becomes double
Explanation:
Thermal conductivity of the material is given by
k = Q/t * L/A(T1-T2)
where
t - time
Q - Thermal energy
L - Length (Thickness)
A - Area
(T1-T2) - Temperature difference
From this formula, we can infer that thermal conductivity is directly proportional to the thickness of the material. Therefore, when the thickness doubles, the thermal conductivity becomes double.

thermal conductivity is the property of a material of how well it can conduct thermal energy
therefore increasing the thickness won't affect the conductivity but it might affect the amount of heat energy conducted due increase in dissipation and other such factors.
