Dimensionally stable stonewool boards maintain constant insulation values (0.037-0.038 W/mK) under all climatic conditions.
Open fiber structure provides excellent sound absorption and impact noise reduction for flat roof constructions.
- Non-combustible A1 classification (EN 13501-1)
- Melting point exceeds 1000°C
- No smoke or burning droplets in fire conditions
- No release of aggressive or environmentally unfriendly substances
Excellent compressive strength (≥40 kPa) and point load resistance supports foot traffic during installation and maintenance.
Water absorption <0.5 kg/m² (EN 1609 compliant) with moisture resistance meeting ASTM C1104/1104M requirements.
Virtually zero thermal expansion coefficient eliminates need for additional mechanical fasteners and prevents stress on waterproofing membranes.
Chemically neutral composition contains no solvents, oils, softening agents, or corrosive components.
Ideal for workshops, airports, shopping malls, sports venues, storage facilities, and other steel-structure metal roofing systems or concrete flat roofing requiring high compressive strength and point load capacity.
- High compressive strength (≥40 kPa)
- Rigid structural integrity
- Superior fire resistance (A1 classification)
- Excellent thermal and acoustic insulation
- Proven dimensional stability
- Comprehensive moisture and water protection
