These methods have a tendency to leave stains, adhesive residues or physical damage on walls surrounding windows, making them undesirable for people who rent their dwellings, or who wish to minimize such damage to their own property. Alternative solutions have used wooden or metal frames to insert into window openings, but these can be costly or time consuming to construct.
In this instructable, a method is described for quickly and non-destructively hanging 1 mil plastic sheeting to the inside of a recessed window opening, creating a good, if imperfect, second pane for winter insulation. It works by holding the plastic in place with spring-tension curtain rods or bamboo rods.
Step 1: Using 6-foot long bamboo
Step 2: Cheap plastic or expensive plastic?
This type is not very transparent, so you won't be seeing much outside. Kind of a shower-door effect.
Step 3: I am glad I don't have to describe this
Bend and place the two bamboo rods inside the window opening.
The bamboo tensions itself against the corners.
