rock Wool Acoustic Panels

High-density rock wool acoustic panels for superior sound absorption and thermal insulation in buildings.

Density: 60-150 kg/m³
Thickness: 25-150mm
Asbestos: 100% Non-Asbestos

Overview

✦ Superior sound absorption (high NRC)
✦ Class A non-combustible
✦ Dual thermal and acoustic insulation
✦ Dimensional stability

Specially designed for high-performance sound absorption. Deliver excellent noise reduction coefficients while maintaining outstanding fire resistance and thermal insulation for auditoriums, studios, and industrial noise control.

What Is Rock Wool Acoustic Panels?

Rock wool acoustic panels use the open, porous fibre structure of stone wool to dissipate sound energy, delivering high noise-reduction alongside A1 fire safety for interiors, plant rooms and acoustic enclosures.

Properties & Advantages

High sound absorption across speech and machinery bands
A1 non-combustible — safe behind flammable finishes
Dimensionally stable and sag-resistant
Vapour-open and hydrophobic
Easy to cut, wrap and laminate to facings

Typical Applications

Recording studios, auditoria and theatres
Open-plan office and partition absorption
HVAC plant rooms and machinery enclosures
Acoustic lining of casings and cabinets

Installation & Handling

Fix to a rigid substrate or frame with adhesive, mechanical clips or a fabric-wrap system. Avoid compressing the panel, which reduces both acoustic and thermal performance.

Frequently asked

What temperature can rock wool insulation withstand? +

Rock wool insulation can withstand temperatures up to 650 °C for standard grades. It is classified as a non-combustible material (Euroclass A1, ASTM E84 Class A), making it ideal for structural fire protection, industrial pipe insulation, and building envelope applications.

Does rock wool absorb water? +

No. Our rock wool products feature hydrophobic treatment with water repellency exceeding 98%. Unlike some insulation materials, rock wool maintains its thermal performance even in high-humidity environments. This makes it particularly suitable for outdoor pipework and marine applications.

Is rock wool environmentally friendly? +

Yes. Rock wool is manufactured from volcanic basalt rock — an abundant natural resource. It contains up to 75% recycled content, is fully recyclable at end of life, and contributes to building energy efficiency by reducing heat loss. It is RoHS and REACH compliant.

What density of rock wool insulation should I use? +

The optimal density depends on your application: 60–80 kg/m³ for general thermal insulation of tanks and vessels, 80–120 kg/m³ for pipe insulation and HVAC ductwork, 100–150 kg/m³ for load-bearing or structural applications, and 150+ kg/m³ for high-compression industrial flooring and sandwich panels.
