Insulation Against Metal Siding

I have been thinking about 1 5 rigid foam insulation that has foil on one side for a radiant barrier and installing this directly against the steel frame on the inside the foil side facing out.

Insulation against metal siding.

That would leave a 1 5 air space between the foil side and the metal siding. If you do decide to insulate the metal siding styrofoam insulation would be a valid type of insulation to consider.

By installing the radiant barrier insulation between the frame and the panels you are redirecting that heat transfer away from the frame system of the building essentially blocking it from entering your. Metal roofs are durable and last much longer than conventional roof deck and shingle constructions but they come with a drawback. Installing this insulation type may seem unorthodox to some people for metal structures and that is accurate.
