Product Introduction

These rockwool roof sandwich panels are engineered to eliminate the common issues of industrial building inefficiency: high energy costs and fire safety risks. By providing superior thermal insulation and non-combustible core materials, they solve the problem of temperature fluctuation and hazardous fire loads. They are widely used in the construction of steel workshops, warehouses, and logistics centers.

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.
