Rock Wool AB Composite Insulation Board
Rock Wool AB Composite Insulation Board is a high-performance insulation solution engineered for modern construction and industrial applications.
Product Description
Rock Wool AB Composite Insulation Board is a high-performance insulation solution engineered for modern construction and industrial applications. This composite board combines high-density rock wool core with advanced insulation facing such as polyurethane (PU) or graphite polystyrene (GPS) to deliver superior thermal insulation, fire resistance (Class A1) and acoustic performance. The Rock Wool AB Composite Insulation Board significantly enhances energy efficiency in buildings and equipment, while meeting stringent fire safety standards required in international markets.
This innovative composite board combines high-density rock wool (A layer) with high-efficiency insulation materials such as polyurethane (PU) or graphite polystyrene (GEPS) (B layer). The AB composite structure provides a perfect balance between fire safety and thermal insulation performance.
Rock wool offers excellent fire resistance and acoustic insulation, while PU or GEPS significantly improves thermal insulation efficiency. This combination makes the board an ideal solution for energy-efficient and fire-safe buildings.

Product Structure
The Rock Wool AB Composite Insulation Board consists of two functional layers:
A Layer – Fire Resistant Rock Wool
The rock wool layer is made from natural basalt fibers and provides:
-
Class A non-combustible fire protection
-
excellent sound absorption
-
high temperature resistance
B Layer – High Efficiency Insulation Material
The second layer uses polyurethane or graphite polystyrene to enhance thermal performance with extremely low thermal conductivity.
This dual-layer structure delivers both high fire resistance and superior insulation efficiency.
