ISOKING® high-density mineral wool exterior insulation board is premium fireproof mineral wool engineered for external thermal insulation systems (EIFS/ETICS). Featuring Class A1 non-combustibility, low thermal conductivity (≤0.035 W/m·K), high tensile strength, and hydrophobic performance, it provides ultimate fire safety and energy efficiency for building external insulation projects.
ISOKING high-performance mineral wool exterior insulation board is engineered specifically for premium external thermal insulation composite systems (EIFS / ETICS) in commercial, residential, and high-rise construction. Manufactured from natural basalt Mineral melted at extreme temperatures and spun into fine inorganic fibers, our fireproof mineral wool boards provide outstanding thermal conservation, structural integrity, and life-safety protection.
Designed as a heavy-duty thermal insulation board for modern building external insulation projects, this product combines high tensile strength, excellent water repellency, and superior acoustic damping to ensure long-term wall system stability under all weather conditions.
Made from premium fireproof mineral wool with a melting temperature exceeding 1000°C. Prevents flame spread across high-rise facades and releases zero toxic smoke.
Delivers low thermal conductivity (≤ 0.035 W/m·K) to optimize external thermal insulation performance, substantially reducing HVAC power consumption and operating costs.
Engineered mineral wool exterior insulation board structure provides high tensile strength perpendicular to faces, resisting strong wind suction on exterior facades.
Treated with hydrophobic additives achieving ≥98% water repellency, while maintaining high vapor permeability to allow wall moisture evaporation and prevent internal mold growth.
Dense interlocking fiber network absorbs ambient traffic noise while eliminating thermal expansion, warping, or cracking during seasonal temperature shifts.
