• NyRock Cavity Slab 032 can be used for thermal insulation of external masonry cavity walls, and for the thermal insulation and acoustic protection of masonry party walls between dwellings.
• Certified by the British Board of Agrément (BBA) and granted Certificate 22/6252 as full fill and partial fill thermal insulation in external masonry cavity walls, up to 25 metres in height, in new domestic and non-domestic buildings (additional requirements apply for buildings above 12 metres).
• The NHBC accepts the use of NyRock Cavity Slab 032 in all exposure locations, other than in a full fill application in very severe exposure locations with fair-faced masonry, provided it is installed, used and maintained in accordance with the BBA Certificate, in relation to NHBC Standards, Chapter 6.1, External masonry walls.
• Building standards have also recognized that where party cavity-walls between connected buildings are untreated, considerable heat can escape through them. Using NyRock Cavity Slab 032 to fully fill the party wall will reduce the u-value to 0.00 W/m²K.

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 providing 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.

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.
