Product Introduction
Wall Rockwool Sandwich Panels are specifically engineered to eliminate the critical risks of fire propagation and thermal bridging in building envelopes. By utilizing high-density, non-combustible stone wool cores sandwiched between durable steel facings, these panels solve the persistent problem of meeting stringent fire safety regulations while reducing energy loss through walls. They are widely applied in industrial plants, commercial complexes, and high-rise buildings where fire protection and insulation are paramount.

Rockwool sandwich panels VS PIR sandwich panels
Here is a detailed comparison table from a buyer's perspective to help you choose between Rockwool and PIR sandwich panels:
|
Comparison Factor |
Rockwool Sandwich Panels |
PIR Sandwich Panels |
|
Core Material |
Dense rock wool fibers made from natural rock |
Rigid polyisocyanurate foam |
|
Fire Performance |
Non-combustible (Class A) . Excellent fire barrier; does not melt or release toxic fumes. |
Combustible (Class B) . Burns and chars but offers better fire resistance than standard PU foam. |
|
Thermal Insulation |
Good sound absorption and stable insulation, but requires greater thickness for extreme temperatures. |
Superior thermal efficiency. Lower thermal conductivity means better energy savings with thinner panels. |
|
Moisture Resistance |
Highly absorbent if damaged or poorly sealed; can lose insulating properties when wet. |
Excellent moisture resistance. High closed-cell rate prevents water absorption. |
|
Weight & Handling |
Heavy and dense. Harder to cut and install; generates dust during cutting. |
Lightweight and rigid. Easy to cut, lift, and install; cleaner job site. |
|
Cost Efficiency |
Generally more expensive due to material weight and complexity. |
More cost-effective. Lower material cost and faster installation reduce total project expenses. |
