How to Insulate With Bubble Wrap

By Elizabeth Arnold

Using bubble wrap is a fast and effective way to insulate your windows during cold winter months and may result in a lower electric bill. You can easily cut the bubble wrap to fit any window in your home and it's simple to put up and take down. Clear wrap featuring large or medium-sized bubbles is easier to see out of, although wrap with smaller bubbles will still allow light to pass through. As an eco-friendly touch, recycle bubble wrap that was used as packaging rather than buying it new.

Things You'll Need

  • Clear bubble wrap
  • X-acto knife or scissors
  • Water-filled spray bottle
  • Window
  • Pen or marker

Step 1

Determine the width and length of the window using a tape measure.

Step 2

Lay a piece of clear bubble wrap on a flat surface, such as a table. Cut the bubble wrap to fit the window dimensions using an X-acto knife or sharp scissors.

Step 3

Mist the window glass with water using a spray bottle.

Step 4

Press the cut-to-fit piece of bubble wrap onto the wet window. Make sure the wrap's bubble side faces the glass.

Step 5

Grasp a corner of the bubble wrap and pull it off to remove it from the glass. Use a pen or marker to make a small mark on the wrap to help you remember which window it fits. You can reuse the bubble wrap insulation for several years.
