Medium Density Rock Wool Board 1200x600mm With Temperature Resistance -268℃ ~ 650℃

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. The density of rock wool board is the key indicator determining its performance and application. Products with different densities show significant differences in strength, insulation properties, and cost. Medium-density rock wool boards have a density ranging from 80 to 120 kg/m³. Their thermal conductivity is moderate, approximately 0.042-0.050 W/(m·K), and their insulation effect is slightly lower than that of low-density products but can meet the insulation needs of most buildings. Their compressive strength is about 80-150 kPa, with good flexural resistance, enabling them to bear slight loads.

Good Performance

Some products treated with hydrophobic agents have a hydrophobic rate of ≥98%, allowing them to adapt to slightly humid environments. They are also A1 non-combustible materials, with better structural stability at high temperatures than low-density products, and their fire resistance rating is usually 1-2 hours. Their advantages include balanced overall performance, combining thermal insulation and structural strength, wide application scenarios, and high cost performance. They also have strong adaptability, being usable in dry or slightly humid environments without complex protective treatments. Meanwhile, they have good construction compatibility, capable of being used with rendering mortar, mesh cloth, etc., making them suitable for external wall insulation systems.

Extensive Applications

The main application scenarios of medium-density rock wool boards are extensive. In building external wall insulation, they cover both external and internal wall insulation systems, and are especially suitable for multi-storey buildings, being the most commonly used type of rock wool board in civil buildings. For roof insulation, they are applicable to non-heavy-load areas such as flat roofs, used as insulation layers in conjunction with waterproof layers, which can handle scenarios without large equipment or heavy-duty coverings. Additionally, they are used for ordinary pipe insulation, such as hot water pipes and industrial medium and low-temperature pipes (≤150℃), which can not only achieve insulation effects but also provide a certain degree of structural support.
