Product Features
Ultra-thin and Flat: This heat-insulation-wool based Basalt Wool Board features precisely controlled 25mm thickness with surface flatness deviation ≤1mm/m². It is perfectly suitable for multi-layer stacking or lamination with gypsum board, calcium silicate board and other decorative boards, providing efficient thermal and acoustic insulation without adding unnecessary structural thickness.
Low Dust, High Flexibility: Adopting professional softening bonding process, the internal fiber structure of the thin Basalt Wool Board is tightly bonded. The finished heat-insulation-wool board has neat cutting edges with a shedding rate of <2% during construction. It also features excellent flexibility and can be slightly bent to fit curved walls and pipeline insulation scenarios, adapting to complex construction surfaces.
Product Advantages
Saves Installation Space: The ultra-thin 25mm design of Basalt Wool Board occupies only half the installation space of conventional 50mm insulation boards. As a compact and efficient heat-insulation-wool material, it is especially ideal for narrow construction areas such as ductwork covering, window frame bottoms, and elevator shaft interiors in renovation projects, effectively saving indoor space and retaining complete indoor headroom without compromising insulation performance.
Improved Construction Efficiency: The lightweight design of this heat-insulation-wool Basalt Wool Board makes a single 25mm×600×1200mm panel weigh only about 2kg. It supports single-person rapid handling, cutting, pasting and nailing operations with simple tools. When applied to equipment casing insulation, it requires no modification to existing support dimensions, greatly simplifying construction procedures and improving overall project efficiency.
