Reaction to fire: A2-s1,d0
Non-combustible; does not produce smoke or flaming droplets/particles during combustion.
Density: 100 kg/m³ and 120 kg/m³
Its mechanical strength makes it suitable for structural applications, as it can withstand external pressures and building loads.
Thermal conductivity (λ): 0.033 W/mK
Its low thermal conductivity provides excellent insulation, reducing heat losses and supporting the building’s energy performance.
Water/vapour permeability: μ = 1
The low water vapour resistance supports low moisture absorption and increased resistance to corrosion and wear, making it suitable for humid environments and harsh weather conditions.
Sound insulation: Thanks to its density, it delivers excellent acoustic performance.
Durability: Retains its properties without deterioration or breakdown over time.
Environmental performance: Biosoluble
Free from substances hazardous to health, recyclable, and manufactured in line with environmental standards.
