Product Advantages
1. Superior Fire Resilience
As a Euroclass A1 non-combustible material with a melting point exceeding 1000°C, rock wool boards provide passive fire protection. They do not ignite, propagate flames, or release toxic smoke, maintaining facade integrity during fire exposure and allowing valuable time for evacuation.
2. Exceptional Mechanical Stability
Specifically engineered with high tensile strength perpendicular to the board surface (typically ≥80 kPa), rock wool ensures secure adhesion of the entire ETICS layers (insulation, reinforcing mesh, and render) to the substrate. This resists wind suction loads and minimizes the risk of cracking or delamination in the render system over time.
3. Breathable Building Envelope
Rock wool offers high vapour permeability, unlike closed-cell plastic foams (e.g., EPS or XPS). This allows moisture vapour to diffuse outward, preventing interstitial condensation, mold growth, and structural damage while contributing to healthier indoor air quality.
4. Enhanced Acoustic Comfort
The dense, open-fiber structure of rock wool effectively absorbs sound waves. In external wall applications, it reduces transmission of external noise (e.g., traffic, urban sounds) into the building, providing combined thermal and acoustic insulation benefits for improved occupant comfort.
5. Sustainability and Long-Term Durability
Produced from abundant natural basalt rock, rock wool is an environmentally friendly, recyclable material. It exhibits excellent dimensional stability—with no shrinkage, swelling, or degradation under temperature fluctuations or aging—ensuring consistent thermal performance throughout the building's lifespan.
