- The IN’FLECTOR see thru glowing barrier insulating panel for windows, skylights, and doors is reversible, so the reflective surface can face out during the seasons when solar gain is an issue, and the solar load surface can face out during chilly seasons to reflect heat back into the building and gather convective sun for conversion to glowing heat. The panel is held in place with magnets which form a nearly air tight seal and inhibits convection, conduction and infiltration while supplying added dead air space for insulation.
