Claim 0:
1. An apparatus in an opaque building structure, comprising:
an exterior sheathing having an inner surface; and
a tandem series of highly reflective insulation elements, comprising:
a first highly reflective insulation element comprising:
a first pair of parallel surfaces forming in part a first air space of still air, the first pair of parallel surfaces including the inner surface of the exterior sheathing and a first heat energy highly reflective surface; and
a first material insulation element having a first face supporting the first heat energy highly reflective surface; and

a second highly reflective insulation element comprising:
a second pair of parallel surfaces forming in part a second air space of still air, the second pair of parallel surfaces including a second heat energy highly reflective surface and a third heat energy highly reflective surface; and
a second material insulation element having a first face supporting the third heat energy highly reflective surface; and

wherein the first material insulation element has a second face supporting the second heat energy highly reflective surface.
