Cutting the Windows
- Be careful when you're using sharp tools!!!!
- Mark the lines where you will cut. Check your measurements before you cut.
- Use a metal ruler to guide your cuts.
- Use a SHARP utility kniife or Exacto knife. A sharp knife is safer because you don't have to press so hard to make it cut. That way you have better control.
- Don't try to cut through the cardboard all at once. It works better if you make three or four light cuts instead of pressing hard on the knife.

Putting in the Windows
- Tape one layer of plastic to the inside of the shell or cardboard box
- The second layer of plastic gets taped to the inside of the insulation boards
- You can use any kind of tape that works. Duct tape works well; so does good cellophane tape.

Cutting the Insulation
- Be careful when you're using sharp tools!!!!
- Mark the lines where you will cut. Check your measurements before you cut.
- You can use any kind of insulation that you can cut and fit into the Energy House. One inch is a good thickness. We like using the pink, white or blue styrofoam boards or the kind with foil on both sides.
- If you live near where people are building houses, sometimes they will give you scraps of the insulation board. But please ask them, don't just take it!
- Cut the plastic type of insulation board with a sharp or serrated knife. Serrated knives (the kind with little teeth, sort of like a saw) are used for bread knives or steak knives. Dull knives will crumble the insulation board and get stuck while you're cutting.
