Budget Fixes for Drafty Windows

Applied to panes with double-sided tape and sealed using the heat from a hair dryer, this inexpensive clear shrink film can allow a room to retain as much as 55 percent of its heat. In a pinch, bubble wrap makes an effective replacement; just push the bubble side of the wrap against the glass and adhere with double-sided tape.
