160mm Rockwool NyRock Cavity Slab 032

160mm Rockwool NyRock Cavity Slab 032 is a stone wool insulation slab engineered for complete and partial-fill thermal insulation in masonry cavity walls.

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

Built using cutting-edge patented technology, 160mm NyRock Cavity Slab 032 incorporates an optimised fibre structure that maximises air pocket density throughout each slab. This advanced engineering delivers 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 highest Euroclass A1 non-combustibility classification per EN13501-1.
3. Standard 455mm width aligns with conventional vertical wall tie spacing, delivering flush, gap-free joints between adjacent slabs.

Cavity Walls: This high-performance stone wool insulation delivers exceptional results in masonry cavity wall constructions. The product provides superior thermal insulation, significantly boosting energy efficiency and reducing heat transfer through external walls.

Featuring a Euroclass A1 non-combustible fire rating, this cavity slab substantially enhances building fire safety, making it an excellent choice for residential, commercial, and high-risk environments. Its moisture-resistant and water-repellent characteristics guard against water penetration whilst maintaining cavity breathability.

Lightweight and straightforward to fit, the slabs lock securely between wall ties, creating continuous insulation coverage that elevates building comfort, safety, and thermal performance.

Thermal performance

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

Fire performance

This cavity slab achieves non-combustible status with an A1 reaction to fire classification as defined in EN13501-1. It performs effectively in buildings of all purpose groups, functioning as a reliable cavity barrier when tightly positioned between masonry leaves where insulated walls meet uninsulated cavities.

Acoustic performance

The random fibre orientation and density characteristics of stone wool effectively capture sound waves and dampen vibrations, delivering significant external noise reduction when installed in external walls.

160mm Rockwool insulation maintains its dimensional stability throughout the building's lifespan, ensuring consistent acoustic performance year after year.
