An improvement in clear plastic film indoor window insulation kits. The improvement provides a way to open and to close roller window shades or venetian blinds attached to inside window frames after a sheet of clear plastic film has been stretched across the window and secured to the window's casing. The plastic film indoor window insulation kit has reinforced ports which allows roller shade and venetian blind controls to be operated through the reinforced access ports, without removing or damaging the clear plastic film. |
