I want to ask about the best material of metal roof insulation and the thickness of the insulation from the interior. Also I want to ask if we can use som materials from nature such as wool,reinforced paper and wood. also I want to know the initial cost of insulating area of 400 m2 and the inlet temperature.

In most residential applications, the insulation is best placed on the attic floor, not on the roof with the roofing system.

I agree, but if youre talking about a commercial building with an exposed metal roofing system, the Spray Polyurethane Foam will provide the highest R value per inch as well as a vapor barrier and wind block. Three inches seems to be the optimal thickness due to the fallacy of the R factor.
