Company Info

Basic Info

This high-density rock wool board is developed for building exterior wall external insulation systems, using basalt as the main raw material and made into inorganic fiber board through high-temperature melting. It solves the problem of insufficient fire resistance of traditional insulation materials, and is suitable for exterior wall insulation needs of various residential buildings, commercial buildings. It has multiple functions of insulation, fire protection and sound insulation, complies with domestic and EU building energy conservation standards, can effectively reduce building operating energy consumption, improve indoor living comfort, and meet the high standards of fire acceptance requirements.

Customer reviews

David · Building Energy Efficiency Consultant
Having tested numerous insulation products, I can confidently say this high-density rock wool board delivers outstanding thermal performance. Its λ-value consistently meets specifications, and the hydrophobic treatment effectively prevents moisture absorption - a common issue with lesser products. In our energy audits, buildings using this material show 20-25% better thermal retention compared to standard insulation solutions.
Robert · Civil Engineer
The mechanical properties of these high-density rock wool boards impress me most. With a compressive strength exceeding 60kPa, they withstand heavy exterior finishes without deformation. On our recent hospital project, the material's combination of fire resistance (A1 classification) and thermal efficiency made it the ideal choice. Installation was efficient thanks to the uniform board dimensions and clean cutting edges.

Product Description

Product features:

Adopting the melting blowing process to create a uniform fiber structure, which improves the tensile strength and thermal insulation stability. A waterproof modifier is added to solve the water absorption problem of traditional rock wool. The dry installation can reduce the construction period, and the wet pasting is suitable for complex exterior wall base surfaces. No formaldehyde release meets environmental protection requirements. The fire performance reaches Class A non-combustible, avoiding the risk of fire spread, and can be cut flexibly to meet different thickness requirements.

Product specifications:

The standard board size is 1200mm (length) × 600mm (width), with optional thicknesses of 50mm/75mm/100mm/120mm/150mm. The density is 150kg/m³, and the thermal conductivity is 0.038W/(m·K) under 25℃ conditions. The tensile strength is ≥100kPa, and the compressive strength is ≥40kPa. The water resistance rate is ≥99%, and the combustion performance conforms to the ISO 1182 Class A standard. The environmental indicators meet the E0 class formaldehyde emission limit requirements. The applicable temperature range covers -20℃ to 120℃. The packaging uses moisture-proof plastic film and pallets, with about 200 square meters of boards per pallet.

Product application:

It is suitable for exterior wall insulation systems of residential buildings, commercial office buildings, schools, hospitals and other public buildings. It adapts to various finishing systems such as dry-hanging stone exterior walls and ceramic tile veneer exterior walls. The construction is convenient, and it can be combined with supporting anchors and adhesives to form a complete insulation and fire protection system. It effectively reduces building heat loss and improves indoor constant temperature effect.

Frequently Asked Questions (FAQ)

Q:How does the density of rock wool panels affect insulation performance?
A:Higher density (≥150kg/m³) improves compression strength (≥50kPa) and reduces thermal bridging, enhancing long-term stability. Lower density (80-120kg/m³) suits non-load-bearing applications with cost savings.
Q:What thickness is recommended for high-density rock wool insulation in cold climates?
A:For -20°C regions, 100-120mm thickness with 160kg/m³ density ensures U-value ≤0.30W/m²·K. Thinner panels (80mm) may require additional vapor barriers to prevent condensation.
Q:Can high-density rock wool panels be used for curtain wall insulation?
A:Yes, 160-200kg/m³ density panels with hydrophobic treatment (≥98% water repellency) are certified for curtain walls. They resist wind pressure (≥5kPa) and maintain dimensional stability (±1%).
