a substantially non porous sheet material having dimensions corresponding to a perimeter area of a windowpane of a window;
a spacer and attachment mechanism configured to attach the supplemental window apparatus to the windowpane with the sheet material positioned substantially parallel to the windowpane, wherein the spacer and attachment mechanism determine a distance between the windowpane and the sheet material when the supplemental window apparatus is attached to the windowpane;
a plurality of infiltration blockers attached to the sheet material and configured to substantially enclose a volume of gas between the windowpane and the sheet material when the supplemental window apparatus is installed on the window, the plurality of infiltration blockers each attached to the sheet material along respective edges of the sheet material, wherein infiltration blockers of the plurality of infiltration blockers attached to adjacent edges of the sheet material contact each other at a location proximate to a corner perimeter area of the sheet material, wherein a first infiltration blocker of the plurality of infiltration blockers attached along a first edge of the sheet material overlaps a second infiltration blocker of the plurality of infiltration blockers attached along a second edge of the sheet material, wherein the second edge is adjacent to the first edge.
