Product Description

Product Description

Rock wool composite sandwich panel

The rock wool composite board adds cement mortar plaster on the basis of the rock wool board, strengthens the hardness of the rock wool board, and shortens the construction period of the rock wool board during installation.The rock wool board is made of basalt and other natural ores as the main raw materials. The rock wool board is made into fibers by high-temperature melting, added with an appropriate amount of binder, and solidified. Rock wool board products are suitable for thermal insulation and sound insulation of industrial equipment, construction and ships.

Model type with joint way

Our Rockwool sandwich panels are engineered for superior thermal performance and fire safety. Key models feature the tongue-and-groove joint or the Slim-Lap joint system. These interlocking mechanisms ensure quick, secure installation and create excellent airtight seals. This design is ideal for cold storage, industrial facilities, and any structure requiring robust, energy-efficient cladding with exceptional fire resistance.

Upper and lower surfaces: galvanized color steel, thickness of 0.3-0.7mm. According to the specific requirements of customers, can be colored galvanized steel or galvanized steel. 
Rock wool core material: the density of 120kg / m3; rock wool block staggered laying, the fiber direction perpendicular to the sandwich is still under the surface, and closely Detailed enrich the entire vertical and horizontal surface movement plate. And wool and, through the high intensity blowing agent connections between the lower plate is formed integrally between rock wool blocks. Sophisticated production process to ensure to produce high density rock wool insulation between the body and the metal plate inside the inner wall of strong adhesion, so that the rock wool sandwich panel has good stiffness.

Product advantage

1)Superior Thermal & Fire Insulation
Rockwool sandwich panels provide exceptional thermal insulation and are non-combustible, significantly enhancing building fire safety and energy efficiency.

2)Inherent Fire Retardant Core
The rockwool core is an excellent fire retardant, effectively resisting the spread of flames and contributing to superior fire-rated wall and roof assemblies.

3)Quick and Easy Installation
Their lightweight nature and interlocking joint systems allow for fast, straightforward installation, reducing overall construction time and labor costs.

4)Excellent Cost-Effectiveness
These panels offer an outstanding balance of quality and price, delivering durable, high-performance insulation for a competitive investment.

5)Lightweight Structural Design
The panels are remarkably light, easing handling and logistics while reducing the structural load on the building frame.

6)Airtight and Secure Seals
Advanced joint designs create tight seals between panels, minimizing thermal bridging and ensuring consistent insulation performance.

Product application

These Rockwool sandwich panels are ideal for hotel and prefab house construction. They provide excellent thermal insulation, fire resistance, and acoustic privacy between rooms. Their lightweight yet durable design allows for rapid installation of high-quality walls and roofs, significantly speeding up project timelines.
