Rockwool sandwich panels advantages:
Superior Fire Resistance
rock wool board is non-combustible, not burn,not smoke and can arrived Class A fire rating and it also has heat preservation. Its highest working temperature is 750ºC.
Good Water reprellence
rock wool products greatly reduced by adding special silicone emulsion water repellent agent, thus ensuring the quality requirement for external wall insulation system. Hydrophobic rate is 99%.
Environment Friendly
Free from asbestos, CFCS, HFC, HCFCS and other harmful substances to the environment; our rock wool adopt the resin binder. Do not release any toxic gas at high temperature.
Stable Insulation Performance
rock wool products are free from CFCS or HCFCS that cause the R value to decrease with time, so the thermal resistance value is stable and thermal conductivity does not change with time.it has high tensile strength,it is suitable for exterior building.
Excellent Acoustics
Insulation products absorb airborne sound waves and reduce impact vibration thanks to its density, non-directional fiber orientation and open porous structure.
No Corrosion On Insulation Body
Free from fluorion and chloride, our rock Wool insulation products have no corrosion on the insulation body, even under high temperature environment

Application:
Construction
Rock wool was used for building materials, and steel structure insulation.
soundproof and fireproof used for wall and roof of house.
Heat preservation for steel structure building.
For indoor partition wall, Train compartment.
Industry
Rock wool used for industrial furnace, oven, heat-treating equipment, storage tank, storage groove. power house, flue, petrifaction and oil refining equipment and all kinds of keeping-warm and heat insulation pipelines.
Panel packages and loading reference:
Packing:
Seaworthy packing standards:
PVC on both sides to protect the roof panel surfaces;
Packed with kraft paper to protect the panel ends;
Put EPS foam on the each space to keep the panels from squeezing each other.
If you have special requirement,please feel free to discuss with us.This is to make us improved,and protect your goods well.
Delivery:
Delivery time for regular colors,coating types and thickness: 7-10 days ;
Delivery time for special colors,coating types and thickness: 15-25 days ;
Delivery term: FOB/CIF/CFR/DDP is available;
We can find good forwarder for customer or accept appointed forwarder from customers.
The roof sandwich panels can be sealed by sealing tapes,or if you don't need it,we can cancel,too.And the container loading is by cranes.Then we will also put the thick EPS foam to protect the panels from crashing each other.
