Quick, Easy and Inexpensive
Save money this winter by insulating your windows with bubble-wrap. Bubble-wrap is often used to insulate greenhouse windows in the winter, but it also seems to work fine for windows in the house. You can use it with or without regular or insulating window shades. It also works for windows of irregular shape, which can be difficult to find insulating shades for. It uses the solar power of the plastic and bubbles to create a barrier keeping the heat in. Brilliant!
Just spritz the window with water and lay the wrap on bubble-side against the glass. It will stay on all winter. No glue or tape needed.
