Claim:
1. A method of installing a self-supporting radiant barrier or insulation between longitudinally extending roof joists or wall studs secured to an exterior building surface, comprising in the following order: positioning flexible and resilient strips in a desired longitudinal spacing in an inwardly bowed condition between adjacent roof joists or wall studs to provide air space between the strips and the exterior building surface, the strips being located within interior surfaces of the roof joists or wall studs; thereafter positioning a radiant barrier or insulation that is separate from the bowed strips between the adjacent roof joists or wall studs in a bowed condition in engagement with the bowed strips, the radiant barrier or insulation being located within the interior surfaces of the roof joists or wall studs; and thereafter positioning flexible and resilient rods that are separate from the radiant barrier or insulation in an exposed bowed condition in engagement with the radiant barrier or insulation and over the bowed strips to secure the radiant barrier or insulation in a bowed condition to the underlying bowed strips and the adjacent roof joists or wall studs, the exposed bowed rods being located within the interior surfaces of the roof joists or wall studs; wherein ends of the bowed strips are in engagement with the interior surfaces of the adjacent roof joists or wall studs near the exterior building surface.
