Ceramic fiber  sandwich panel: 
Ceramic fiber  sandwich panel is shaped by rock wool and steel panel through automatic production line without further jointing at the site, it has good properities of heat preservation and sound insulation, heat insulation, fireproof. 

Usage: Widely used for the roof, exterior walls and internal partitions of industrial and civil buildings which have requirements of fire, sound insulation and thermal insulation, especially for the fire controlling projects. 

Construction: 
1)The upper and lower surfaces: Adopted by galvanized color steel plate, thickness 0.4-0.8mm. According to customer's specific need, it also can be used Galvanized color steel plate or aluminum plate. After rolling by the mould machinery the steel plate is stuck with the rock wool. 
2)Rock wool core material: The density of rock wool block is 120kg/m3, it is staggered and rolled out with its fiber direction perpendicular to the upper and lower surface of the sandwich panel, the rock wool is closely-phase jointed filling the entire vertical and horizontal section of the sandwich panel. The rock wool between the blocks and steel sheet is shaped into one whole block by high-intensity foam, sophisticated process ensures high-density rock wool insulation between the inner body and metal plate can produce a very strong adhesion, which made rock wool sandwich panel has a strong stiffness. 

Product Specifications: 
1) Width <950mm/1150mm, length <120000mm can be fixed according to design requirements and transport conditions 
2) Thickness: 50mm, 75mm, 100mm 
Features: 
1) Good Stiffness: After the polystyrene core material is shaped as a whole, and through heating and pressurizing, it is stuck to the surface of the steel plate. After figuration the sandwich panel has excellent integrity; And there is pressured waves on the upper surface on roof panel, the overall stiffness is better than other similar materials, by connected and fixed with the purlin the stiffness of the wall and roof panel is improved greatly. 
2) Special deduction method: The access of the rock wool roof panel is connected by buckling, protecting the seam from leaking and save the installing parts of panel. 
3) Strong and reasonable fixing method: The roof panel is fixed by the special made tapping M6 and jointed with the purlin thus it can resist typhoon and other the external force, the tapping is in the wave crest of the surface of the roof with special waterproof structure, moreover due to the special structures of the tapping, for example, there is a plastic cap on the screw cap to avoid leakage. 
4) Short installation: No more process on the install site, it can not only keep clean of environment without influencing other production stages but also shorten the time of fixing back plate. 
5) Anti-scratching: There is a pressure-sensitive adhesive film on the surface of the panel to protect the coating surface from scratching damage. 

Advantages: 
1) Good fireproof performance: Using rock wool materials, special process and formula, the sandwich panel has good fire performance. Tests showed that it can stand more than 1000 degree of the fire. 
2)Good thermal insulation: The insulation thermal conductivity of the rock wool sandwich panel is low as λ = 0.043 W/m2 K, 
3) Remarkable sound insulation and absorbtion 
Sound insulation: The Rock wool sandwich panel has a significant reduction of noise transfer, it is particularly applied to place where there are regular flights. In addition, the indoor sound from the impact of the rain, hail, etc also decreased after using rock wool roof panel, but also significantly decreased. 
According to ISO 717/82 and UNI 8270 / 7 criteria, sound insulation effect of rock wool sandwich panel with density of 100kg/m3 rock wool core material can achieve RW = 29 ~ 30 dB.
