Product Introduction

Rockwool Roof Sandwich Panels are specifically engineered to eliminate the critical risks of fire propagation and thermal bridging in modern steel structures. By utilizing high-density, non-combustible stone wool cores, these panels solve the persistent problem of building code non-compliance and energy loss through the roof. They are widely applied in industrial factories, chemical plants, and commercial warehouses where safety and temperature control are paramount.

Product Specification

Roof Sandwich Panels

Item (mm)	Specifications (mm)
Thickness	50/75/100/150/200
Effective Width	950/980
Length	Length is arbitrary, but due to transportation conditions, it is generally ≤23000

Heat Transfer Coefficient K (Common Specifications)

Items	Specifications
Thickness (mm)	50	75	100	150	200
Heat Transfer Coefficient (W/m²K)	0.749	0.530	0.411	0.268	0.210
Plate Weight (KN/m)	0.644	0.456	0.353	0.230	0.181
Note: The above parameters are calculated based on 0.6mm steel plate, rock wool 130kg/m², and glass wool 70kg/m².

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.
