Sandwich panel performance data by core and thickness

Compare every Real Panel core across facade, roof and cold room applications. Each table lists the key declared values by panel thickness.

These tables are being finalised — declared values are added from Real Panel’s own test reports and certificates. For figures already available now, use the U-Value Calculator, the product datasheets, or request a value from our technical desk.

How to read these tables

What each column means

Every value in these sandwich panel performance data tables is a declared or tested property of the panel. Lower U-values mean better insulation; reaction-to-fire and acoustic figures come from standardised tests.

λD — thermal conductivity
Declared conductivity of the core (W/m·K). The lower the λ, the better the core insulates for a given thickness.
U-value
Thermal transmittance of the whole panel (W/m²K) at that thickness — lower is better. Calculable from λD and thickness; see the U-Value Calculator.
Weight
Panel self-weight (kg/m²), used for structure, fixings and handling. Varies with core density and facing thickness.
Reaction to fire
Euroclass to EN 13501-1 (e.g. A2-s1,d0 or B-s2,d0). Mineral-wool cores reach the highest, non-combustible classes.
Fire resistance (EI)
Integrity/insulation rating in minutes to EN 13501-2, where the construction has been tested.
Acoustic Rw
Weighted airborne sound reduction (dB) to EN ISO 717-1, where tested.
Reference standards: panels to EN 14509 · U-value method to EN ISO 6946 · reaction to fire to EN 13501-1 · fire resistance to EN 13501-2 · acoustics to EN ISO 717-1.
