How to Insulate With Paper, Cotton or Aluminum Foil

Wrap pipes or seal cracks that may allow cold air to seep inside the home with several layers of newspaper or cotton fabric to guard against freezing when the mercury drops. Cold, clear nights with temperatures below 20 degrees Fahrenheit pose the greatest risk of frozen pipes -- but freezing is possible any time outside temperatures drop below 32 degrees.

Secure the newspaper or cotton around the pipes with duct tape or twine. For the best insulating effect, the newspaper should hug the pipe -- or fill the crack -- snugly. Check that all areas of the pipe are covered and all cracks are sealed.

Cover pipes wrapped in newspaper or cotton with plastic or aluminum foil and secure the edges with duct tape. Both prevent heat loss and create a protective vapor barrier. Although wrapping with plastic or foil is not required, it may increase the insulating effect of the newspaper.
