As a manufacturer specializing in high-performance insulation materials, we produce the High Density Rock Wool Slab using dense basalt fiber structures, processed through compression technology. Designed for applications requiring both insulation and structural support, this slab boasts high compressive strength and dimensional stability. The High Density Rock Wool Slab is made from 100% inorganic fibers, ensuring non-combustibility and long-term performance without degradation. The high density enables it to withstand heavy loads, making it suitable for both insulation and load-bearing auxiliary functions in various projects.

Why Choose Us
Our precision compression technology ensures uniform density across the slab, with a density tolerance of ±10%, guaranteeing consistent performance in large projects.
We offer custom density options (200-300 kg/m³) to match specific load-bearing requirements, without increasing lead time.
We provide detailed load-bearing test reports for each batch, supporting structural design calculations for clients.
FAQ
Q: What is the maximum load this High Density Rock Wool Slab can bear?
A: A 100mm thick slab with 250 kg/m³ density can withstand a static load of 50 kN/m² (5 tons per square meter) without permanent deformation, suitable for most non-structural load requirements.
Q: Can it be used in high-temperature industrial floors?
A: Yes. It maintains structural stability at temperatures up to 600℃, making it suitable for industrial floors near furnaces or high-temperature equipment.
Q: How to cut the high-density slab without damaging its structure?
A: We recommend using a diamond saw for clean cuts. Avoid excessive force during cutting, and ensure the cutting tool is sharp to prevent fiber breakage and density loss.
