Emissivity of different surfaces
☞
The values stated in the table are approximate values. Different parameters like surface
geometry or quality can influence the emissivity of an object.
Surface Emissivity Surface Emissivity
asphalt 0,90 – 0,98 paints (matt) 0,97
concrete 0,94 human skin 0,98
ice 0,96 – 0.98 mortar 0,89 – 0,91
iron oxide 0,78 – 0,82 paper 0,70 – 0,94
soil, humus 0.92 – 0,96 plastic 0,85 – 0,95
gypsum 0,80 – 0,90 sand 0,90
glass/ceramic 0,90 – 0,95 textiles 0,90
rubber (black) 0,94 water 0,92 – 0,96
paints 0,80 – 0,95 bricks 0,93 – 0,96
