Collapsible radiant barrier void filler

A collapsible radiant barrier void filler, comprising:

• first and second scored sheets having interior and exterior surfaces and fold lines for permitting said first and second sheets to attain collapsed and expanded configurations;
• a cell core structure being collapsible to a closed cell configuration and expandable to an open cell configuration;
• said cell core structure having a first outer strip having an exterior surface directly secured to both a first interior surface of said first scored sheet and a first interior surface of said second scored sheet, and said cell core structure having a second outer strip having an exterior surface directly secured to both a second interior surface of said first scored sheet and a second interior surface of said second scored sheet, and said cell core structure having oppositely disposed cell side portions;
• and
• first and second radiant barrier materials each having a reflective first side and an opposing second side wherein said second side of said first radiant barrier material is secured upon said interior surface of said first scored sheet and said second side of said second radiant barrier material is secured upon said interior surface of said second scored sheet;
• and
• wherein said reflective first sides of said first and second radiant barrier materials face one another in a spaced apart relationship and are respectively juxtaposed adjacent one of said oppositely disposed cell side portions in said expanded open cell configuration so as to maintain an air space adjacent each of said reflective first sides wherein the air space extends into said cell core structure in said open cell configuration.
