Frequently asked
What temperature can rock wool insulation withstand? +
Rock wool insulation can withstand temperatures up to 750°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.
