Help with Heat Conduction Question
My question is:
These days they reinforce concrete walls with steel bars. Would the steel bars enhance or degrade the insulating value of the concrete wall? Explain?
Metal is a good conductor and concrete is a good insulator. My answer so far is that it would degrade the insulating value, because the steel bars inside would conduct the bit of heat that is contained in the concrete, so the concrete will then actually conduct more heat from the outside, thus degrading the insulating value. I'm not sure if this is right...
Is this true or am i missing the point? Please explain, if I'm wrong.
Thanx
