Specification

Rock Wool Sandwich Panel

Rock wool sandwich pamel, also known as stone wool or mineral wool board, is an inorganic fibrous insulation material manufactured by melting natural basalt rock and slag at high temperatures and spinning it into fine fibers. Its key performance characteristics include exceptional fire resistance, superior thermal insulation, and effective acoustic absorption. Additionally, it exhibits high hydrophobicity, chemical stability, and dimensional stability across wide temperature ranges. Primary applications encompass building façade external insulation systems, where it serves as a fire barrier and energy-saving solution. It is also widely used in industrial construction as sandwich panels for warehouses and factories, providing structural integrity and fire compartmentation. In specialized sectors, rock wool boards are essential for shipbuilding, industrial equipment insulation, and cleanrooms due to their non-volatile and moisture-resistant properties.

Sandwich panels are prefabricated composites for steel-framed building envelopes. 

They feature two outer metal skins (typically color steel or aluminum) bonded to a core, forming a lightweight yet structurally robust system. Below is a detailed overview:

1.Outer Skins: Galvanized or painted steel/aluminum sheets (0.3–0.8 mm thick) deliver weather resistance, durability, and aesthetic appeal. Textures include embossed, smooth, or corrugated finishes.

2.Core Materials: rockwool,The density from 80Kg/m3 to 150kg/m3 Light weight, and available fire-retardant options.

3.Outer Skins: Galvanized or painted steel/aluminum sheets (0.3–0.8 mm thick) deliver weather resistance, durability, and aesthetic appeal. Textures include embossed, smooth, or corrugated finishes.

Core Materials: rockwool,The density from 80Kg/m3 to 150kg/m3 Light weight, and available fire-retardant options.
 

Rockwool : Non-combustible, excellent fire resistance (up to 120 minutes), and acoustic insulation.

EPS/Foam: Cost-effective insulation with varying density and fire ratings.

3. Thermal Efficiency: Low U-values reduce heating/cooling costs, meeting strict energy codes.

4. Speed of Installation: Pre-cut panels with interlocking joints enable rapid assembly, minimizing labor and downtime.

5. Structural Performance: High strength-to-weight ratio reduces steel frame loads, optimizing foundation design.

6. Fire & Weather Resistance: rockwool cores offer Class A fire ratings; metal skins withstand corrosion, UV radiation, and extreme temperatures.

7. Design Flexibility:Available in custom lengths, colors, and profiles to suit architectural styles.

8. Applications

Industrial Buildings: Warehouses, factories, cold storage facilities.

Commercial Spaces: Offices, retail outlets, airports.

Residential Construction: Prefab homes, modular buildings.

Cleanrooms & Healthcare: Hygienic, non-porous surfaces resist microbial growth.
