled masonry cavity walls.
BBA certified for full fill applications (in thicknesses of 100—200 mm), other than in very severe exposure zones with fair-faced masonry.
BBA certified for partial fill applications (in thicknesses of 50—200 mm).
BBA Certificate 22/6252.
