200mm Rockwool NyRock Cavity Slab 032

200mm Rockwool NyRock Cavity Slab 032 is a stone wool insulation slab engineered for complete-fill and partial-fill thermal insulation applications in masonry cavity walls.

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

Developed using cutting-edge patented technology, 200mm NyRock Cavity Slab 032 incorporates an optimised fibre structure that maximises the concentration of air pockets throughout each slab. This advanced engineering 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, precisely engineered to match conventional vertical wall tie spacing, creating flush, gap-free connections between adjacent slabs.

Cavity Walls: 200mm Rockwool NyRock Cavity Slab 32 delivers premium stone wool insulation specifically engineered for masonry cavity wall systems. It provides exceptional thermal insulation, substantially improving energy efficiency and reducing thermal bridging through exterior walls.

Featuring a Euroclass A1 non-combustible fire classification, 200mm NyRock Cavity Slab 32 significantly enhances building fire safety performance, making it the preferred choice for residential, commercial, and demanding applications. Its moisture-resistant and water-repellent characteristics prevent moisture penetration whilst maintaining cavity breathability.

Lightweight and straightforward to fit, the slabs lock securely between wall ties, delivering continuous insulation coverage that boosts 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 appropriate for use in buildings of all purpose groups, and functions as an effective cavity barrier when securely positioned between masonry leaves where an insulated wall meets an uninsulated cavity section.

Acoustic performance

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

200mm Rockwool insulation maintains its dimensional stability and thickness throughout the building's service life, ensuring consistent acoustic performance year after year.
