Fire protection: As A class A non-combustible material, the rock wool core made of natural rock has a fire resistance limit of more than 4 hours, adding a layer of solid fire protection shield to the building. High density and high strength: Density between 80kg/m³ -150kg /m³, commonly used 120kg/m³, compressive strength ≥150KPa, and two layers of steel closely combined, cope with extreme weather calmly.
Excellent thermal insulation effect: Slender and flexible rock wool fiber, pure rock wool core material thermal conductivity ≤0.043W/ (m · K), high-quality PU edge can be ≤0.025W/ (m · K), keep indoor warm in winter and cool in summer.
Green environmental protection: Inorganic materials are pollution-free, green production process, recyclable
Easy installation: Prefabricated components, an average of 600㎡ -800 ㎡ per day, the construction period is greatly shortened.
