Brief: Join us for a close-up look at this solution and see it in action. In this video, we demonstrate the durable rock wool board's fireproof insulation capabilities, showcasing its stable performance in extreme temperatures and high-humidity environments. You'll learn how its three-dimensional structure ensures long-term resistance to compression and impact, making it ideal for construction projects requiring reliable, long-lasting insulation.
Related Product Features:
  • Class A non-combustible material with inorganic components that ensure fire resistance doesn't weaken over time.
  • Stable thermal insulation performance across a wide temperature range from -268℃ to 700℃ without deformation.
  • Volume water absorption rate below 3% with added water repellents for high-humidity environment suitability.
  • Compressive strength of ≥40kPa (≥80kPa for high-density types) for resistance to long-term loads.
  • Excellent sound insulation performance through fiber structure that blocks air and solid sound transmission.
  • Tensile bond strength ≥0.15MPa when bonded to substrates, reducing cracking and falling risks.
  • Service life exceeding 25 years, matching building design life with proper installation and maintenance.
  • Made from natural rocks, formaldehyde-free, and recyclable for enhanced environmental friendliness.
FAQs:
  • What is the temperature resistance range of this rock wool board?
    The rock wool board maintains stable performance across an extensive temperature range from -268℃ to 700℃, making it suitable for both cold and hot regions without deformation or performance loss.
  • How does this rock wool board perform in high-humidity environments?
    With added water repellents, it has a volume water absorption rate below 3%, preventing reduced insulation performance, weight gain from water absorption, and freeze-thaw damage in humid conditions.
  • What makes this rock wool board suitable for external wall insulation in high-rise buildings?
    Its tensile bond strength of ≥0.15MPa when bonded to substrates resists stress from temperature changes and wind pressure, reducing cracking and falling risks while maintaining stable insulation thickness.
  • How does the fire resistance of rock wool compare to other insulation materials?
    Rock wool boards are Class A non-combustible (highest grade), while polystyrene boards are Class B1-B2 and polyurethane boards are Class B1 with toxic fumes at high temperatures, making rock wool superior for fire safety.
