120mm Rockwool NyRock Frame Slab 032

120mm Rockwool NyRock Frame Slab 032 is a semi-rigid stone wool insulation slab designed for installation between the studs of external timber or light gauge steel frame walls.

This premium insulation features advanced NyRock technology with a patented high-speed manufacturing process, delivering exceptional thermal conductivity of 0.032 W/mK. It represents the UK's most efficient lambda stone wool insulation solution.

Perfectly sized for standard 600mm stud spacing in both timber and steel frame construction, 120mm NyRock Frame Slab 032 provides rapid, reliable installation. The material's outstanding dimensional stability prevents sagging or slumping, maintaining a continuous protective thermal layer throughout your building's life.

Product specification

• Thickness (mm): 120
• Length (mm): 1200
• Width (mm): 600
• Pieces Per Pack: 2
• m² Per Pack: 1.44
• Reaction to fire (Euroclass): Euroclass A1
• Thermal conductivity: 0.032 W/mK

The innovative NyRock technology creates an optimized fibre structure that maximizes air pocket density within each slab. This advanced engineering delivers superior thermal performance compared to standard stone wool alternatives.

Key features include:

• Exceptionally low thermal conductivity rating of 0.032 W/mK.
• Withstands temperatures above 1,000ºC and achieves the highest Euroclass A1 non-combustibility rating under EN13501-1 standards.
• Proven dimensional stability maintains consistent performance for over 65 years after installation.*
• Resists slumping and sagging thanks to its robust dimensional stability.
• Supplied in 570mm (timber) or 600mm (steel) widths for quick, straightforward frame wall installation.

Applications

120mm NyRock Frame Slab 032 is purpose-engineered for rapid installation within standard 600mm studs of external timber or steel frame walls. Its unique physical structure and strength ensure the stone wool maintains its shape over time, regardless of temperature or humidity changes. The dense fibre composition allows seamless integration into frame walls with minimal cutting, reduced waste, and faster installation. Superior dimensional stability keeps the slabs firmly in place after installation, eliminating sagging or slumping and preventing insulation gaps. This consistency preserves reliable thermal performance across your building's entire lifespan.

Thermal performance

Tested to BS EN 13162:2012 + A1:2015 achieving a thermal conductivity lambda (λ) value of 0.032 W/mK.

Fire performance

NyRock Frame Slab 120mm is non-combustible achieving a reaction to fire classification of A1, as defined in EN13501-1.

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 Insulation.
• When used within an external wall consisting of a rainscreen facade, in combination with NyRock Rainscreen 032, NyRock Frame 032 can deliver result as high as Rw 60dB in a typical wall system, as demonstrated by independent in-situ laboratory testing.
