You have two layer of material to provide insulation. They have heat transfer co-efficient (k1>k2).How will you obtain better insulation?

I dont think you can generalise this problem - at least not for flat plane and cylindrical co-ordinates. It really depends on how much bigger k2 is relative to k1 and how big the pipe thickness is relative to the diameter.

I do have a question here, If the material of lower insulation be bounded to the first system, doesn't that result in heat loss?
