Technical data
From the technical data sheet
95–97%Thermal radiation reflectivityReflectivity: the proportion of the radiant heat reaching the foil that is sent back. What it means →
0.05EmissivityprEN 15976Emissivity: an emissivity of 0.05 means that the aluminium face radiates only 5% of the heat that an ordinary surface would radiate, and therefore does not give off heat by radiation. The lower the value, the better. What it means →
190 mWater vapour diffusion resistance, SdEN 13859-1Sd (m): the degree to which the membrane resists the passage of water vapour, expressed as an equivalent air-layer thickness; high Sd = vapour barrier, low Sd = diffusion membrane, which allows vapour to escape. What it means →
