Heat conductivity of Compacfoam
| CF100 | λ = 0.0378 W/mK | measurement value |
| CF150 | λ = 0.040 W/mK | average test value |
| CF200 | λ = 0.046 W/mK | average test value |
| CF300 | λ = 0.053 W/mK | average test value |
| CF400 | λ = 0.065 W/mK | average test value |
Due to the small statistical spread, the measurement values scarcely depart from the average test value, and hence they can be applied to the calculation.
Calculation of the total thermal resistance of a component
The total thermal resistance of a 2-D component is determined without consideration of the spatial effects and total heat transmission resistance:
U = λ/d
U: Thermal resistance coefficient in W/(m²K)
λ: specific heat conductivity of this layer in W/(K•m)
d: thickness of the layer in m
e.g.: the U-value of a flat sheet of 50mm Compacfoam CF100 is calculated as follows:
λ(CF100) = 0.0378 W/mK
d = 0.05 m
U = 0.0378/0,05 = 0.756 W/m²K
λ(CF100) = 0,0378 W/mK
d = 0,05 m
U = 0,0378/0,05 = 0,756 W/m²K
