Pod filters don't really get "heat soaked" since they are usually made of paper and plastic. The reason for using a box is (as you said later) to pull in air from outside the engine bay.
For that purpose, I would suggest you ditch the insulated aluminum idea (overkill) and just go with a material that is already a decent insulator: plastic. With some quality 1/8" plastic sheet (PE or PP) and epoxy you could make a nice box in any color you want without having to use insulation.
In fact, plastic is such a good idea.... even the OEMs use it.
