High quality and low cost fire resistant sandwich panels for construction

Our Rook wool Sandwich Wall Panel with sealing side is recombined into a beautiful ,flat,and tough building board by choosing two layers of high-quality color coated steel sheets or other precisely profiled metal sheets as its face plates,rotating the stripped rockwool 90 degrees after roll forming(make the fibers vertical to the upper and lower steel sheets )and strongly binding high-quality rockwool with the metal face plates using high-strength,high adhesion,high-fire-prevention binder. Excellent fire-prevention,thermal insulation,environment protection and other characteristics of the formed boards provide a best choice for industrial building  envelope system.

Advantages of panel:

1. 
   

   Non inflammability and Level A fireproof performance

   
   


2. 
   

   Excellent performance in thermal insulation

   
   


3. 
   

   Biodegradable and environment-friendly

   
   


4. 
   

   Hydrophobic property and high ageing resistance

   
   


5. 
   

   Sound absorption and noise reduction

   
   


6. 
   

   High acidity coefficient can greatly reduce the corrosive action on metals

   
   

 Advantages of core material:

Taking high-quality natural rocks such as basalt,gabbro and others as main materials,the core material is a kind of artificial inorganic fiber after the process of high temperature melting and fiberization with the characteristics of very low slag and dust content and non-absorbent.it is "real rock wool"!
