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. |
