150mm Rockwool NyRock Cavity Slab 032

150mm Rockwool NyRock Cavity Slab 032 is a stone wool insulation slab engineered for full-fill and partial-fill thermal insulation in masonry cavity walls.

Perfect for new builds, refurbishments, and building extensions, these lightweight slabs deliver straightforward installation and guarantee a snug fit against blockwork surfaces.

Built using cutting-edge patented technology, 150mm NyRock Cavity Slab 032 incorporates an optimised fibre structure that maximises air pocket density throughout the slab. This advanced engineering provides outstanding thermal performance that surpasses standard stone wool alternatives.

Key features include

1. Outstanding thermal conductivity of 0.032 W/mK.
2. Withstands temperatures beyond 1,000ºC, attaining the highest Euroclass A1 non-combustibility classification per EN13501-1.
3. Standard 455mm width, perfectly aligned with conventional vertical wall tie spacing, delivering tight, flush joints between adjacent slabs.

Cavity Walls: 150mm Rockwool NyRock Cavity Slab 32 delivers premium stone wool insulation specifically engineered for masonry cavity wall systems. It provides exceptional thermal insulation, boosting energy efficiency and reducing heat transmission through external walls.

Featuring a Euroclass A1 non-combustible fire classification, 150mm NyRock Cavity Slab 32 substantially enhances building fire safety, making it suitable for residential, commercial, and high-risk environments. Its moisture-resistant and water-repellent characteristics block water penetration whilst preserving cavity breathability.

Simple to fit and lightweight, the slabs lock securely between wall ties, delivering continuous insulation coverage that strengthens building comfort, safety, and thermal performance.

Thermal performance

Thermal conductivity value of 0.032 W/mK in accordance with BS EN 13162:2012 +A1:2015.

Fire performance

NyRock Cavity Slab 032 is non-combustible achieving a reaction to fire classification of A1, as defined in EN13501-1. NyRock Cavity Slab 032 is suitable for use in building of every purpose group, also acting as an effective cavity barrier when tightly fitted between masonry leaves where an insulated wall connects with an uninsulated wall cavity.

Acoustic performance

The non-directional fibre orientation and density of stone wool means that sound waves are trapped, and vibrations dampened which can significantly reduce outside sources of noise when used in an external wall.

150mm Rockwool insulation maintains its form and thickness throughout the building's lifespan, ensuring consistent acoustic performance year after year.
