Note: This professional mineral-wool-insulation Basalt Wool Board supports single-sided or double-sided aluminum foil composite finishing. Custom tongue-and-groove overlapping joint designs are also available, which is ideal for reliable cavity filling behind building curtain walls.
Product Features
Meets Ultra-Low Energy Building Standards: The 100mm thick Basalt Wool Board, as a high-efficiency mineral-wool-insulation material, achieves a heat transfer coefficient K≤0.35 W/(m²·K) in single-layer installation, fully meeting the energy-saving requirements of most hot-summer and cold-winter regions. Double-layer installation can further upgrade the thermal performance to satisfy strict passive house energy efficiency standards.
Vertical Fiber Arrangement, Compression-Resistant and Non-Settling: Adopting a vertical fiber production process with fiber orientation perpendicular to the board surface, this mineral-wool-insulation Basalt Wool Board maintains a thickness retention rate of ≥98% under long-term vertical load from masonry layers and curtain wall joists. It effectively avoids thickness shrinkage, hollowing and top cracking problems, ensuring long-term stable insulation performance.
Product Advantages
Simplified Construction Layers: In exterior wall insulation systems, the integrated 100mm Basalt Wool Board can directly replace traditional composite solutions such as “50mm insulation + 50mm leveling layer” or double-layer 50mm staggered installation. This optimized mineral-wool-insulation application reduces one bonding mortar process and one construction step, cutting overall project costs by approximately 10% while shortening the construction cycle.
Enhanced Fireproof Eaves and Firebreak Performance: With a full 100mm thickness, this mineral-wool-insulation board exceeds the conventional 80mm minimum thickness requirement for standard building firebreaks specified in most regional building codes. When applied to floor slab outer eaves and facade fire separation zones, the Basalt Wool Board forms a reliable vertical fire barrier and effectively restricts upward flame spread along exterior walls, greatly improving building fire safety.
