Brief: Looking for a straightforward way to solve common insulation challenges in non-load-bearing applications? This video explores lightweight rock wool insulation boards, showcasing their excellent heat preservation and sound absorption properties. You'll see how these boards are ideal for wall interlayers, attics, and duct insulation, and learn about their easy handling and cost-effectiveness.
Related Product Features:
  • Produced from natural basalt rock, melted and spun into fibers for reliable insulation.
  • Features a low density of 40-80 kg/m³, making it lightweight and easy to handle and cut.
  • Offers excellent thermal insulation with low thermal conductivity between 0.038-0.045 W/(m*K).
  • Provides effective sound absorption with a noise reduction coefficient (NRC) of 0.7-0.9.
  • Classified as A1 non-combustible material, ensuring high fire safety standards.
  • Ideal for non-load-bearing applications like wall interlayers, attic insulation, and interior partitions.
  • Suitable for sound-absorbing filling in conference rooms, offices, and machine rooms.
  • Cost-effective solution due to reduced raw material usage and high insulation efficiency.
FAQs:
  • What are the main applications for low-density rock wool insulation boards?
    Low-density rock wool boards are ideal for non-load-bearing and light-load environments requiring thermal insulation or sound absorption. Common applications include filling wall interlayers, insulating interior partitions, attic insulation, ceiling sound-absorbing layers, wall sound-absorbing filling in spaces like conference rooms and offices, and insulation for light pipes such as air conditioning ducts and low-temperature water pipes.
  • How does the thermal performance of low-density rock wool compare to higher density options?
    Low-density rock wool boards offer superior thermal insulation efficiency compared to medium and high-density products at the same thickness. With a thermal conductivity range of 0.038-0.045 W/(m*K), they provide excellent heat preservation, potentially reducing material usage. However, they have lower compressive strength and are not suitable for load-bearing applications where higher density boards would be required.
  • What are the key advantages of using lightweight rock wool insulation boards?
    The key advantages include high insulation efficiency, which can reduce material thickness and usage; low cost due to less raw material consumption; lightweight nature for easy carrying, cutting, and manual installation; and effective sound absorption properties. They are also A1 non-combustible, providing good fire safety, though they may shrink at high temperatures and are not suitable for structural applications.
