100mm Rockwool NyRock Cavity Slab 032

100mm Rockwool NyRock Cavity Slab 032 is a stone wool insulation slab engineered for both complete and partial-fill thermal insulation in masonry cavity walls.

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

Built using cutting-edge patented technology, 100mm NyRock Cavity Slab 032 incorporates an optimised fibre structure that maximises air pocket density throughout the material. This advanced design provides outstanding thermal performance that surpasses standard stone wool alternatives.

Key features include

1. Outstanding thermal conductivity rating of 0.032 W/mK.
2. Withstands temperatures above 1,000ºC, achieving the premium Euroclass A1 non-combustibility classification per EN13501-1.
3. Standard 455mm width, perfectly matched to conventional vertical wall tie spacing, creating tight, consistent joints between adjacent slabs.

Cavity Walls: 100mm Rockwool NyRock Cavity Slab 32 delivers premium stone wool insulation engineered specifically for masonry cavity wall systems. It provides exceptional thermal insulation, boosting energy efficiency and reducing heat transfer through external walls.

Featuring a Euroclass A1 non-combustible fire rating, 100mm NyRock Cavity Slab 32 substantially enhances building fire safety, making it excellent for residential, commercial, and demanding applications. Its moisture-resistant and water-repellent characteristics block water penetration whilst maintaining cavity breathability.

Lightweight and straightforward to fit, the slabs lock securely between wall ties, delivering complete insulation coverage that strengthens building comfort, safety, and thermal efficiency.

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 an A1 reaction to fire classification as defined in EN13501-1. NyRock Cavity Slab 032 is suitable for use in buildings of all purpose groups, and functions as an effective cavity barrier when tightly positioned between masonry leaves where an insulated wall meets an uninsulated wall cavity.

Acoustic performance

The random fibre orientation and density of stone wool work together to capture sound waves and dampen vibrations, which can substantially reduce external noise transmission when installed in an external wall.

100mm Rockwool insulation maintains its form and thickness throughout the building's lifespan, delivering consistent acoustic benefits year after year.
