Medium Density Rock Wool Board

Product Description

Cost-effective Medium-density Rock Wool Boards With Overall Excellent Performance

Rock wool boards are produced using natural minerals like basalt as raw materials. The rocks are melted at high temperatures, then spun into fibers via centrifugal force.

Product Characteristics

The density of rock wool board is the key indicator determining its performance and application. Medium-density rock wool boards have a density ranging from 80 to 120 kg/m³ with these properties:

Thermal conductivity: 0.042-0.050 W/(m*K)
Compressive strength: 80-150 kPa with good flexural resistance
Hydrophobic rate ≥98% (when treated with hydrophobic agents)
A1 non-combustible materials with 1-2 hours fire resistance rating
Better structural stability at high temperatures than low-density products

Key Advantages

Balanced combination of thermal insulation and structural strength
Wide application scenarios with high cost performance
Strong adaptability to dry or slightly humid environments
Excellent construction compatibility with rendering mortar and mesh cloth

Primary Applications

External and internal wall insulation systems in multi-storey buildings
Non-heavy-load roof insulation (flat roofs with waterproof layers)
Hot water pipes and industrial medium/low-temperature pipes (≤150℃)

Comparison of Rock Wool Boards by Density

Category	Parameters	Performance	Advantages	Main Applications
Low-Density	40-80 kg/m³; 0.038-0.045 W/(m*K); 30-80 kPa	Excellent insulation, low strength, Class A1 non-combustible	High insulation efficiency, low cost, lightweight	Non-load-bearing indoor insulation, sound absorption, air duct insulation
Medium-Density	80-120 kg/m³; 0.042-0.050 W/(m*K); 80-150 kPa	Good insulation, moderate strength, 1-2hr fire rating	Balanced performance, wide applications, cost-effective	External wall insulation, roof insulation, pipe insulation
High-Density	120-200 kg/m³; 0.048-0.055 W/(m*K); ≥150 kPa	High strength, 2-4hr fire rating, weather resistant	Structural stability, superior fire safety	Load-bearing parts, fire barriers, industrial kilns
