Fire Safety

Non-combustible core structure maintains stability under extreme heat conditions, achieving 120+ minute fire ratings in wall assemblies with zero flame propagation or toxic gas emission during fire exposure.

Moisture & Weather Resistance

Sealed metal facing combined with integrated edge systems provides protection against water infiltration. Panel performance remains stable across temperature ranges from -30°C to +60°C and humidity levels between 30–95% RH

Characteristics

Rockwool insulated wall panels consist of a non-combustible mineral wool core bonded between profiled, pre-coated steel facings. This composite structure provides high structural stability while maintaining consistent insulation performance throughout the building envelope. The panels are resistant to moisture absorption, dimensional movement, and thermal degradation.

The open-fiber composition of mineral wool contributes to effective sound absorption, making these panels suitable for manufacturing plants, logistics facilities, and high-noise operational zones. Controlled factory production ensures uniform density, accurate thickness, and reliable on-site alignment.

Benefits of Mount Rockwool Wall Panels


The Rockwool wall panel fire rating is a critical advantage for facilities with elevated fire risk or strict compliance obligations. Mineral wool insulation is inherently non-combustible, supporting fire compartmentation and limiting flame spread within wall assemblies. Additional benefits include:

Consistent thermal resistance across seasonal and operational extremes

Improved indoor acoustic comfort in industrial environments

Reduced maintenance due to material stability

Long service life supporting asset value preservation

Why Choose Mount Rockwool Wall Panels

  • Fire & Life Safety
    Non-combustible stone wool with A1 fire rating. Does not ignite, spread flame, or emit toxic gases. Maintains structural integrity during fire, supporting safe evacuation and code compliance across all occupancies.
  • Acoustic Performance
    Vertically aligned stone wool fibers absorb airborne and impact noise across 125–4000 Hz. Delivers 25–35 dB noise reduction with high sound absorption (0.85–0.95), ideal for sound-sensitive spaces.
  • Consistent Thermal Insulation
    Stable thermal conductivity of 0.034–0.040 W/m·K. Performance remains unchanged by humidity, temperature, or aging, ensuring reliable insulation for 25+ years.
  • Weather & Moisture Resistance
    Galvanized or coated metal facings resist corrosion. Hydrophobic stone wool core repels over 99% water, preventing mold, sagging, or degradation in humid and wet conditions.
  • Low Maintenance, Long Life
    No settling, compression, or biological growth. Durable facings and inert core result in minimal maintenance and reduced lifetime operating costs.

Mount Advantage

  • Rapid Installation
    Prefabricated panels enable fast, dry wall assembly using mechanical fixing only. Achieves 80–120 m² per crew per day, cutting wall construction time by 50–70% versus conventional methods.
  • All-in-One Performance
    Fire resistance, acoustics, and insulation are integrated into a single panel. Eliminates the need for additional fire boards or sound barriers, simplifying specifications and reducing total installed cost.
  • Factory-Controlled Quality
    Uniform core density, bonding, and facing thickness ensured through controlled manufacturing. Removes on-site variability caused by weather or workmanship.
  • Long Panel Spans
    Panels up to 12 m long reduce joints, limiting thermal bridging and air leakage. Fewer joints mean faster installation and better long-term envelope performance.
  • Lower Lifecycle Costs
    High thermal efficiency reduces HVAC energy consumption by 35–45%. No settling or re-insulation requirements, resulting in lower long-term operating expenses.
  • Simplified Code Approval
    A1 fire-rated, non-combustible panels ease approvals and inspections, avoiding additional fire-barrier requirements and speeding up project timelines.
