Products / Sandwich panel, mineral wool core

Sandwich panel, mineral wool core

Steel-faced sandwich panels sourced to your project specification. Core type and thickness affect insulation; exact thermal, structural and fire performance must be confirmed for the selected product.

Thickness: 50 to 200 mm
Core λ: ≈ 0.040 W/m·K
Core density: ≈ 100 kg/m³
Fire performance: Product-specific declaration

EN 14509
EN 14509

More core thickness. Less heat flow through the core.

At an assumed conductivity of 0.040 W/m·K, increasing core thickness by 50% lowers λ/thickness by one third. This comparison illustrates insulation thickness, not a declared panel U-value.

Core thicknesses share a scale; steel facings are exaggerated. Whole-panel U-value, weight, fire rating and span limits require the selected manufacturer’s documents.

Sizes and weights by standard

Weights are theoretical, from nominal dimensions at 7.85 g/cm³: Actual delivered mass and billing basis must be confirmed with the quotation. Verified tables have been checked against the stated standard or catalogue source; Calculated values are nominal estimates, subject to the stated assumptions.

Core-only thermal estimate

Typical values

Illustrative core conductance λ ÷ thickness, using the conductivity assumed below. This is not a declared whole-panel U-value; facings, joints, surface resistances and installation also matter.

Assumed core conductivity for comparison: 0.040 W/m·K. Confirm the product’s declared value with the manufacturer.

Per-product performance

Product-specific

We supply to the specification required for your project. Panel mass, declared U-value, reaction to fire and load/span tables depend on the selected product, facings, joints and installation. Confirm these from the manufacturer’s Declaration of Performance and technical tables when quoting.

We do not publish a figure we have not checked. Need this now? We source it per order: request a quote with the designation from your drawing.

Need a size or standard not listed?

We hold no stock yard, so we are not limited to one. Send the designation from your drawing and we will source the mineral wool sandwich panel to it.
