The IN`FLECTOR insulating panel is reversible, so the reflective surface can face outward during the seasons when solar gain is a problem, and the carbon PVC surface can face outward during cold seasons to reflect heat back into the building and collect convective sunlight for conversion to radiant heat. The panel is held in place with magnets which form a virtually air tight seal and inhibits infiltration, conduction and convection while providing additional dead air space for insulation.
