Rock Wool Insulation (Base) | Residential walls, ceilings, fire barriers | Fire Resistance: Class A1 (EN 13501-1) Thermal Conductivity: 0.044 W/m·K (ISO 8301) Thickness: 50–150mm (ISO 3801) CE Certified | ▲ Excellent fire resistance (non-combustible) ▲ Durable and long-lasting | Higher cost than fiberglass Heavier than foam alternatives |
Rock Wool Insulation (Advanced) | Commercial buildings, high-temperature areas | Fire Resistance: Class A1 Thermal Conductivity: 0.039 W/m·K (▲15% better than Base) Thickness: 50–200mm (▲ extended range) CE & FM Approvals | ▲ Enhanced thermal efficiency (▲) ▲ Customizable thickness up to 200mm | Most expensive option Requires professional installation for thick panels |
Fiberglass Insulation | Residential attics, ductwork | Thermal Conductivity: 0.040 W/m·K (ISO 8301) Fire Resistance: Class A (ASTM E84) Thickness: 25–150mm | Lightweight and easy to install Affordable compared to rock wool | Lower fire resistance (▲ vs rock wool) Potential degradation over time |
Polyurethane Foam Insulation | Commercial roofs, refrigeration units | Thermal Conductivity: 0.020 W/m·K (▲ industry-leading) Fire Resistance: Class B (ASTM E84) Thickness: 20–100mm | ▲ Highest thermal efficiency (▲) Water-resistant and mold-resistant | Flammable (▲ lower fire rating than rock wool) Environmental concerns (CFCs) |
Mineral Wool Insulation | Industrial acoustic barriers | Thermal Conductivity: 0.035 W/m·K Fire Resistance: Class A (ASTM E84) Thickness: 30–200mm | Non-combustible and eco-friendly Excellent acoustic performance | Moderate cost Requires protective gear during installation |
Cellulose Insulation | Retrofitting older homes | Thermal Conductivity: 0.038 W/m·K Fire Resistance: Class A (ASTM E84) Thickness: 10–300mm | Eco-friendly (recycled paper) Affordable and mold-resistant | Moisture-sensitive Lower R-value per inch compared to foam |
