This clear heat shrink film can allow a room to retain as much as 55 percent of its heat! Apply to panes with double-sided tape and seal using heat from a hair dryer. If need be, bubble wrap makes a suitable alternative; simply push the bubble side of the wrap against the glass and adhere with double-sided tape.

Eliminate frigid air from slipping through windowsills with a snake. You can purchase these online, or make one yourself by filling a tube of fabric, like an old knee sock, with dry rice.

Though it calls for a greater investment of your time, you can rest easy knowing your leaks are permanently sealed.
