Sandwich panel, PU 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
40 to 200 mm
Core λ

Core density

Standard
EN 14509

More core thickness. Less heat flow through the core.

At an assumed conductivity of 0.022 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: 0.022 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We do not publish a figure we have not checked.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 PU / PIR sandwich panel to it.
