Basalt fiber board can be divided into two categories: solid board and sandwich panel.

Solid panels: These are made of continuous basalt fibers through short cutting, carding, and needling to form a three-dimensional interlaced structure of basalt fiber needle felt, mixed with a small amount of binder under high temperature and pressure.

Sandwich panel: This features a thin solid board for the upper and lower panels, with spliced rock wool strips as the core material, bonded by high temperature and pressure into a durable sandwich structure.

Basalt fiber boards are widely used in modern construction for:

• External insulation of building walls (thin plaster mortar systems and decorative integrated systems).
• Panels for internal wall ceilings.
• Partitions and professional sound-absorbing panels.
